The Porsche 928, part 4


The 928 S4 variant debuted in the second half of 1986 as a 1987 model, an updated version of the 5.0 L V8 for all markets producing 320 PS (235 kW/316 hp), spotting a new single-disc clutch in manual gearbox cars, larger torquen converter in automatics and fairly significant styling updates which gave the car a cleaner, sleeker look. S4 was much closer in being truly world car than previous models as only major differences between ROW and US models were instrumentation in either kilometers or miles, lighting, front and rear bumper shocks and availability without catalytic converter in many ROW markets. Australian market version was only one with different horsepower rating at 300 PS (221 kW/296 hp) due to preparation for possible low grade fuel. Even this was achieved without engine changes.

A Club Sport variant which was up to 100 Kg lighter became available to continental Europe and USA in 1988. This model was watered down version of 1987 factory prototype which had lightened body and 10.9:1 compression ratio engine. Also in 1987 factory made four white lightened manual gearbox S4 for racecar drivers who were on factory payroll at the time. These were close to same as later actual Club Sport models and can also be considered prototypes for it. An SE (sometimes called the S4 Sport due to model designation on rear bumper), a sort of halfway point between a normally equipped S4 and the more race-oriented Club Sport, became available to the UK. It's generally believed these Porsche Motorsport engined cars have more hp than the S4. They utilize parts which later became known as GT pistons, cams, engine ECU programs and a stronger, short geared manual gearbox. The automatic gearbox was not available.

For 1989 model year visible change inside was digital trip computer in dashboard. At same time Australian model received same 320 PS (235 kW/316 hp) engine management setup as other markets. Porsche debuted the 928 GT in the late winter 1988/89 after dropping the slow selling CS and SE. In terms of equipment, the GT was most like the 928 SE, having more equipment than a Club Sport model but less than a 928 S4 to keep the weight down somewhat. It had the ZF 40% limited-slip differential as standard like the Club Sport and SE before it. Also like the CS and SE, the GT was only available with a manual gearbox. ROW 1989 CS and GT wheels had an RDK tire pressure monitoring system as standard. This was also optional for same year ROW S4. For 1990 model year Porsche made RDK and a 0-100% variable ratio limited-slip called PSD (Porsche SperrDifferential) standard in both GT and S4 models for all markets. This system is much like the one from the 959 and gives the vehicle even more grip. In 1990 the S4 was no longer available with a manual gearbox.

The S4 and GT variants were both cut at end of 1991 model year, making way for the final version of the 928. The 928 GTS came for sale in late 1991 as a 1992 model in Europe and in spring of 1992 as an early 1993 model in North America. Changed bodywork, larger front brakes and a new, more powerful 5.4 L, 350 PS (257 kW/345 hp) engine were the big advertised changes; what Porsche wasn't advertising was the price. Loaded GTS models could eclipse $100,000 USD in 1995, making them among the most expensive cars on the road at the time. This severely hampered sales despite the model's high competancy and long standard equipment list. Porsche discontinued the GTS model that year after shipping only 77 of them to the United States. Total worldwide production for all years was a little over 61,000 cars.

Second-hand models have largely fallen in value, the result of generally high maintenance costs due largely to spare parts that are expensive to manufacture. The earliest versions, however, especially those models with the Bosch K-Jetronic (CIS) injection system, have few electronic components and therefore can be repaired more easily provided spare parts can be found. Various enthusiast supported parts suppliers exist, especially in the United States.

The GTS model has retained a high value however, and as of 2006 the price for all variants is apparently starting to creep upwards (Classic Motorsports, March, 2006 issue, p. 38). A great community dedicated to the 928 exists online even today, and the car has won a huge fan base. The 928 was such a powerful vehicle in its day that even models 25+ years old are able to outperform current sport/grand-touring models of various manufacture.

With the release of the Cayenne sports utility vehicle, Porsche has met with renewed success with a front-engined, V8-powered model. The company's 2005 announcement that a new V8-powered 4-door grand tourer model called Panamera would be launched in 2009 fueled rumours and fan speculation of a reborn 928. Although the Panamera will be a 4-door model, Road and Track magazine published a speculative piece in their April 2006 issue in regards to the possibility of a new, 928-esque coupe that may debut on a shortened version of the Panamera's platform sometime around the 2011 or 2012 model years. Although feasible, this is pure speculation as of 2006. The article seemed to indicate a re-use of the 928 nameplate although Porsche's recent tendency to give non-numerical names to their vehicles and a desire to separate the vehicle from past models may preclude the possibility of calling the vehicle 928.

Also noteworthy is that there are several manufacturers of supercharger and turbo kits specifically for the 928. The stock engine for any year is capable of handling significant power increases without part failure. More owners have opted for supercharging their vehicles as the conversion is reasonably straight forward whereas the fitting of two turbo chargers on each of the exhaust manifolds has caused problems because of the lack of space.

The Porsche 928, part 3


Porsche introduced a refreshed 928 S into the European market in 1980, although it was summer of 1982 and 1983 model year before the model reached North America. Externally, the S wore new front and rear spoilers and sported wider wheels and tires than the older variant, but the main change for the 928 S was under the hood, where a revised 4.7 L engine was used. European versions debuted with 300 PS (221 kW/297 hp), and were upgraded to 310 PS (228 kW/306 hp) for the 1984 model year. From 1984 to 1986 ROW (Rest Of the World) S model was officially called S2 in UK. North American spec 1983 and 1984 S models used, among other differences, milder camshafts and additional emissions regulation equipment, and were limited to 239 hp (174 kW/242 PS) as a result.

As the faster S model was not available in the USA and Canada during the first three years of its existence, a "Competition Group" option was created to allow North American customers to have an S model lookalike with spoilers, 16" flat disc wheels, sport seats, sport springs and Bilstein shocks. Customers could specify paint and interior colors the same way as on a normal 928. The package was available in the 1981 and 1982 model years and was cancelled in 1983 when the S model became available for these markets. Many cars have had S features added by subsequent owners, making original "Competition Group" cars difficult to distinguish without checking option codes.

In 1982, two special models were available for different markets. 205 "Weissach Edition" cars were sold in North America. Unusual features were champagne gold metallic paint, matching brushed gold flat disc wheels, two-tone leather interior, a plaque containing the production number on the dash and the extremely collectible three-piece Porsche luggage set. It's believed these cars were not made with S spoilers even though these were available in USA during this time period as part of the "Competition Group" option. The "Weissach Edition" option was also available for the US market 911 in 1980 and 924 in 1981 model years.

140 special "50th Jubilee" 928 S models were available outside the USA and Canada to celebrate the company's 50 year existence as a car manufacturer. This model is also sometimes referred to as the "Ferry Porsche Edition" because his signature was embroidered into the front seats. It was painted meteor metallic and fitted with flat disc wheels, wine red leather and special striped fabric seat centers. Similar 911 and 924 specials were also made for ROW markets.

Porsche updated the North American 928 S for 1985, replacing the 4.7 L, SOHC engine with a new 5.0 L, DOHC unit sporting four valves per cylinder and producing 288 hp (215 kW/292 PS). Seats were also updated to a new style. These cars are sometimes unofficially called S3 to distinguish them from 16-valve S models. European models kept a 4.7 L engine, which was slightly more powerful, as standard; a little detuned 32-valve engine together with catalytic converters became an option in some European countries and Australia for 1986. That same year, revised suspension settings, larger brakes with 4-piston calipers and modified exhaust was installed on the 928 S, marking the final changes to old body style cars. ROW models received these changes at beginning of model year while North American cars got them only after close to 900 cars were made, starting from VIN 1001. North American version of this late 1986 model is sometimes referred as S3.5 or S3½ because of these changes. The name is little misleading as more than 2/3 of 1986 North American model production had these updates.

The Porsche 928, part 2


The 928 featured a large, front-mounted and water-cooled V8 engine driving the rear wheels. Originally displacing 4.5 L and featuring a single overhead camshaft design, it produced 219 hp (163 kW/222 PS) for the North American market and 240 PS (176 kW/237 hp) in other markets. Porsche upgraded the engine from mechanical to electronic fuel injection in 1980 for US models, although power remained the same. This design marked a major change in direction for Porsche (started with the introduction of the 924 in 1976), whose cars had until then used only rear- or mid-mounted air-cooled flat engines with four or six cylinders.

Porsche utilized a transaxle in the 928 to help achieve 50/50 front/rear weight distribution, aiding the car's balance. Although it weighed more than the difficult to handle 911, its more neutral weight balance and higher power output gave it similar performance on the track. The 928 was regarded as the more relaxing car to drive at the time. It came with either a five-speed dog leg manual transmission, or a Mercedes-Benz-derived automatic transmission, originally with three speeds, with four speed from 1983 in North America and 1984 in other markets. More than half of production had the automatic transmission. Exact percentage of manual gearbox cars for entire production run is not known but its believed to be between 25 and 30%.

The body, styled by Wolfgang Möbius under guidance of Anatole Lapine, was mainly galvanised steel, but the doors, front fenders and hood were aluminium. It had a substantial luggage area accessed via a large hatchback. The new polyurethane elastic bumpers were integrated into the nose and tail and covered in body-coloured plastic; an unusual feature for the time that aided the car visually and reduced its drag. Porsche opted not to offer a convertible variant but some aftermarket modifiers offer convertible conversions.

The 928 qualified as a 2+2, having two small seats in the rear. Both rear seats could be folded down to enlarge the luggage area, and both the front and rear seats had sun visors for occupants. The 928 was also the first vehicle in which the instrument binnacle moved with the adjustable steering wheel, a feature seen more recently on Nissan's 350Z sports car.

The 928 included several other innovations such as the "Weissach Axle", an early all-wheel steering system that provides passive rear-wheel steering in certain off-throttle cornering situations, and an unsleeved, silicon alloy engine block made of aluminium, which reduced weight and provided a highly durable cylinder bore. The concept of all-wheel steering was also adopted later on to several Japanese automobiles, including a Japanese-market version of the Toyota Celica, the Mitsubishi 3000GT VR-4 and the second generation Nissan 300ZX.

Porsche's design and development efforts paid off during the 1978 European Car of the Year competition where the 928 won against the BMW 7-series and the Ford Granada. The 928 is the only sports car so far to have won this competition, where the usual winners are mainstream hatchbacks and sedans/saloons from major European manufacturers. Proof of how advanced the 928 was compared to its contemporaries.

The Porsche 928, part 1


The Porsche 928 is a grand tourer automobile made by Porsche AG of Germany from 1978 model year to 1995 model year, during which time it was one of their most expensive offerings.

Porsche's marketing slogan "It's about as fast as you can go without having to eat airline food" or "It is as fast as you can go without hiring a flight attendant" from the late 1980s where at one point it was the fastest production road-car in the world, having been recorded at 172mph on the salt flats in Utah in 1986 using an early 928 S4. This particular car was originally white but was sprayed bright red for the record attempt to make it stand out more against the salt in marketing material like videos and posters.

By the late 1960s, Porsche had changed significantly as a company, and executives including owner Ferry Porsche were toying with the idea of adding a luxury touring car to the line-up. Managing Director Ernst Fuhrmann was also pressuring Ferdinand to "greenlight" development of the new model in light of concerns that the current flagship at the time, the 911, was quickly reaching its maximum potential where it could soon no longer be improved upon. Slumping sales of the 911 seemed to confirm that the model was approaching the end of its economical life cycle. Fuhrmann envisioned the new range-topping model as being the best possible combination of a sports coupe and a luxury sedan, something well equipped and comfortable enough to be easily driven over long distances that also had the power, poise and handling prowess necessary to be driven like a sports car. This set it apart from the 911, which was a pure sports car.

Ordered by Ferry Porsche to come up with a production-feasible concept for his new model, Fuhrmann initiated a design study in 1971, eventually taking from the process the final specs for the 928. Several drivetrain layouts were considered during early development, including rear and mid-engined designs, but most were dismissed because of technical and/or legislative difficulties. Having the engine, transmission, catalytic converter(s) and exhaust all cramped into a small rear engine bay made emission and noise control more difficult, something Porsche was already facing problems with on the 911 and wanted to avoid. After deciding that the mid-engine layout didn't allow enough room in the passenger compartment, a front engine/rear wheel drive layout was chosen. Porsche also feared at the time that the U.S. government would ban the sale of rear-engined cars in response to the consumer outrage over the Chevrolet Corvair, started by Ralph Nader via his book "Unsafe at Any Speed".

Porsche engineers wanted a large-displacement motor to power the 928, and prototype units were built with a 5.0 L V8 producing close to 300 hp. Very early units used one four-barrel carburetor, which was eventually tossed in favor of Bosch's K-Jetronic fuel injection system. When increasing concern within the company over the pricing and availability of fuel during the oil crisis of the 1970s became an issue of contention, smaller engines were considered in the interest of fuel economy. Some managers began pushing for development of a 3.3 L 180 hp powerplant they had drawn up specs for, but company engineers balked at this suggestion. Both sides finally settled on a 4.5 L, SOHC 16-valve V8 producing 240 PS (219 hp in North America), which they considered to have an acceptable compromise of performance and fuel economy.

The finished car debuted at the 1977 Geneva Motor Show before going on sale later that year as a 1978 model. Although it won early acclaim for its comfort and power, sales were slow. Base prices were much higher than that of the previous range-topping model and its larger size and somewhat odd futuristic styling put off many purists who were more attracted to more compact 911.

Fuhrman's replacement, Peter Schutz, decided that the models should be sold side by side, feeling that the 911 still had potential in the company's line-up. Legislation against rear-engined vehicles also didn't materialize. Although the 928 developed an avid fan following, it never sold in the numbers that Fuhrmann had originally predicted and was discontinued in 1995. The size of the market for expensive and extravagant grand tourers has increased since then, and the company is again looking to capture this market with the Porsche Panamera four-door GT.

The Porsche 924, part 4


In 1986 the 924S was released. Porsche realised with the 944's prices increasing with new standard features and options, they were losing their place as Porsches entry-level model car. While the 924 had always been available in other markets, Porsche decided to re-introduce the 924 to the American market with an initial price under $20,000. The 924S had an old-spec 944 engine producing 150 bhp and drivetrain but with a normal slim 924 body. It also retained the original 924's spartan, VW-like interior. In 1987 the 924S Le Mans (or Special Edition) was made available in limited numbers with a 944 spec 163hp engine, uprated suspension and cosmetically upgraded interior and exterior. This special 924 had manual windows, no sunroof, and no air conditioning to save weight, although you could order one with air conditioning if you so wished.

In 1988, the final year of production for the 924S, the power for all models was brought up to 163 hp (122 kW). This made the 924S faster than the base 944 due to its lighter weight and more aerodynamic body. Due to unfavorable exchange rates in the late 1980s, Porsche decided to focus on upmarket models. They dropped the 924S for the 1989 model year, and stopped producing the base 944 later that same year

The 924 has its own racing series in the form of the 924 Championship in which Jeff May had a pivotal role from the late 1980s until his death on 10th November 2003. Jeff was also one of the founding members of Porsche Club Great Britain. Barry Ashman (the Midlands BRSCC Coordinator) took over the running of the Championship in early 2004. The 924S is also eligible to race in the 944-Spec racing class.

The Porsche 924, part 3


Porsche executives soon recognised the need for a higher-performance version of the 924 that could bridge the gap between the basic 924 and the 911s. Having already found the benefits of turbochargers on several race cars and the 1975 911 Turbo, Porsche chose to use this technology for the 924, eventually introducing the 924 Turbo as a 1978 model.

Porsche started with the same Audi-sourced 2.0 L I4, designed an all new cylinder head (which was hand assembled at Stuttgart), dropped the compression to 7.5:1 and engineered a K-26 turbocharger for it. With 10 psi (70 kPa) boost, output increased to 170 hp (127 kW). The 924 Turbo engine assembly weighed about 65lbs more, so front spring rates and anti-roll bars were revised. Weight distribution was now 49/51 compared to the original 924 figure of 48/52 front to rear.

In order to help make the car more functional, as well as to distinguish it from the naturally-aspirated version, Porsche added a NACA duct in the hood and air intakes in the badge panel in the nose, 15-inch spoke-style alloy wheels, four-wheel disc brakes with 5 stud hubs and a five-speed transmission. Forged 16" flat wheels from the 928 were optional.

Internally, Porsche called it 931 (left hand drive) and 932 (right hand drive), much like the 911 Carrera Turbo, which had been "Type 930". These designations are commonly used by 924 aficionados.

The turbocharged engine allowed the 924's performance to come surprisingly close to that of the 911 SC (180 bhp), thanks in part to a lighter curb weight, but it also brought reliability problems.

Intense heat in the engine bay lead to short turbocharger life and turbo-related seal and seat problems. To fix the problems, Porsche released a revised 924 Turbo series 2 (although badging still read 924 Turbo) in 1981. By using a smaller turbocharger running at increased boost, slightly higher compression of 8:1 and an improved fuel injection system with DITC ignition triggered by the flywheel, reliability improved and power rose to 177 hp (132 kW).

After a successful sales run of both naturally-aspirated and turbo models, in 1981 Porsche decided to surprise everyone and a new 924 variant was unveiled at Le Mans 24 Hours.

By adding an intercooler, increasing compression to 8.5:1 as well as various other little changes, Porsche was able to develop the 924 Turbo into the race car they had wanted, dubbing it the 924 Carrera GT.

Visually it differed to the 931 in that it had polyurethane plastic front and rear flared guards, a polyurethane plastic front spoiler, a top mounted air scoop for the intercooler, a much larger rubber rear spoiler and a flush mounted front windscreen. It lost the 931's NACA duct in the hood but retained the air intakes in the badge panel. This more aggressive styling was later used for as motivation for the 944.

In order to comply with the homologation regulations, the 924 Carrera GT and later 924 Carrera GTS were offered as road cars as well, producing 210 and 245 hp (157 and 183 kW) respectively. Clubsport versions of the GTS were available with a factory included Matter rollcage and race seats. 924 Carrera GT variations were known by model numbers 937 (left hand drive) and 938 (right hand drive).

The ultimate development of the 924 in its race trim was the 924 Carrera GTR race car, which produced 375 hp (280 kW) from a highly modified version of the 2.0 L I4 used in all 924s except for the 944 Carrera GTP which used a highly modified as yet unreleased 944 2.5 litre DOHC 16v Porsche unit. This last model variant came 7th overall at Le Mans 24 Hours and spent the least time out of any other car in the pits.

Production of the 924 Turbo ceased in 1982 except for the Italian market which lasted until 1984. This is due to the restrictions on engines larger than 2 liters, putting the 2.5 liter 944 into a much higher tax category.

The Porsche 924, part 2


The 924 was originally intended to be Volkswagen's flagship coupé sports car. Volkswagen commissioned Porsche to design the car (VW project number 425), who developed a fresh chassis and transmission that would work with an existing Audi I4 engine. They also handled the suspension and the interior and exterior design. Porsche decided on a rear wheel drive layout, and chose a rear transaxle to help provide 48/52 front/rear weight distribution. This slight rear weight bias, despite the front mounted engine, aided both traction and brake balance.

Due to growing concern over the 1973 oil crisis and a change of directors at Volkswagen, they put the 425 project on hold, eventually dumping it entirely after their decision to move forward with the Volkswagen Scirocco model instead. Porsche, who needed a model to replace the 914, made a deal with Volkswagen leadership, agreeing to buy the design for an undisclosed figure—some suggest 100 million DM, others say 160 million—but most agree it was less than the amount Volkswagen paid Porsche to design it.

The deal specified that the car would be built at the ex-NSU factory in Neckarsulm located north of the Porsche headquarters in Stuttgart, the Volkswagen employees would do the actual production line work and that Porsche would own the design. It became one of Porsche's best-selling models to date, and the relative cheapness of building the car made it both profitable and fairly easy for Porsche to finance.

The original design used an Audi-sourced four-speed manual transmission for the 924 mated to VW's EA831 2.0 L I4 engine, previously used in the Audi 100 and Volkswagen LT van and producing 95 hp (71 kW) in North American trim. This was brought up to 110hp (87kw) in mid-1977 with the introduction of a catalytic converter, which reduced the need for power-robbing smog equipment. The four-speed manual was the only transmission available for the initial 1976 model. An Audi three speed automatic was offered starting with the 1977.5 model.

European models, which didn't require any emissions equipment, made 125 hp. They also differed visually from the US spec model by not having the US cars low-speed impact bumpers and the round reflectors on each end of the body.

A 5-speed transmission, available starting in 1979, was a "dogleg" Porsche unit, with first gear below reverse on the left side. This was troublesome and was quickly replaced for 1980 with a normal H-pattern Audi five speed. The brakes were solid discs at the front and drums at the rear. The car was criticised in Car and Driver magazine for this braking arrangement, which was viewed as a step backward from the 914's standard four-wheel disc brakes. However, four wheel disc brakes, five stud hubs and alloys from the 924 Turbo were available on the base 924 as an "S" package starting with the 1980 model year.

The overall styling was penned by Dutchman Harm Lagaay, a member of the Porsche styling team, with the hidden headlights, sloping bonnet line and grille-less nose giving the car its popular wedge shape. The car went on sale in the USA in July 1976 as a 1977 model with a base price of $9,395. Porsche made small improvements to the 924 each model year between 1977 and 1985, but nothing major was changed.

J. Pasha, writing in Excellence magazine, at the time, described the 924 as "the best handling Porsche in stock form".

The Porsche 924


The Porsche 924 was an automobile produced by Porsche AG of Germany from 1976 to 1988. A two-door, 2+2 coupé, the 924 replaced the 914 as the company's entry-level model, and was the model that finally retired the 912. It was the first Porsche model powered by a water-cooled, front-mounted engine to make production, although the similarly-configured 928 was designed before the 924. The front-engine, rear wheel drive arrangement was normal for most other manufacturers, but it was unusual for Porsche, who had previously only used mid or rear-mounted engines of a boxer configuration, all of which had been air-cooled.

The first official appearance of the 924 took place in November 1975 (as a press launch rather than a motorshow appearance) at the harbour at La Grande Motte, Camargue in the south of France. The model was a success and not only helped to take Porsche out of financial ruin, but created the revenue stream needed to continue building and developing the 911. The 924 was replaced by the 944 in 1982 in the US market, but continued to be produced until 1985 in the Rest of World market.

For the 1986 to 1988 model years the car aqquired the powerplant from the 944 model and became the Porsche 924S.

The Porsche 914, part 2


There are different ways to tell which year a particular 914 model was made. The most distinguishable trait are the bumpers. Between 1970 and 1972, both front and rear bumpers were flat across and available in either chrome or painted metal. In 1973, bumper stops were added to the front of the car. And in 1974, bumper stops were added to the front and rear of the car. In 1975 and 1976, the big black bumper years, the bumpers were rubber covered and heavy. Some people like the smooth look of the later bumpers, but most prefer the lighter weight chrome ones. Many people have backdated their bumpers, so this is not always a tell all, but certainly a good starting point for identity.

Another way to distinguish 914's is by the plastic piece that goes around the headlight. White ones are from the first 914s to mid-production of 73. After that, it was a black plastic. Another feature to distinguish the 914 by year is if it has a movable passenger seat, it is 73 and later, while the 72 and earlier had a fixed passenger seat.

Estimates of the number of surviving 914s vary wildly. Because of the cost and availability of repair parts compared to the inexpensive cost of a new chassis, many cars with serious but repairable damage were salvaged over the years. In fact many cars were cut up over the years with the purpose of saving other cars. The increasing scarcity of clean cars is driving up the value of the model.

While the 914 has been out of production for over 30 years, many repair parts are still available. In large part this is due to small companies which specialize in 914 parts, as well as many active car clubs. While a few parts are considered scarce and expensive, (such as US-spec rear turn signal lenses and D-Jetronic Manifold Pressure Sensors), most are available from a variety of mail-order sources while still others are tooled and manufactured. Due to its nimble handling and the low cost of a basic 914, the "poor man's" Porsche of the 1970s has become the poor man's weekend racing car on amateur racing circuits.

Many enthusiasts see the 914 as a blank canvas upon which to create their own automotive dreams. Owners have modified the original four cylinder motors to upwards of 170 horsepower. Many owners instead choose to swap different engines into the 914's sizeable engine bay. These swaps range from Volkswagen turbodiesels, to 911 engines (following in the foosteps of the much sought after 914/6) or Corvair air-cooled sixes, to a small-block Chevy V8. Recently, swaps of Subaru engines have gained popularity among the non-Porsche purists. The 914 is also the base for an electric vehicle conversion kit.

Body modifications are another popular way to personalize a 914. Some of these are simple, such as bolting on fiberglass bumpers that aid the 914 into morphing into a look of the 916 prototype. Some are more extensive, such as installing steel or fiberglass fender flares a la the super-rare 914/6 GT. Some involve completely changing the appearance of the car, often to resemble some other mid-engine car, such as the Porsche 904 or the Ferrari Testarossa. A fiberglass kit was offered in the 1980s dubbed the "9014." The "9014" never found its following, the parts were impossible to find and as a result the car-kit died off, though sometimes an entire car can be spotted on Ebay.

The Porsche 914



The Porsche 914 was a sports car built and sold collaboratively by Volkswagen and Porsche from 1969 through 1976.

By the late 1960s, both Volkswagen and Porsche were in need of new models; Porsche was looking for a replacement for their entry-level 912, and Volkswagen wanted a new range-topping sports coupe to replace the Karmann Ghia. At the time, the vast majority of Volkswagen's developmental work was handled by Porsche, part of a setup that dated back to Porsche's founding; Volkswagen needed to contract out one last project to Porsche to fulfill the contract, and decided to make this that project. Ferdinand Piëch, who was in charge of research and development at Porsche, was put in charge of the 914 project.

Originally intending to sell the vehicle with a flat four-cylinder engine as a Volkswagen and with a flat six-cylinder engine as a Porsche, Porsche decided during development that having Volkswagen and Porsche models sharing the same body would be risky for business in the American market, and convinced Volkswagen to allow them to sell both versions as Porsches in North America.

It appeared to be a perfect win-win situation. On March 1st, 1968 the first 914 prototype was presented. However, development became complicated after the death of Volkswagen's chairman, Heinz Nordhoff, on April 12th, 1968. His successor, Kurt Lotz, was not connected with the Porsche dynasty and the verbal agreement between Volkswagen and Porsche fell apart.

In Lotz's opinion, Volkswagen had all rights to the model, and no incentive to share it with Porsche if they would not share in tooling expenses. With this decision, the price and marketing concept for the 914 had failed before series production had even begun. As a result, the price of the chassis went up considerably, and the 914/6 ended up costing only a bit less than the 911T, Porsche's next lowest price car. This had a serious effect on sales, and the 914/6 sold quite poorly. In contrast, the much less expensive 914-4 became Porsche's top seller during its model run, outselling the 911 by a wide margin, with over 118,000 units sold worldwide.

Volkswagen versions originally came with an 80 hp fuel-injected 1.7 L flat-4 engine based on the Volkswagen air cooled engine. Porsche's 914/6 variant came with a carbureted 110 hp 2.0 L flat-6 engine, taken from the 1969 911T. Karmann manufactured the rolling chassis at their own plant, then either sent them to Porsche for fitment of the Porsche suspension and flat-six engine or kept them in house for Volkswagen hardware. 914/6 models used a similar suspension and brakes to the 911, giving the car handling and braking superiority over the 4-cylinder Volkswagen models in addition to higher power output. A Volkswagen-Porsche joint venture, Volkswagen of America, handled export to the U.S., where both versions were badged and sold as Porsches. In Europe, the four-cylinder cars were sold as Volkswagen-Porsches, at Volkswagen dealerships. This "tainted" the car in the opinion of many automotive critics of that era, and a little of that attitude persists to this day.

Slow sales and rising costs prompted Porsche to discontinue the 914/6 variant in 1972 after producing 3,351 of them; its place in the lineup was filled by a variant powered by a new 95 HP 2.0 L, fuel-injected version of Volkswagen's Type 4 engine in 1973. For 1974, the 1.7 L engine was replaced by a 76HP 1.8 L, and the new Bosch L-Jetronic fuel injection system was added to American units to help with emissions control. 914 production ended in 1976. The 2.0 L flat-4 engine continued to be used in the 912E, which provided an entry-level model until the 924 was introduced.

The 914 was Motor Trend's Import Car of the Year for 1970 and a 914/6 piloted by Frenchmen Claude Ballot-Lena and Guy Chasseuil won the GTS class and finished sixth overall at the 1970 24 Hours of Le Mans.

The Porsche 912


The Porsche 912 was a sports car manufactured by Porsche of Germany between 1965 and 1969 as their entry-level model. The 912 was a nimble-handling compact performance four-seat vehicle also capable of up to 30 mpg fuel economy. This combination was possible based on a combination of high-efficiency petrol engine, low-weight, and low drag. A variant of the Type 911, one of the most famous and successful sports cars of all time, upon initial offering the Type 912 initially outsold the 911, boosting the manufacturer's total production until success of the 911 was assured.

After the discontinuation of the 356 model in 1965, Porsche was left with the pricey new 911 as their only offering. Fearing that its considerable price increase over the 356 would cost the company sales and narrow the appeal of the brand, a decision was made by executives to introduce a new entry-level model. Built on the 911's chassis and sharing its bodyshell, Porsche was able to offer the 912 for much less than a base-model 911 by using the four-cylinder engine from the 356 rather than the 911's "flat" six-cylinder powerplant and by reducing the number of standard features. The proven reliability of the 356's powerplant combined with the 911 bodywork and low price made the 912 a very attractive buy to both new and old customers, and it substantially outsold the 911 during the first few years of production: Porsche produced slightly more than 30,000 units during its five-year production run.

After updating the 911 line-up to include both a more powerful 911S and a less expensive 911T, Porsche executives began to feel that the 912 had become redundant, that the 911 platform was sufficiently diverse and that pricing had largely come into line with market expectations. Owing to this and the desire to introduce a new model, the 912 was discontinued and superseded as Porsche's entry-level model by the 914 in 1970; a vehicle which Porsche had thought would be less expensive for them to manufacture and sell than the 912.

After a six year absence, the model was re-introduced to North America in 1976 as the 912E to occupy the entry-level position left vacant by the discontinuation of the 914, while the new 924 – the 914's official replacement – was being finalized and put into production. The new 912 featured the "G-Series" 911 bodywork and was powered by a 2.0 L version of the Volkswagen air cooled engine, previously used in late-model versions of the 914/4. 2,099 were manufactured in total, and were not officially sold outside the United States.

Sold to the public for street use, the Porsche 912 was also raced, including rally events. Factory Rally Kits were available that included anti-roll bars, racing brake pads, and a dead pedal rest. In 1967 the 912 played a part in Porsche rally history when independent driver Sobieslaw Zasada of Poland drove a 912 to win the European Rally Championship for series touring cars.

The Porsche Type 997


The Porsche Type 997, or simply 997 (nine-nine-seven or nine-ninety-seven) is the project code name for the current version of the sports car Porsche 911, built by the German manufacturer Porsche since 2004. Production began in July 2004 and two variants, the Carrera and Carrera S coupés, were available immediately. The all-wheel drive Carrera 4 and Carrera 4S versions began shipping in November 2005, while the Turbo and GT3 derivatives went on sale in late 2006. The Targa top models are also available.

According to testing carried out by several American automotive publications, the Turbo model can go from 0 to 62mph in about 3.4 seconds. The Carrera S model is capable of going 0 to 60mph in as little as 3.9 seconds, and carries a top speed of 300 km/h (186 mph), while the base Carrera model is slightly slower, able to run 0 to 60mph in 4.4 seconds, with a top speed of 285 km/h (175 mph). Note, however, that these figures contradict the conservative official Porsche figures.

The Carrera 4 and Carrera 4S will use the same engines as the Carrera and Carrera S, respectively. Visually, the rear bodywork is nearly 2 in (50.8 mm) wider over larger tires. The all wheel drive system sends between 5% and 40% of engine torque to the front wheels as needed.

The 997 Turbo debuted in February 2006 at the Geneva Motor Show. It uses a new front bumper with LED parking lights in a horizontal bar through the air intake. The fog lights are moved to the corners of the bumpers. Large air intakes in front of and behind the rear wheels are other obvious visual cues. The retractable rear wing is also one of the highlights, a feature which has been available on the 996 Turbo too.

The engine is reported to be based on the rugged and very reliable 964/GT1 design at 3.6 L with power output at 353 kW (480 PS) and 620 N·m (457 ft·lbf). The turbochargers will include BorgWarner's new Variable Turbine Geometry (VTG), which uses guide vanes located in front of the turbine wheel that modulates inflow angle and speed. While the 911 Turbo is the first non-diesel production car to feature a variable geometry turbine, a similar approach was used by Garrett Systems starting in 1989 with the Shelby CSX, that used variable nozzles instead. The optional Sport Chrono Package includes a temporary 2.9 psi overboost, upping peak torque to 680 N·m (502 ft·lbf) for ten second bursts.

According to official Porsche figures, it produces 480 hp, accelerates 0-100 km/h (62 mph) in 3.7 seconds with the manual transmission, and a has 0-100 km/h (62 mph) time of just 3.4 seconds with the manumatic Tiptronic S transmission, which is more than enough to edge out its current rival from Ferrari, the new F430. It has also recorded a 0-60mph time of 3.2 seconds at the hands of US motoring publication Motor Trend - eclipsing all of its major competitors and even Porsche's own Carrera GT supercar. The 997 Turbo has a top speed of 311 km/h (193 mph).

Possibly one of the most astonishing feats of the Porsche 997 is its 40 - 60 mph time. In second gear, it takes just 1 second.

The Porsche Type 996


The Porsche Type 996 is a sports car, and the version of Porsche's "911" Carrera model sold from 1998 (as a 1999 model) through to 2004. It has since been replaced by the Type 997. At its debut, it featured the most significant changes to the Carrera model since its introduction in 1963. Chief among these is the fully water-cooled engine, replacing the previously air-cooled engines used exclusively by the Carrera models. More stringent noise regulations and higher customer expectations for both refinement and performance made the switch necessary. Other significant changes include a sleeker body with a more steeply raked windshield and a re-designed interior. With these differences in mind, many "purists" consider the 996 to be an altogether different car, at least in spirit, than the Carreras that preceded it, as opposed to being a development of the original.

The first 996s were available as a coupes or cabriolets with either rear wheel or all wheel drive and a 3.4 litre normally aspirated engine producing 300 bhp (224 kW). These cars shared the same front end as the 1996 Porsche Boxster. The design for the "fried egg" headlamp could be traced all the way back to the Porsche Panamericana concept car. In 2000, Porsche debuted the 996 Turbo, equipped with four-wheel-drive and a 3.6 litre, twin turbocharged and intercooled flat six producing 415 bhp (309 kW), making the car capable of 3.9 second 0 to 60 mph times. An "X50" upgrade package was available from the factory in 2002, increasing power to 450 hp (336 kW) through minor revisions to the turbochargers and engine control software. Porsche introduced a Turbo "S" in 2004, featuring the X50 engine upgrades and the formerly optional ceramic brakes as standard equipment. In 2002, the standard models underwent minor re-styling, which included switching to the Turbo-style headlamps and to a new front fascia. These were sometimes known as the Mk.II generation of the 996. In addition, engine capacity was also increased to 3.6 litres across the range, yielding gains of 20 horsepower (15 kW) for the non-Turbo models. 2002 also marked the start of production of the 996 based Targa, featuring a sliding glass "green house" roof system like its Type 993 predeccesor.

Like the 993 before it, the 996 platform was used as the basis for two lightweight GT variants called GT2 and GT3. The GT3 was based on the standard RWD 996 Carrera, but was stripped of a great deal of equipment for weight savings, featured stiffer, adjustable suspension and upgraded brakes, and used the bodyshell of the four-wheel-drive version, which incorporated additional front-end stiffening. It was produced in two versions. The first, commonly referred to as the Mk.I GT3, was released in 1999 in all markets, save North America. It featured a naturally aspirated version 3.6L flat six making 360bhp. This engine was shared with the 996 Turbo and was a derivative of the Le Mans winning engine developed for the 911 GT1. The Mk.II GT3 variant was based on the second generation of the 996, and featured updated aerodynamics, and a more powerful version of the 3.6L engine from the MK.I, now producing 380bhp. The Mk.II was the first GT3 marketed in the North America. In 2004 testing of the Mk.II GT3, the car produced 0-60 times of 4.0 seconds, and produced 1.03 g on the skidpad, the second highest number ever recorded by a street legal automobile. Its counterpart, the GT2, was also RWD only, but received an added group of aerodynamic body parts, ceramic brakes of larger diameter, and a re-tuned version of the 996 Turbo's 3.6 litre, twin turbocharged engine featuring larger turbochargers and intercoolers, revised intake and exhuast systems, and re-programmed engine control software. The result was 477 horsepower (356 kW) and 472 ft·lbf (640 Nm) of torque, enough to launch the car from 0 to 60 in 3.6 seconds and to a top speed of 198 miles per hour (316 km/h). Both cars are available only with six-speed transmissions.

The engines in the 1999 and 2000 version have a large failure rate due to a design error. This problem was fixed in mid 2000. One will notice the resale price difference with these model years.

The 99/00/01 cars are all basically the same. 2002 brought a stiffer body which improved safety and handling. They also added seat belt pretensioners. The Tiptronic in 2000 was modified to allow it to enter manual mode by clicking the steering wheel mounted buttons. The Tiptronic would go back to auto mode after 8 seconds. The 2002 cars received the 996 turbo Tiptronic box which is stronger, shifts faster and had 250 shift modes. 2002 cars also received a 3.6L engine which provided an extra 25bhp. It also had some improved parts helping with some reliability issues on the 3.4L engines. The X74 suspension which lowers and stiffens the car was also available as a 2002+ factory modification. Meanwhile, Variocam Plus is standard for every 996's till production has ended.

The Porsche Type 993, part 4


The GT2 is best described as the race variant of the Turbo. For weight saving reasons the 4WD was deleted. The interior is similar to the Carrera RS. The fenders of the Turbo have been cut and replaced with bolt-on plastic pieces in order to accommodate large racing tires and to ease the repair of damages to the fenders often occurring in racing.

Until 1997, the GT2 had almost the same engine as the Turbo, but delivering 430 hp (DIN). In the last year (model year 1998) output was raised to 450 hp (DIN) and twin ignition was added.

The many racing variants have different engine set-ups depending on the applicable racing series. Power output came as high as 600 bph in a "Evo" version designed for the GT1-series, which was ultimately replaced by the mid-engine 911 GT1.

In Porsche terms, 'Speedster' stands for a Convertible with lowered roof and windshield and a rather spartanic interior.

In contrast to the G-model and the 964, Porsche never officially released a 993 Speedster. However, two were built by the factory: a dark green Speedster equipped with Tiptronic S and 17 inch wheels for Ferdinand Alexander Porsche (his 60th anniversary) in 1995 and another wide-body, silver Speedster with manual transmission and 18 inch wheels for American TV star Jerry Seinfeld in 1998.

After the 3.3 liter G-model Turbo convertible (1987-89), Porsche never officially offered an air-cooled Turbo convertible again. However, in 1995 14 993 Turbo Cabriolets were sold before the introduction of the 993 Turbo coupe. They featured the 360 hp (DIN) single-turbo engine of the 964 Turbo 3.6, a 5-speed manual transmission and the wing of the 964 Turbo 3.6. This required a premium of DM 89,500 (or plus 62%) over the standard 993 Cabriolet's price.

The Porsche Type 993, part 3


The 993 Turbo coupe was released in 1995. It featured a new and widely acclaimed turbocharged engine displacing 3.6 liters. Twin turbochargers and air-to-air intercoolers, electronic engine management, redesigned cylinder heads and other modified engine internals were used. The 993 Turbo was the first Porsche Turbo with all wheel drive. The electronic engine management helped the Turbo to achieve fuel efficiency far superior to any of the previous production Turbos. In connection with two catalytic converters and an on-board-diagnostics-system including four oxygen-sensors, it also made the 993 Turbo the cleanest sports car at its time. The Turbo's bodyshell differs from the Carrera body by widened rear wheel arches (approximately 6 cm), redesigned front and rear bumper moldings, and a fixed rear wing housing the intercoolers. New 18 inch alloy wheels with weight-reducing hollow spokes were standard.

During the second to the last year of production of the 993 (1997), Porsche offered the 993 Turbo S. Ultimately 183 pieces were sold. The Turbo S is a fully loaded Turbo including a power upgrade to 424 hp (SAE) for the American market and to 450 hp (DIN) in other markets. The inclusion of every thinkable amenity including carbon fiber decoration in the interior makes it different to the earlier lightweight, spartanic 964 Turbo S. The 993 Turbo S is easily recognized by yellow brake calipers, a slightly larger wing, a 4-pipe exhaust and air scoops behind the doors. This was the last of the air-cooled turbos; there was no 911 turbo in 1998.

The Carrera 4 S (1996) and later Carrera S (1997) shared the Turbo model's bodyshell, but housed the naturally aspirated Carrera engine in the rear. The 4S came with four wheel drive, and retained the Turbo model's larger brake discs with the characteristic red callipers. It could be described as a "Turbo without the turbochargers and rear wing", whereas the S was in all aspects a standard Carrera underneath (the wider rear fenders were compensated with 31 mm wheel spacers). Both S models had slightly lowered suspension compared to standard Carrera models. The wide body is widely acclaimed for its rear looks, but creates more aerodynamic drag, leading to slightly lower top speeds compared to the narrower siblings (about 5 km/h).

In particular, the Carrera 4S is a popular car. It has much in common with the 30th anniversary-model of the Porsche 964, a naturally aspirated, 4WD Carrera 4 in a Turbo bodyshell. The success of that car caused Porsche to build more than the 911 cars originally planned. After the 993, Porsche continued this model with the 996 Carrera 4 S, again a "Turbo without turbochargers and rear wing".

The Carrera RS is a no-compromise lightweight variant of the Carrera. It features a naturally aspirated 3.8 liter engine with 300 hp (DIN). On the outside, it is easily distinguishable by a special non-retractable rear wing, small front flaps and 3-piece 18 inch aluminum wheels. A closer look would reveal that the headlight washers were deleted for weight saving reasons. Inside the rear seats were deleted, and special racing seats and spartan door cards were installed. Sound proofing was reduced to a minimum.

There exists further RS variants, in particular a track-oriented Carrera RS Clubsport with only limited road usability. The Clubsport has a welded roll cage, and certain comfort features deleted, such as carpets, power windows, a/c and radio. It carries a larger rear wing and deeper chin spoiler.

The Carrera RS was produced in model year 1995 and 1996. It was street legal in European and many other countries, but was not exported to the US. As with the low-quantity RS variants of previous 911 types, owners sometimes attempt to turn their Carreras into RS clones due to the high market value of the RS (in European markets, a well maintained RS could easily achieve a 50 per cent premium over a standard Carrera; list prices showed a 15 per cent premium).

The Porsche Type 993, part 2


The Carrera resembles the "base model" of the 993. It was equipped with the naturally aspirated 3.6 liter M64 engine, further developed from the 964 and combined with a new dual-flow exhaust system featuring now two catalytic converters. In contrast to the 964, Porsche deleted the "2" from the "Carrera" name tag.

The option list of the 993 Carrera (and most other variants) was very long and offered the possibility to configure highly individualized cars: it included up to five different sets of wheels, various suspension set-ups, at least three different seat styles (comfort, sport, racing), uncountable upholstery options including the possibility to have almost any interior element of the car covered with leather, wood or carbon, and various hifi-systems including digital sound processing. Further, Porsche offered to paint the car in any color the customer chose. Even more, the Tequipment- and Exclusive-Programs added further options and built to order almost any specific wishes of customers such as special consoles or even fax-machines or bright yellow interior upholstery.

The Cabriolet, introduced 1995, features a fully electrical softtop reinforced with metal sheets and an automatic windblocker.

Both versions were available with all wheel drive under the tag 'Carrera 4'. From outside the Carrera 4 is distinguishable by clear front turn markers and rear red markers (each instead of orange). The brake calipers are painted silver as is the 'Carrera 4' badge on the hood. The center wheelcaps carry the Carrera 4 logo instead of the Porsche crest.

In contrast to most of the following other variants, production of the Carrera Coupe and Cabriolet ceased in 1997 with the end of model year 1997, except for a very few produced in a shortened 1998 model year.

The Targa version of the 993 was introduced in model year 1996 and saw the debut of a retractable glass roof, a design continued on the 996 and 997 Targa. The glass roof would retract underneath the rear window revealing a large opening. A shade was there to help prevent the greenhouse effect of the closed roof. This system was a complete redesign, as previous Targa models had a removable roof section and a wide B-pillar functioning as a roll bar. The new glass roof design allowed the 993 Targa to retain the same side-on profile as the other 911 Carrera variants and finished with the inconvenience of storing the removed top of the old system. The Targa has the body of the Cabriolet with the Targa glass roof replacing the fabric roof.

The Targa was equipped with distinctive 2-piece 17 inch wheels, which could be ordered as an option on all cars not having standard 18 inch wheels. These distinctive split rim wheels for the 993 Targa where actually much heavier than normal in order to offset the extra weight of the Targa roof, to balance the center of gravity.

A classic limited production vehicle.

The Porsche Type 993, part 1


The Porsche Type 993, or simply 993 (nine-nine-three or nine-ninety-three), was the version of Porsche's 911 model produced from late 1993 through early 1998, replacing the 964. Its discontinuation marked the end of air-cooled Porsches, giving it a special place in the hearts and minds of enthusiasts.

As before, Porsche made several variants of the 911 to satisfy every driver. The Carrera was reliable, safe and fast, and was the sports car you could use every day; the Carrera Cabriolet and Targa were ideal for sporty cruising; the 180mph Turbo and Turbo S were supremely quick; and the uncompromising Carrera RS and GT2 were race-oriented.

One of the most noteworthy changes in the 993 over all preceding 911s is the implementation of an all-alloy multi-arm rear suspension attached to an all-alloy subframe. Its design was derived from the project 989, a four door sedan which never went into production, and was later continued in the 993's successor, type 996. It required the mentioned widening of the rear wheel arches, which itself leant to the 993's new-found stability. This suspension improved the 993s cornering abilities, making it more direct and more stable and helping to reduce the infamous tendency to oversteer if throttle was lifted during hard cornering found in earlier 911s. It even contributed to reduced interior noise.

The 993 was the first generation of 911s to have a standard 6-speed manual transmission — previous cars, except for the exotic Porsche 959, had 4- or 5-speed gearboxes. As the 993 was capable of speeds exceeding 270 km/h, a sixth gear became necessary in order to cover this speed range. In virtually every situation, it was possible to keep the engine in its best torque range above 4500 rpm. The Carrera / Carrera S / Cabriolet and Targa models (2WD) were further available with a "Tiptronic" 4-speed automatic transmission, first introduced in the 964. Beginning with model year 1995, Porsche offered the advanced Tiptronic S with additional steering wheel mounted controls and refined software for smoother, quicker shifts. Since the 993's introduction the tiptronic is capable of recognizing climbs and descents.

Further, the 993s optional all wheel drive system was refined over that of the 964. Porsche departed from the 964's setup consisting of three differentials and revised the system based on the layout from their 959 supercar, replacing the center differential with a viscous coupling unit. In conjunction with the 993s redesigned and recalibrated suspension, this system vastly improved handling characteristics and still retained the stability offered by AWD without having to suffer any compromises in understeer. Its simpler layout even reduced the system's weight. The advantages of this concept were reason enough for Porsche to retain it in all succeeding 911s with AWD.

Other improvements include a new dual-flow exhaust, larger brakes with drilled discs, a revised power steering, etc.

The Porsche 964, part 2


The Speedster, a low-roof convertible version of the 964, returned in October 1992. Based on the Carrera 2, the Speedster was available either in standard or in lightweight, Clubsport trim. Unlike its predecessor, the 911 Speedster, the 964 Speedster was not available with the "Turbo-Look" wider rear arches. As a result, the sales of the 964 edition were disappointing: only 925 units were built in two years, vs 2065 for the previous generation, including 1984 "Turbo-Look". Still, 20 very exclusive "Turbo-Look" units were made as special orders.

Porsche introduced the 964 Turbo model in 1991 as the successor to the 930. Unfortunately, they hadn't had the necessary time to develop a turbocharged version of the 3.6 litre M64 engine, and choose to re-use the 3.3 litre engine from the 930, with several minor revisions that made the engine smoother, less prone to turbo-lag and more powerful, with a total output of 320 bhp (235 kW) @ 5750 rpm. 3,660 964 Turbos were built in total.

Porsche released the 964 Turbo 3.6, also sometimes referred to as the 964 Turbo II three years later in 1994, now featuring a turbocharged version of the 3.6 litre M64 engine and producing 360 bhp (265 kW) @ 5500 rpm, the 3.6 litre powered Turbo was produced only for the 1994 model year, with fewer than 2,000 of them produced in total, making it one of the rarest and most sought after Porsches produced since the 959.

In 1994, the Turbo S was also introduced. With a power of 385 hp, it was one of the fastest cars on the road. The Turbo S was available either with the traditional 964 Turbo 3.6 body, or with the exclusive Flatnose (Flachbau) aka Slantnose option. Option X83 (Japan), X84 (ROW) and X85 (USA), the Turbo S Flatnose, was available in the U.S.A. as a $60,179 USD option on top of the base price $99,000 USD Turbo 3.6. The "Flatnose" option was available when ordering the no charge '36S' option '1994 Turbo "S" Model'. In addition to the Flatnose fenders, it also included the 'X88' option or 'Turbo S' motor, the 'X92' Exclusive front spoiler, 'X93' Exclusive rear spoiler and 'X99' Exclusive rear fender vents. The flatnose option was designed around the model 968 front end for the ROW and USA versions and the 930 style Turbo S front end for Japan (right down to the sill covers on the fenders). 39 Models were made for US markets, 27 for the Rest of the world, and 10 for Japan all in Polar Silver.

The Porsche 964, part 1


The Porsche 964, spoken simply as "nine-six-four" or "nine-sixty-four," is the company's internal name for the version of the Porsche 911 model sold between 1989 and 1993. It featured significant styling revisions over previous versions of the 911, most prominently the more integrated bumpers (fenders), although it was still obviously a 911. It was the first generation of Carrera to be offered with Porsche's Tiptronic automatic transmission (as an option) as well as the first generation to be offered with all wheel drive.

The first 964s available in 1989 were AWD equipped "Carrera 4" models, Porsche added the rear wheel drive Carrera 2 variant to the range in 1990. Both variants were available as a coupe, Targa or Cabriolet. The 964 Carrera was the last generation sold with the traditional "pop top" Targa roof. Later evolutions of the Targa, starting with the 993 generation, replaced that setup with a complex glass-roof "greenhouse" system. A new naturally-aspirated engine called the M64 was used for 964 models, which displaced 3.6 litres and produced 247 bhp (184 kW) @ 6100 rpm.

In 1992, Porsche produced a super-lightweight, rear-wheel-drive only version of the 964 dubbed Carrera RS for the European market. It was based on Porsche's 911 "Carrera Cup" race car and harkened back to the 2.7 and 3.0 RS and RSR models. It featured a revised version of the standard engine, titled M64/03 internally, with an increased power output of 260 bhp (191 kW) and lightweight flywheel coupled to the G50/10 transmission with closer ratios, asymmetrical Limited Slip Differential and steel syncromesh. A track-oriented suspension system with 40 mm lower ride height, stiffer springs, shocks and adjustable stabilizer bars without power steering. A stripped-out interior devoid of power windows or seats, rear seats, air conditioning, cruise control, sound deadening or a stereo system and new racing-bucket front seats were part of the package. The trunk hood was made of aluminum, the chassis was seam welded and sound deadening was deleted. Wheels were made of magnesium and the glass was thinner in the doors and rear window. The Carrera RS is approximately 345 pounds lighter than a USA Carrera 2 model. Also available were a heavier Touring variant (with sound deadening, power seats (if desired), undercarriage protection and power windows) and an N/GT racing variant with a stripped, blank metal interior and a roll cage.

A later ultra-low production version of the RS featuring the Turbo body and a 300 bhp 3.8 litre version of the M64 motor was sold briefly in Europe (Carrera RS 3.8).

The Carrera RS was not sold in the USA because Porsche Cars North America felt the car's aggressive tuning was not suited to the American market. In 1992, 45 USA legal cars that were very similar to the Carrera RS were imported to the USA for a proposed "Porsche Carrera Cup" racing series. This Carrera Cup series was to function as a support race for the USA's CART racing series just as European Carrera Cup supported Formula One racing at the time.

These 45 cars were identical to a Carrera RS other than having airbags (with required electric windows), alarm system, American lighting, American bumpers, aluminum wheels, and standard seats. The cars otherwise had the lightweight seam welded chassis, lightweight interior trim, aluminum hood, lightweight door glass, suspension, brakes, G50/10 transmission and M64/03 engine etc. of the Carrera RS. These cars were approximately 200 pounds lighter than a normal USA Carrera 2 model.

The plan was for Andial, the then equivalent of what is now Porsche Motorsport USA, to convert these cars to full racing specification, however, due to lack of sponsor support for the Carrera Cup series, it was canceled before it began. The 45 cars imported to the USA for this series were then sold, quietly without any advertising so as not to compete with the new RS America, through normal dealer channels. These cars were supplied with a dash plaque which indicated that they were the "Carrera Cup USA Edition".

In order to please devoted American 911 enthusiasts who wanted an RS model, Porsche produced the RS America. The RS America was based on the Carrera 2 and featured the M030 suspension, a partially stripped interior without sound deadening, power steering, power amenities, rear seats or a stereo and had cloth-covered sport seats. The RS America was approx. 160 pounds lighter than a stock Carrera 2 and shipped with the standard 247 hp North American engine.

The Porsche 930


The 930 (usually pronounced nine-thirty) was a sports car built by Porsche, 930 actually being the "type number" for the pre-964 generation 911 Turbo produced between 1975 and 1989. It was Porsche's top-of-the-range model for its entire production duration and at the time of its introduction the fastest production car available in Germany.

Porsche began experimenting with turbocharging technology on their race cars during the late 1960s, and in 1972 began development on a turbocharged version of the 911. Porsche originally needed to produce the car in order to comply with homologation regulations and had intended on marketing it as a street legal race vehicle like the 1973 Carrera 2.7 RS. When the homologation rules changed, Porsche continued to develop the car anyway, deciding to make it a fully-equipped variant of the 911 that would top the model range and give Porsche a more direct competitor to vehicles from Ferrari and Lamborghini, which were more expensive and more exclusive than the standard 911. Although Porsche no longer needed the car to meet homologation requirements, it proved a viable platform for racing vehicles, and became the basis for the 934 and 935 race cars.

Ferdinand "Ferry" Porsche, who was running the company at the time, handed development of the vehicle over to Ernst Fuhrmann, who adapted the turbo-technology originally developed for the 917/30 CAN-AM car to the 3.0 litre flat-six from the Carrera RS 3.0, creating what Porsche internally dubbed as 930. Total output from the engine was 260 hp (DIN), much more than the standard Carrera. In order to ensure that the platform could make the most of the higher power output, a revised suspension, larger brakes and stronger gearbox became part of the package, although some consumers were unhappy with Porsche's use of a 4-speed gearbox whilst a 5-speed was available in the "lesser" Carrera. A "Whale-Tail" rear spoiler was installed to help vent more air to the engine and help create more downforce at the rear of the vehicle, and wider rear wheels with upgraded tires combined with flared wheelarches were added to increase the 911's width and grip, making it more stable.

Porsche badged the vehicle simply as "Turbo" (although early U.S. units were badged as "Turbo Carrera") and debuted it at the Paris auto show in October 1974 before putting it on sale in the spring of 1975; export to the United States began in 1976.

The 930 proved very fast but also very demanding. The 911 was prone to oversteer because of its rear engine layout and short wheelbase; combining those traits with the power of the turbocharged motor, which exhibited significant turbo-lag, made the problem more prevalent. Even though the rear engine layout provided superior traction, sudden bursts of power to the rear wheels in mid-corner could break the tires loose, causing the car to literally spin out of control. This effect was amplified if an unexperienced driver would instinctively lift the throttle in reaction. The vehicle needed to be kept at high revvs during spirited driving to minimise the turbo lag. Skilled drivers quickly learned how to drive the 930 properly, and with that knowledge came the ability to drive the car above and beyond the levels of most other sports cars. Nevertheless, some fatal accidents resulted in product liability law suits brought against Porsche in the U.S.

Porsche made its first and most significant upgrades to the 930 for 1978, enlarging the engine to 3.3 liters and adding an air-to-air intercooler. By cooling the pressurized air charge, the intercooler helped increase power output to 300 hp (DIN); the rear 'whale tail' spoiler was re-profiled and raised slightly to make room for the intercooler.

Changing emissions regulations in Japan and the U.S. forced Porsche to withdraw the 930 from those markets in 1980. Believing the 928 would eventually replace the 911, Fuhrmann cut-back spending on the model, and it was not until Fuhrmann's resignation the company finally committed the financing to re-regulate the car.

The 930 remained available in Europe, and for 1983 a 330 hp (DIN) performance option became available on a build-to-order basis from Porsche. With the add-on came a 4-pipe exhaust system and an additional oil-cooler requiring a remodelled front spoiler and units bearing the add-on often featured additional ventilation holes in the rear fenders and modified rockers.

Porsche offered a "Flachbau" ("slantnose") 930 under the "Sonderwunschprogramm" (special order) program beginning in 1981, an otherwise normal 930 with a 935-style slantnose instead of the normal 911 front end. Each Flachbau unit was handcrafted by remodeling the front fenders. So few were built that the slantnose units often commanded a high premium over sticker, adding to the fact that they required a premium of up to 60 per cent (highly indivdualized cars even more) over the standard price. Several sources claim the factory built 948 units. The Flachbau units delivered in Europe usually featured the 330 hp performance kit.

928 sales had risen slightly by the 1985 model year, but there was still some question as to if it were truly capable of superceeding the 911 as the company's premier model, and for 1986 Porsche re-introduced the 930 to the Japanese and U.S. markets, now featuring an emission-controlled engine producing 282 hp (DIN). At the same time Porsche introduced the Targa and Cabriolet variants, both of which proved popular.

Porsche discontinued the 930 after model year 1989 when its underlying "G-Series" platform was being replaced by the 964. '89 models were the first and only versions of the 930 to feature a 5-speed transmission. A turbo version of the 964 officially succeeded the 930 in 1991 with a modified version of the same 3.3 litre engine and a 5-speed transmission.
