Porsche-924-Turbo
Porsche upgraded the performance of its 924 with the introduction of a turbocharged model in 1979. While the lower end of the engine remained unchanged, many improvements were made to the upper end of the engine as well as the drivetrain. On the outside, the car gained alloy wheels, a distinctive NACA duct in its hood, and a rear spoiler. Horsepower increased from the naturally aspirated 125 bhp to 170 bhp in the turbo.
The 1989/90 change of model year saw the launch of the Porsche 911, 964 series onto the market. This 911 model was initially available as a Coupe, Targa and Convertible. From model year 1991 onwards Porsche also introduced its top-of-the-line model - the Turbo - into this series. In spite of bearing a major similarity in terms of look to the naturally-aspirated model, the extended wings remained. This meant that the new Porsche could retain its turbo look. The 964 Turbo model was the successor to the Porsche 930. The 964 Turbo was the end of an era, the last of the single turbo rear-wheel drive 911 Turbos.
Porsche introduced a new wide-body package option. Known as the M491 option it was commonly known as the "Turbo-Look". It gave the naturally aspirated cars the look and style of the 930 Turbo with wide wheel arches and the distinctive "tea tray" tail. It wasn't just about looks however, because M491 also got you the stiffer suspension shared with the Turbo and the superior Turbo braking system as well as the wider Turbo wheels. It was available on the Coupe, Cab and Targa.
The first road-going 911 Turbo was not the familiar 930 that entered production in February 1975. Nor was it the engine-less prototype that had appeared at the Paris Motor Show in October 1973. Instead, it was a one-off narrow-bodied mule that was subsequently gifted to Ferry Porsche’s sister, Louise, on her 70th birthday in August 1974. Built on chassis 9115600042, this 2.7 Carrera Turbo also pre-dated the prototype 930 that was shown in almost production-ready at Frankfurt show in 1974.
In the 1970s Porsche was serious about turbocharging and this prototype signaled the way for later cars like the 930 and the RSR 3.0. It was also the one of the very first show cars fitted with the wide body, large alloy wheels, whale tail and a turbocharged version of the flat-6. All these details eventually appeared on the 911 RSR 3.0-liter race car of 1974. The show car was built from a standard 911S fixed with a radical body kit.
The 911 SC effectively replaced the 911 S and was one of Porsche's first models that was meant for the international market. It was sold as a cheaper alternative to the 911 Turbo. The SC used an unblown version the 930 Turbo unit that offered 180 to 200 bhp depending on model year. Options included the rear whale tail, front chin spoiler, Bilstein dampers, 16 inch wheels with Pirelli P7 tires and sports seats. Sometimes dealers lumped these options together to create their own sport package. It was available as a Coupe and Targa from 1978 - 1983, while the Cabriolet version was only available in 1983.
For race teams and track day customers Porsche prepared a small number of the 964 Cup cars according to the FIA NG-T regulations. Officially called the Competition model, these custom-ordered cars were an intermediary step between the Carrera Cup option (M001) and the standard tourer (M002). This M0003 option was available directly from Porsche as a road-going model. These cars had almost all the Carrera Cup modifications including the new suspension. This lowered the car by 40mm in the rear and 50mm in the front. It also included fitting of the larger 930 Turbo disc brakes and adjustable anti-roll bars.
porsche 934
Using the 930 Turbo as a basis, Porsche built the 934 for Group 4 GT racing. It replaced the outgoing Carrera RSR while winning GT Championships in Europe and performing very well in America for Trans Am. Porsche built the 934 from a standard 930 bodyshell and production rear spoiler, but almost nothing else was left alone. The suspension was converted to solid mounts and nylon bushings with adjustable anti-roll bars.
The first prototype receiving those modifications was code named “F3”, and was destroyed in the first crash test. A total of 37 prototypes and pre-production cars were used for testing and press activities. Most of these prototypes were dismantled and discarded, but several managed to survive. In 1985, Porsche’s head of development Helmut Bott earmarked 29 930 Turbo chassis to be turned into 959 prototypes for testing.
The replacement for the SC series came in 1984 as the 911 3.2 Carrera, reviving the Carrera name for the first time since 1977. This was the last iteration in the original 911 series, with all subsequent models featuring new body styling and new brake, electronic, and suspension technologies. Almost the same galvanised body as the SC. Engine was claimed to be 80 per cent new, and the first production 911 to feature an ECU to control the ignition and fuel systems.
As a successor to the Carrera 2.7 MFI, the Carrera 3.0 was fitted with a variation of the 930's engine without a Turbo. During its production period only 3,687 cars were made. The Carrera 3.0 was replaced by the Porsche 911 SC for model year 1978. Between 1976 and 1977, Porsche introduced the Carrera 3.0 with wide rear flares, optional whale-tail, and other luxury options. Built before the ‘911 SC’ it has everything the SC has, and more. It’s a different drive with more power @200bhp; more torque @188 ft/lb @4200rpm and it was 10% lighter too.
Porsche 935

Essentially a Carrera 3.2 with a chopped, more steeply raked windscreen and hood, plus a stripped-out interior. Most had wide Turbo bodies. Porsche insisted that the simple hood was not designed to be 100 per cent watertight. The first Porsche 911 Speedster was built in 1989 and it was the last vehicle with the old 911 body. Three decades passed before the Speedster made a comeback. Had a 3.2 L Aircooled Flat 6 and 2274 were produced for the 1989 model year.
In 1974, Porsche's performance version of the 911 was simply known as the 911 Carrera. It had new bumpers that complied to American regulations and the 2.7-liter engine from the Carrera RS 2.7. Other new features for 1974 included new seats, a full-width rear taillight. The Carrera deleted all the chrome off the car in favor of black window frames, wipers, doorhandles, but chrome could be ordered as an option. In 1976 Porsche replaced the Carrera with a new 3.0 liter variant.
Built so that the factory Rothmans Porsche Rally Team could hit the international stage, the SC RS used the Turbo’s body with fibreglass bumpers and aluminium doors. In Autumn 1983, Porsche presents the 911 SC/RS for motor racing. The engine originates from the 911 SC, with improved performance achieved by the mechanical ball fuel injection, increased compression, the cylinder heads from the 935 and forged pistons. Racing seats are fitted in place of the standard seats.
The Group 4 racer based on the 911 Turbo (930) was called 934 and the Group 5 Porsche was called 935. The first version of the 935 looked similar to the 911 Carrera RSR. The first customers for 935 were Martini Racing and Kremer Racing. The Martini car was a full factory development, while Kremer made its own enhancements already before the first race. By 1977, the 935 was sold as a customer car for these series to race against cars like the BMW CSL.
