Porsche introduced the 964 Turbo model in March, 1990 as the successor to the 930. Unfortunately, they hadn’t had the necessary time to develop a turbocharged version of the 3.6 liter M64 engine, and chose to re-use the 3.3 liter 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 hp @ 5750 rpm. A total of 3,660 of the 964 Turbos were built.
In 1992 the 3.3 litre Turbo S was introduced. With a power of 381 PS (280 kW; 376 hp) and with a lightweight interior and limited “creature comforts” the Turbo S was one of the fastest cars on the road. With lowered suspension, a front strut brace and manual steering, the Turbo S was geared to performance. About 80 cars were produced during the only year of production.
Porsche released the 964 Turbo 3.6 in January, 1993, now featuring a turbocharged version of the 3.6 liter M64 engine and producing 360 hp @ 5500 rpm, the 3.6 liter powered Turbo was produced only for model year 1993/1994, with fewer than 1,500 of them produced in total, making it one of the rarest and most sought after Porsches produced since the 959.
At the end of 964 production in 1994 the Porsche factory had some 90 Turbo chassis left. These were all transferred to Porsche Exclusiv and built as the very special Turbo 3.6S. The Turbo 3.6S was available either with the traditional 964 Turbo 3.6 body, or with the exclusive Slant nose option.
