By the mid 1970's the Porsche 911 had already reached legendary status, both on and of the track, and since the car's launch in 1965 the Stuttgart factory's engineers had found ways to squeeze more power from the 2 to 3 litre flat six cylinder engines. During this time the 911's dramatic development had much to do with the frantic racing programme that was used to expand the range, no other car can claim such a linier heritage to racing as the 911.
The road cars benefited as well as the race cars of this era, hailing a new dawn in motoring and perhaps one of the most famous marriages in modern sports car production, that of the Porsche 911 and the Turbo charger. First introduced in 1975 the production 911 Turbo was directly derived from the cars used in endurance racing and used a 3 litre engine with a 4 speed gearbox. These early examples were quite crude although very powerful, and were superceeded in 1977 by the more familiar 3.3 litre version produced until 1989. With a larger intercooler and better brakes this Turbo was far more refined, however it had not lost the performance edge with a healthy 300 bhp on tap the car still had that legendary turbo kick.
The result was nothing more than staggering as the car sold in the thousands, an instant classic it was the definitive sports car of its age. So in 1989 when Porsche announced the end of the 'true' 911 to make way for the new 964 launch in 1990 a special commission of 50 Turbos were to be built with standard features previously only available as factory optional extras. This was to include rear wheel air intakes, skirts and front spoiler (and oil cooler),reminiscent of the 935 Le Mans sports racing car. But more noticeably was the fitment of a limited slip diff and an extra 30bhp, making it the most powerful limited edition 911 Turbo ever built.
