(1991 – 1992) Porsche 911 Turbo 3.3 Coupé – Ultimate Guide
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. That was important, because the 964 Turbo model was the successor to the famous Porsche 930. The 964 Turbo was the end of an era, the last of the single turbo rear-wheel drive 911 Turbos.
Porsche engineers had been working on a new turbo motor for the 964 but were not fully ready in time for launch of the 964 Turbo. The result was that the 964 Turbo was initially released with the proven 3.3-litre turbo engine from the 930 Turbo. A number of updates improved the engine and power increased to 320 bhp at 5,750 rpm and torque was also up to 362 ft/lbs at 4,800 rpm. Stylewise, the 964 911 Turbo had a wider body with significantly more flared wheel housings compared to the 964 Carrera models. The rear wing was basically the same unit as the Turbo 3.3 of the G model. As expected the 964 Turbo a torque monster and was very rapid in a straight line. It was still characterized by lots of turbo lag (common in those days with all single turbo cars).
In 1992, the 3.3 litre Turbo S was introduced. The standard turbo model was modified to produce 381 PS (280 kW; 376 hp) with bigger injectors and more boost and more aggressive camshafts and with a lightweight interior and limited “creature comforts” the Turbo S was one of the fastest cars on the road. Porsche released the 964 Turbo 3.6 in January, 1993, now featuring a KKK K27 turbocharged version of the 3.6 litre M64 engine developing 360 PS (355 bhp; 265 kW) at 5,500 rpm and 520 N⋅m (384 lbf⋅ft) at 4,200 rpm of torque, produced only for model year 1993/1994.
