Engine based on modified 3.6 litre 964 unit. Speedline wheels with big red brake calipers. Lessons learned in the Carrera Cup series proved the reliability of the new 3.6-litre engine. An additional three millimetres on the bore and two millimetres on the stroke, resulted in an increase in capacity of 300 cc. Combined with the turbo optimised cylinders, pistons and crank train, and an increase in the compression ratio from 7.0 to 7.5:1, this helped to boost power to 360 bhp. Torque was increased significantly to 520 Nm at 4200 rpm, up from 450 Nm at 4500 rpm in the earlier car.

The 1990 season was the first season that saw the 911-based model become the pillar on which the Porsche Carrera Cup series has been established.
