1992 Porsche 911 Turbo Test Drive
In spite of the turmoil that resulted in the Turbo we actually received, the North American car still had a potent 320 hp at 5750 rpm with emissions equipment, which was made possible by the use of the sport kit previously available as an option on earlier 3.3-liter 930s. The kit included a larger turbocharger and intercooler. Torque was rated at 332 lb-ft at 4500 rpm. Redline was 6900 rpm. CIS/K-Jetronic was retained because it was a known quantity and cheaper to implement than developing a modern, computerized engine management system. However, the system was modified to run with an electronic control unit (ECU), which allowed more precise changes in ignition timing.
