The 911 Turbo was put into production in 1975. While the original purpose of the 911 Turbo was to gain homologation for the 1976 racing season, it quickly became popular among car enthusiasts. Ernst Fuhrmann adapted the turbo-technology originally developed for the 917/30 CAN-AM car and applied it to the 3.0 litre flat-six used in the Carrera RS 3.0, thus creating what Porsche internally dubbed as the 930. Total power output from the engine was 260 PS (191 kW; 256 hp) at 5,500 rpm and 329 N⋅m (243 lb⋅ft) of torque at 4,000 rpm, much more than the standard Carrera it was based on. In order to ensure that the platform could make the most of the higher power output, a revised suspension, larger brakes and a stronger gearbox became part of the package. The 930 was upgraded with a 3.3L engine for model year 1978.
