Built so that the factory Rothmans Porsche Rally Team could hit the international stage, the SC RS used the Turbo’s body with fibreglass bumpers and aluminium doors. In Autumn 1983, Porsche presents the 911 SC/RS for motor racing. The engine originates from the 911 SC, with improved performance achieved by the mechanical ball fuel injection, increased compression, the cylinder heads from the 935 and forged pistons. Racing seats are fitted in place of the standard seats.
