Ford Pinto
Offered with an inline-4 engine and bucket seats the Pinto's mechanical design was conventional, with unibody construction, a longitudinally mounted engine in front driving the rear wheels through either a manual or automatic transmission and live axle rear end. Suspension was by unequal-length control arms with front coil springs; the live rear axle was suspended on leaf springs. The rack and pinion steering had optional power assist, as did the brakes.
Ford Pinto engine
In the beginning of the 1980s, Cosworth developed a 16-valve performance head conversion for the Pinto engine. This was seen by a Ford executive who asked Cosworth to develop it with a turbo for use in the new Ford Sierra RS Cosworth.
The engine is therefore based on a modified Pinto block topped with the Cosworth-developed alloy head and Garrett turbo.
