Carrera 3.2 (1984–1989)
The replacement for the SC series came in 1984 as the 911 3.2 Carrera, reviving the Carrera name for the first time since 1977. This was the last iteration in the original 911 series, with all subsequent models featuring new body styling and new brake, electronic, and suspension technologies.
A new higher-displacement engine, a 3.2-litre horizontally opposed flat 6-cylinder unit, was utilized. At the time Porsche claimed it was 80% new. The new swept volume of 3,164 cc was achieved using the 95 mm (3.7 in) bore (from the previous SC model) combined with the 1978 Turbo 3.3 crankshaft’s 74.4 mm (2.9 in) stroke. In addition, higher domed pistons increased the compression ratio from 9.8 to 10.3:1 (9.5:1 for the US market).
New inlet manifold and exhaust systems were fitted. The 915 transmission was carried over from the SC series for the first three model years. In 1987, the Carrera got a new five-speed gearbox sourced from Getrag, model number G50 with proven BorgWarner synchronizers. This slightly heavier version also featured a hydraulically operated clutch.
