In 1970, the 4G32 was introduced, and it displaces 1.6 L (1,597 cc).
It is an eight-valve SOHC design with an aluminium head and iron block.
The engine has five main bearings, a cross flow head and a single down draught carburetor.
Firing order is 1-3-4-2.
The GSR versions used two twin-barrel Mikuni-built Solex carburetors for a total of 110 hp (82 kW) (SAE).

A version with an early iteration of Mitsubishi's MCA lean-burn system (MCA-IIB), fulfilling the intermediate Japanese exhaust regulations for 1975, was called G32A. This was built for less than one year, as the new MCA engine arrived in November 1975.
Those with the later, cleaner yet, "MCA-Jet" system were called G32B. Later, the G32B also came in a fuel injected, turbocharged model.
For competition, a version of the 4G32 engine was made with a DOHC eight-valve cylinder head, and fitted with two twin-choke 40 mm (1.6 in) Solex sidedraft carburettors.
