1975 LA Lancer Buildup - 4G35 Engine Specs
The 4G35 is another much sort after engine in Australia for people modifying early Mitsubishi's. The reasoning behind this is that whilst most of the components are the same as the 4G33 (1.4 litres) and 4G32 (1.6 litres) engine factory fitted, it has a larger capacity of 1.7 litres.
As I have managed to obtain a copy of the workshop manual for the Galant GTO, I have the factory specifications for two of the different 4G35 engines as fitted to the 1970-71 Galant GTO.
The factory specifications are below, all specifications in brackets are for the GS motor, which was more powerful then the standard motor.:
