O Mitsubishi 4G63 e 4G64 are part of the robust Sirius engine family, widely used in both passenger cars and light commercial vehicles. The 8-valve SOHC variants are simpler and more rugged compared to their 16-valve DOHC counterparts, ideal for markets valuing easy maintenance and high torque at low RPM.
These cylinder heads are made of liga de alumínio, with cast iron blocks, typically paired with a correia dentada, mechanical rocker arms, e multi-point fuel injection (MPI) or carburetors depending on the application.
