CP Piston & Ring Set for Mitsubishi 4G63 1G - 94mm Stroker - Bore (86.0mm) - Size (+1.0mm) - CR (9.0

This kit includes a set of four forged pistons and matching piston rings, specifically sized for the Mitsubishi 4G63 1G engine. These pistons are designed for a 94mm stroker setup with a standard 86.0mm bore, but these particular units are machined to a +1.0mm oversize, meaning they are intended for a cylinder bore measuring 87.0mm. With a compression ratio of 9.0:1, they are a well-built option for rebuilding or upgrading your engine.

CP Pistons are known for their robust construction, and these forged units are no exception. Forging the aluminum provides a stronger, more durable piston compared to cast alternatives, making them a solid choice for performance applications or when rebuilding an engine that demands reliability. The included rings are designed to seal properly against the cylinder walls, contributing to good compression and oil control. This set is intended for the 1G DSM platform, covering the Eagle Talon, Mitsubishi Eclipse, and Plymouth Laser models from 1990 to 1992.

When installing these pistons, ensure your engine block has been properly machined to the correct bore size of 87.0mm. It's always recommended to consult your engine's service manual or a professional mechanic for specific installation procedures and torque specifications.
