CP Piston & Ring Set for Mitsubishi 4G63 1G 100mm Stroker - Bore (85.5mm) - Size (+0.5mm) - Compress

This is a CP Pistons forged piston and ring set specifically for the Mitsubishi 4G63 engine, designed for 1G models with a 100mm stroker setup. It's built for a bore of 85.5mm and comes at a +0.5mm size, meaning these pistons are 0.5mm larger than standard bore size to account for machining or specific build requirements. If you're rebuilding the top end of your 1990-1992 Eagle Talon, 1990-1992 Mitsubishi Eclipse, or 1990-1992 Plymouth Laser with a stroker kit, these pistons are a key component for achieving your performance goals.

CP Pistons is known for making well-built internal engine components, and this set is no exception. Forged from high-strength aluminum alloy, these pistons are designed to withstand the increased stress and heat associated with higher compression and stroker applications. The set includes the pistons and the necessary rings, all sized to fit the specified bore and stroke combination. This means you get a matched set ready for installation after your engine block has been properly machined to the correct dimensions. The +0.5mm sizing is important; it indicates these are intended for an engine block that has been bored out to 85.5mm, plus an additional 0.5mm, which is common when rebuilding or modifying engines for increased displacement or to clean up cylinder walls.

When undertaking a stroker build, especially with a performance-oriented engine like the 4G63, using high-quality internal components is crucial for reliability and power. This piston set is a solid option for enthusiasts looking to maximize the performance of their engine. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper fitment and assembly procedures.
