CP Piston & Ring Set for Mitsubishi 2nd Gen 4G63T 94mm Stroker - Bore (85.5mm) - Size (+0.5mm) - Com

This kit includes a set of four forged pistons and matching piston rings, specifically designed for 4G63T engines in Mitsubishi Eclipse, Eagle Talon, and Plymouth Laser models from the mid-90s, as well as later Mitsubishi Lancers. These pistons are built for a 94mm crankshaft stroke and come at an 85.5mm bore size, which is a +0.5mm oversize from the standard bore. This setup is ideal for enthusiasts looking to build a stroker engine, aiming for increased displacement and improved performance from their 4-cylinder powerplant.

CP Pistons is known for making well-built engine components, and these pistons are no exception. They are forged from high-strength aluminum alloy, a material chosen for its ability to withstand the higher cylinder pressures and temperatures found in performance or modified engines. The 85.5mm bore size means these are intended for engines that have already been bored out to accommodate this larger diameter, often as part of a performance rebuild. The included rings are crucial for sealing the combustion chamber and managing oil, ensuring proper engine function with the new piston dimensions. This set is a solid option for anyone rebuilding or significantly upgrading their 4G63T engine.

When installing these pistons, remember they are an oversize part, meaning your engine block will need to be machined to the specified 85.5mm bore. It's also important to note that this part is not CARB approved and cannot be shipped to California. Always consult your engine builder or a professional mechanic for specific installation procedures and compatibility with other engine components in your build.
