CP Piston & Ring Set for Mitsubishi 1st Gen 4G63T - Bore (86.0mm) - Size (+1.0mm) - Compression Rati

If you're rebuilding the engine in your 1990-1992 Eagle Talon, especially if you're aiming for more power or need to replace worn components, a set of high-performance pistons like these from CP Pistons is a solid choice. These are forged pistons, which means they start as a solid block of aluminum alloy that's heated and hammered into shape under immense pressure. This process creates a much stronger and more durable piston than cast pistons, making them ideal for engines that see hard use or are modified for increased performance. This particular set is designed for the 4G63T engine found in the first generation of these cars.

This set features a bore size of 86.0mm, which is a +1.0mm oversize from the factory specification. This is common when an engine needs to be bored out to clean up cylinder walls that have been damaged by wear or overheating. The included rings are specifically matched to this bore size and piston design. CP Pistons is well-known for producing well-built engine components that can handle the demands of performance applications. When installing these, ensure your machine shop has accurately bored and honed the cylinders to the correct size and finish for optimal ring seal and longevity.

This kit includes the pistons and the necessary rings to complete the installation. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and consult with your engine builder to ensure all specifications are met for a successful rebuild.
