Wiseco Mitsu 4G64 w/4G63 Heads 10.5:1 E85 Single Piston

This listing is for a single Wiseco forged piston designed for Mitsubishi 4G64 engines when using 4G63 cylinder heads. It features an 85.50 mm bore and a 10.5:1 compression ratio, making it suitable for E85 fuel applications. This piston is built in the USA from 2618 aluminum, chosen for its improved tensile strength, and includes features like precision ring grooves and an anti-detonation groove to help seal the combustion chamber effectively.

The piston also comes with an ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure. The crown is fully machined for a clean combustion chamber shape, and it includes forced pin oiling to ensure the wrist pin stays well-lubricated under demanding conditions. These pistons are intended for heavy to severe duty performance builds where durability and consistent performance are critical.

Please note that this piston is not CARB approved and cannot be shipped to California. It is designed for serious racers and builders looking for a well-built component for their high-performance engine project.
