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

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series forged piston kit is built for serious racers and builders who need top-tier performance and durability from their engine. Designed for heavy to severe duty race builds, these pistons are engineered to remove your limits.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The fully machined crown is ready for your build, and forced pin oiling helps keep things lubricated. Plus, the ArmorGlide skirt coating helps resist seizure, reduces friction, and contributes to quieter operation.

This kit is specifically designed for Mitsubishi 4G64 engines using 4G63 heads, with a bore size of 86.50 mm and a compression height of 35.00 mm. The kit includes four pistons and features a 10.5:1 compression ratio, making it suitable for E85 fuel. Please note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
