Wiseco Mitsubishi EVO X 4B11 Turbo -8cc 87mm Bore 8.8 CR HD Forged Piston Kit

If you're building a high-performance Mitsubishi EVO X with the 4B11 turbo engine, Wiseco's Professional Series forged piston kit is a solid choice for serious racers and builders. These pistons are designed to handle the demands of heavy to severe duty race applications, giving you the confidence to push your engine's limits. They are forged and machined in the USA from 2618 aluminum, a material known for its improved tensile strength, making them well-suited for high-stress environments.

Wiseco has packed these pistons with features aimed at durability and performance. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The fully machined crown ensures accuracy, and the forced pin oiling system helps keep the wrist pins lubricated under extreme conditions. Additionally, the ArmorGlide skirt coating helps reduce friction and resist seizure, while also contributing to quieter operation. This kit is designed to be a direct replacement for your stock pistons, with an 87mm bore and a -8cc dish that results in a 8.8:1 compression ratio.

This kit includes a set of four pistons, along with premium rings to ensure proper sealing. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and reliability in their 4B11 turbo build, this Wiseco kit offers a well-built solution.
