Wiseco 1400 HD Mitsubishi Evo 8 - 4G63 Turbo -14cc Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components, especially for high-performance applications. This Professional Series piston set is built for serious racers and builders who demand top-tier durability and performance from their Mitsubishi Evo 8's 4G63 Turbo engine. These aren't your average pistons; they're designed from the ground up to handle the stress of heavy to severe duty race builds, giving you the confidence to push your engine to its limits.

Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for withstanding the high pressures and temperatures found in performance engines. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, ensuring efficient combustion and preventing detonation. The fully machined crown contributes to precise combustion chamber volume, and forced pin oiling helps keep the wrist pins lubricated under extreme conditions. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, adding another layer of durability and refinement to your build.

This set includes four pistons, each with an 85.25 mm bore and a -14cc dish. They feature a 35.00 mm compression height and a 0.8661-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're rebuilding your top end for serious competition, these pistons are a solid option for building a robust and reliable engine.
