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 a prime example, built specifically for demanding builds like the Mitsubishi Evo 8 with its 4G63 turbo engine. If you're putting together a serious race engine or a heavy-duty street build, these pistons are designed to handle the stress and heat that come with pushing your engine hard.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength over cast aluminum. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal, which is crucial for maintaining compression and preventing blow-by under high boost. The crown is fully machined for accuracy, and they include forced pin oiling to ensure the wrist pins stay well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, even in severe duty conditions.

This kit includes a set of four pistons, each with an 86.25 mm bore and a -14cc dish. Remember, these are intended for serious performance builds and are not CARB approved, so they cannot be shipped to California. If you're rebuilding the top end of your Evo 8's 4G63 engine for racing or extreme performance, this Wiseco piston set is a solid option to consider.
