Wiseco 1400 HD Mitsu EVO 8 - 4G63 Turbo -21cc Piston Shelf Stock Kit

If you're rebuilding the engine for your 1993-1999 Mitsubishi Eclipse, especially for a performance build, Wiseco's Professional Series forged pistons are a solid choice. These aren't your average pistons; they're crafted from 2618 aluminum, which gives them improved tensile strength over standard aluminum. This means they can handle the intense pressures and heat found in heavy to severe duty race applications. Wiseco machines these pistons in the USA, ensuring precision in every detail.

You'll find features like precision ring grooves, anti-detonation grooves, and extra sealing features designed to improve ring seal and durability under extreme conditions. The fully machined crown is ready for whatever you throw at it, and the forced pin oiling helps keep the wrist pins lubricated. Plus, they come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and even makes operation quieter, which is a nice bonus when you're pushing your engine hard.

This kit is designed for the 4G63 engine and includes four pistons with a bore size of 87.50 mm and a -21cc dish volume. They are built to withstand the demands of serious racing and performance builds. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
