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

If you're rebuilding the engine in your Mitsubishi EVO 8 with the 4G63 Turbo, you're likely looking to push its performance limits. This Wiseco 1400 HD piston set is built specifically for those demanding applications. These aren't just replacement pistons; they're forged from 2618 aluminum right here in the USA, giving them improved tensile strength over cast aluminum. This means they can handle the intense heat and pressure that comes with serious performance builds.

Wiseco has packed a lot of thought into these pistons. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which is critical for maintaining compression and preventing blow-by under heavy loads. The fully machined crown ensures consistent combustion chamber volume, and the forced pin oiling helps keep the wrist pins lubricated. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and even quiet things down a bit. These are designed for heavy to severe duty performance applications, so you know they're built tough.

This set includes four pistons, each with an 87.00 mm bore and a -21cc dish volume, along with a 28.87 mm compression height and an 0.866 inch pin diameter. Keep in mind these are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and durability in their 4G63 engine, this Wiseco piston set is a solid choice.
