Wiseco 1400 HD Mitsubishi Evo 8 - 4G63 Turbo -21cc Piston Shelf Stock Kit

If you're building a serious performance engine for your Mitsubishi Evo 8 with the 4G63 turbo, Wiseco's 1400 HD Professional Series piston kit is a solid choice. These aren't just off-the-shelf pistons; they're built from the ground up for demanding race applications where reliability and strength are paramount. Each piston is forged and machined right here in the USA from 2618 aluminum, a material known for its improved tensile strength, making it well-suited for the high stresses of a performance turbo engine.

Wiseco has packed a lot of thoughtful features into these pistons. You'll find precision ring grooves designed for better seal, anti-detonation grooves to help prevent pre-ignition, and forced pin oiling to keep the wrist pins properly lubricated under extreme conditions. The piston crowns are also fully machined, and they feature an ArmorGlide skirt coating. This coating helps reduce friction, makes operation quieter, and offers resistance to seizure, which is crucial when you're pushing your engine hard.

This kit is designed for heavy to severe duty performance builds, meaning they're made to handle the kind of abuse that comes with serious racing. The -21cc dish volume is specific to certain engine builds, so make sure it matches your compression ratio targets. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust piston set that's ready for the track, this Wiseco kit is a well-built option.
