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

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance builds where strength and durability are key. The 2618 alloy offers improved tensile strength over other aluminum types, making it a solid choice for engines that see heavy use. This particular piston is designed for the Mitsubishi 4G63 turbo engine, featuring a -21cc dish for specific compression ratio targets.

Wiseco packs a lot of smart design into these pistons. You'll find precision ring grooves that help ensure a good seal, along with anti-detonation grooves and other features to improve ring seal under pressure. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and keep things quieter during operation. The fully machined crown and forced pin oiling are details that matter when you're pushing an engine hard.

These pistons are intended for heavy to severe duty applications, meaning they're built to handle the kind of stress that comes with performance tuning and racing. If you're rebuilding the top end of your 1993-1999 Eclipse, Eagle Talon, or Plymouth Laser, or even a 2003-2006 Lancer with the 4G63 turbo, these Wiseco pistons are a well-built option to consider for a robust engine build.
