Wiseco 1400 HD Mitsu EVO 8 4G63 Turbo -14cc 86.25mm Bore Piston Kit - Set of 4

If you're rebuilding the heart of your Mitsubishi 4G63 Turbo engine for serious performance, a set of Wiseco 1400 HD pistons is a solid choice. These aren't your average pistons; they're built from the ground up for heavy to severe duty race applications, meaning they can handle the kind of stress that comes with pushing your engine hard. The 86.25mm bore size is specific for certain builds, and the -14cc dish helps set your compression ratio for boosted performance.

Wiseco forges these pistons from 2618 aluminum right here in the USA, which gives them improved tensile strength for durability under high loads. You'll find precision ring grooves, anti-detonation grooves, and features designed for better ring seal, all contributing to a more reliable engine. They also come with an ArmorGlide skirt coating that helps reduce friction and noise, and resists seizure, which is crucial when you're running your engine hard. The fully machined crown and forced pin oiling are details that show these pistons are made for demanding use.

This set includes four pistons, ready to be installed in your 4G63 Turbo. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a build that needs to withstand significant abuse and deliver consistent power, these Wiseco pistons are a well-built option.
