Wiseco 1400 HD Mitsu EVO 8/9 4G63 Turbo 100mm Stroker -21cc 86.5 Bore 9.1 CR Piston Kit

What you get in this kit are four Wiseco 1400 HD forged pistons, designed specifically for the Mitsubishi 4G63 engine found in the EVO 8 and 9. These aren't just any pistons; they're built for serious racing and heavy-duty performance builds. The kit includes the pistons, premium rings, and pins needed to get them installed.

Wiseco forges these pistons from 2618 aluminum right here in the USA, which gives them improved tensile strength for handling the high stresses of a performance engine. They feature precision ring grooves, an anti-detonation groove, and other features to ensure a solid seal. You'll also find an ArmorGlide skirt coating, which helps reduce friction and resist seizure, making for quieter operation and better durability. The fully machined crown and forced pin oiling are details that show these are made for severe duty applications.

This piston set is intended for builders who are pushing their 4G63 engines hard. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete engine build, you'll want to ensure you have all the necessary supporting components and follow the manufacturer's installation guidelines carefully.
