Wiseco 1400 HD Mitsu EVO 8 4G63 Turbo -21cc 86.25 Bore +.050 Oversize 8.7 CR Piston Shelf Stock Kit

This kit gets you four Wiseco 1400 HD pistons, ready to go into your Mitsubishi 4G63 Turbo engine. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, giving them improved tensile strength for demanding builds. They come with precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which is crucial for keeping boost in check and power consistent.

Wiseco also applies their ArmorGlide skirt coating to these pistons. This coating helps resist seizure, reduces friction for smoother operation, and contributes to quieter running, even under heavy load. The fully machined crown and forced pin oiling are details that show these pistons are built to handle severe duty performance applications. This set is specifically sized at 86.25mm bore, which is +.050 inch oversize, and features a -21cc dish for an 8.7:1 compression ratio, making them a solid choice for serious engine builders.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders working on a high-performance 4G63 Turbo, these Wiseco pistons offer a well-built foundation for a powerful and durable engine.
