Wiseco 1400 HD Mitsu EVO 8 - 4G63 Turbo -14cc 85.25mm Bore 8.5 CR Piston Shelf Stock Kit

If you're building a serious performance engine for your Mitsubishi 4G63 Turbo, like in an EVO 8, these Wiseco Professional Series pistons are a solid choice. They're forged from 2618 aluminum right here in the USA, which gives them improved tensile strength for handling the demands of heavy or severe duty racing. This isn't just a basic piston; Wiseco packs them with features like precision ring grooves, anti-detonation grooves, and other ring seal improvements to ensure everything works together smoothly under high stress.

You'll also notice the ArmorGlide skirt coating. This isn't just for looks; it helps reduce friction, makes operation quieter, and resists seizure, which is critical when you're pushing your engine hard. The fully machined crown and forced pin oiling are also details that show these pistons are made for performance applications where reliability is key. They come with premium rings, so you're getting a well-matched set ready for a demanding build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for competition use and are a significant upgrade for anyone serious about their 4G63 engine build.
