Wiseco Mitsubishi EVO X 4B11 Turbo -8cc 86.25mm Bore 8.8 CR HD Forged Piston Kit

If you're building a high-performance Mitsubishi EVO X with the 4B11 turbo engine and pushing its limits, a strong set of forged pistons is essential. This Wiseco Professional Series piston kit is designed for those serious racers and builders who demand the best for heavy to severe duty applications. These aren't your average pistons; they're packed with features to handle the intense pressures and heat of a race-focused build.

Each piston is forged and machined right here in the USA from 2618 aluminum, chosen for its improved tensile strength under extreme conditions. You'll find precision ring grooves, anti-detonation grooves, and other features that help improve ring seal and overall performance. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and even makes operation quieter. The fully machined crown ensures accuracy and optimal combustion chamber shape.

This kit is specifically for the 4B11 turbo engine and features an 86.25mm bore with a compression ratio of 8.8:1, designed to work with a -8cc dish volume. The pistons also feature forced pin oiling for better lubrication. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're serious about your build and need pistons that can withstand the rigors of racing, this Wiseco kit is a solid choice.
