Wiseco Mitsubishi Lancer EVO 8 - 4G63 Turbo Piston Kit

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and high-performance engine builds. The 2618 alloy offers improved tensile strength, making these pistons a solid choice when you're pushing your 4G63 turbo engine to its limits. Each piston is machined in the USA to exacting standards, ensuring a precise fit and reliable performance under heavy or severe duty conditions.

Wiseco has included several features to enhance durability and performance. The pistons have precision ring grooves, an anti-detonation groove, and additional features designed to improve ring seal, which is crucial for maintaining compression and power. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and contribute to quieter operation, all important factors when building a high-output engine.

This set includes four pistons, each with a bore size of 85.50 mm and a compression height of 35.00 mm. The pin diameter is 0.866 inches. The fully machined crown and forced pin oiling further contribute to the robust design. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're rebuilding your top end for serious competition, this set is a well-built option designed for the task.
