Wiseco Mitsu 4G64 w/4G63 Heads 10.5:1 E85 Piston Shelf Stock Kit

If you're building a high-performance Mitsubishi 4G64 engine using 4G63 heads and planning to run E85 fuel, this Wiseco piston set is a solid choice. These pistons are forged from 2618 aluminum, a material known for its improved tensile strength, making them well-suited for the demands of serious racing and severe duty applications. The 10.5:1 compression ratio is specifically tuned for E85 fuel, helping you get the most out of this potent fuel source.

Wiseco has packed these pistons with features to ensure durability and performance. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The fully machined crown and forced pin oiling contribute to reliable operation under extreme conditions. Additionally, the ArmorGlide skirt coating helps reduce friction and noise, while also resisting seizure, which is crucial when pushing an engine hard.

This kit includes four pistons, each with an 87.00 mm bore and a 35.00 mm compression height, and uses a 0.8661 inch pin diameter. They are designed and machined in the USA. Please note that these pistons are not CARB approved and cannot be shipped to California.
