Wiseco Mitsu 4G63 2.0L 10.5:1 CR E85 Piston Shelf Stock Kit

If you're building a high-performance Mitsubishi 4G63 engine, especially one designed to run on E85 fuel, this Wiseco Professional Series piston kit 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 severe duty race applications. The kit includes four pistons, each with an 86.00 mm bore and a 10.5:1 compression ratio, which is a popular setup for E85 builds.

Wiseco has put a lot of thought into the details with these pistons. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is crucial for both power and engine longevity under high stress. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and even makes the engine run a bit quieter. The fully machined crown and forced pin oiling are further enhancements that speak to their design for serious racing and heavy-duty use.

This kit is designed for serious racers and builders who are pushing their engines hard. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
