About this part

Product Details

This Manley piston set includes everything you need to get your 4G63T engine rebuilt: four forged pistons, a complete set of rings, and wrist pins. These are designed for the 2003-2006 Mitsubishi Lancer Evolution VIII and IX, featuring an 86.5mm bore size, which is a +1.5mm overbore for a 100mm stroke application, and a dish volume that results in a compression ratio of 8.5:1. This setup is ideal for building a robust engine capable of handling significant power.

Manley uses domestic 2618 alloy forgings for these pistons, known for their strength and ability to perform under demanding conditions. The pistons feature proven cam and barrel skirt profiles, which help generate power efficiently while minimizing wear on your cylinder walls. The ring lands and grooves are machined to strict standards to ensure a tight seal, which is crucial for maximizing power output. For added durability, these pistons come with premium chrome moly wrist pins. Manley's unique manufacturing process allows them to machine the skirt and ring grooves in a single operation, ensuring the grooves are perfectly square to the skirt for optimal performance.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your Evo 8 or 9 and looking for a solid foundation for a high-performance engine, this Manley piston set is a well-built option.
