Product Details
This set gives you a complete package for upgrading your Mitsubishi 4G63 or 4G63T engine. You get four forged pistons, each with an 87mm bore and a -8cc dome dish, plus the necessary rings and tool steel wrist pins to get them installed. These pistons are designed to be 2.0mm larger than stock, which is a common size when rebuilding or modifying these popular 4-cylinder engines. They're built to handle the demands of performance builds, whether you're aiming for more power or rebuilding after significant mileage.
Manley uses domestic 2618 alloy forgings for these pistons, which are known for being strong and reliable under pressure. The cam and barrel skirt profiles are carefully shaped to help the piston move smoothly in the cylinder, reducing wear on the cylinder walls while still allowing the engine to make good power. They also pay close attention to the ring lands and grooves, ensuring a tight seal with the piston rings. This precise machining helps prevent blow-by and contributes to better overall engine performance. The included wrist pins are made from tool steel, adding to the durability of the assembly.
These pistons are a solid choice for anyone looking to rebuild or enhance their 4G63 or 4G63T engine. They fit a range of vehicles, including models like the Mitsubishi Eclipse, Lancer, and Eagle Talon from the mid-90s to early 2000s. It's important to note that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
