What is the compression ratio with these pistons?

These pistons are designed with a dish top that aims for a compression ratio between 10.0:1 and 10.5:1. The final compression ratio will depend on the specific cylinder head volume used in your engine build.

Are these pistons suitable for a high-performance or boosted engine?

Yes, these are forged pistons made from 2618 alloy, which is known for its superior strength and durability. The design and materials are well-suited for engines that experience higher stresses from performance modifications or forced induction.

What is included with this piston set?

This set includes the four pistons, piston rings, and premium chrome moly wrist pins. It is a complete set ready for installation into your engine.

About this part

Product Details

If you're rebuilding the engine in your 1993-1999 Mitsubishi Eclipse, Lancer Evolution VIII/IX, or Eagle Talon, a set of high-performance pistons like these from Manley is a critical component. These are forged pistons, meaning they start as a solid block of aluminum that's heated and hammered into shape, making them much stronger and more durable than cast pistons. This strength is essential for engines that are pushed hard, whether for daily driving or track use.

Manley uses their signature 2618 alloy for these pistons, which is known for its superior strength and ability to handle high temperatures and pressures. They've also incorporated proven cam and barrel skirt profiles. Think of the skirt profile as how the piston is shaped on its sides; these specific shapes help the piston move smoothly within the cylinder, reducing friction and wear on the cylinder walls while still allowing the piston to generate substantial power. The ring lands and grooves are machined to very strict standards, which is key for getting a good seal with the piston rings. A good ring seal means better compression, less oil getting into the combustion chamber, and ultimately, more power from your engine.

This set is specifically sized at 86.0mm with a +1.0mm over size, and features a dish top designed for a 10.0 to 10.5:1 compression ratio, depending on your cylinder head volume. They come complete with premium chrome moly wrist pins and are ready to be installed. Remember, 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.
