What is the dome volume, and why does it matter for my build?

The dome volume on these pistons is -12cc. This specification is crucial for determining the final compression ratio of your engine. A negative dome volume typically means the piston crown is dished, which is used to lower compression in boosted or high-performance naturally aspirated applications.

What material are the wrist pins made from?

These pistons come standard with premium chrome moly wrist pins. Manley also offers upgrades to 9310 and Turbo Tuff/DLC alloys on select part numbers for even greater durability in extreme applications.

About this part

Product Details

Manley Performance is well-known for building strong engine components that professional builders trust. This piston set is designed for the Mitsubishi Eclipse GST and GSX, as well as the Eagle Talon, when you're looking to rebuild or upgrade your engine. These pistons feature an 85mm bore and an 88mm stroke, with a -12cc dome volume, which is a key spec for tuning compression ratios in performance builds.

Constructed from domestic 2618 alloy forgings, these pistons offer solid strength for demanding engine builds. They come standard with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt. This attention to detail helps achieve a better ring seal, which translates to more power. The cam and barrel skirt profiles are designed to generate power efficiently while also being gentle on the cylinder walls, contributing to overall engine longevity.

This set includes four pistons, each with exacting ring lands and grooves to further enhance the ring seal. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete engine build, ensure you have all necessary supporting components and refer to manufacturer instructions for proper installation.
