Manley 90-94 Eclipse (6 Bolt 4G63T) 85.5mm +.5mm Over Bore 9.0:1 Dish Piston Set w/ Rings

Manley Performance is well-known for building strong engine components that professional builders trust. If you're working on the engine for your 1990-1993 Eagle Talon, especially if you're aiming for improved performance, this set of forged pistons is a solid choice. These pistons are designed to replace your stock ones with a slightly larger bore size of 85.5mm, which is 0.5mm over the standard size, and feature a dish shape that results in a 9.0:1 compression ratio. This setup is common when rebuilding or upgrading the 4G63T engine found in these cars.

These pistons are made from domestic 2618 alloy forgings, a material chosen for its strength and ability to handle the demands of a performance engine. They also feature proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still allowing the engine to make good power. Manley pays close attention to the details, ensuring the ring lands and grooves are machined to strict standards. This precise machining is key for getting a good seal with the piston rings, which directly impacts how much power your engine can produce and how efficiently it runs. The set includes tool steel wrist pins for added durability, and the unique fixturing Manley uses allows them to machine the skirt and ring grooves in one operation, ensuring they are perfectly square to each other.

This piston set is designed as a direct replacement for your 1990-1993 Eagle Talon, Mitsubishi Eclipse, or Plymouth Laser equipped with the 6-bolt 4G63T engine. It comes complete with the necessary piston rings to get your engine back together. Please note that these pistons are not CARB approved and cannot be shipped to California.
