Manley 90-94 Eclipse (6 Bolt 4G63T) 85.5mm +.5mm Over Bore 8.5:1 Dish Piston Set w/ Rings

If you're rebuilding the engine in your 1990-1993 Eagle Talon, especially if you're aiming for more power, this Manley forged piston set is a solid choice. These pistons are designed for the 6-bolt 4G63T engine and come in an 85.5mm bore size, which is a 0.5mm overbore from stock. They feature an 8.5:1 compression ratio, making them suitable for boosted applications where you need a bit more room for boost pressure.

Manley uses their signature 2618 alloy forgings, which are known for being strong and reliable under demanding conditions. The pistons have proven cam and barrel skirt profiles that help them run smoothly against the cylinder walls, reducing wear and noise. You'll also find exacting standards for the ring lands and grooves, which is crucial for getting a good seal with the piston rings, leading to better power output. Each set includes tool steel wrist pins for added durability, and Manley's unique machining process ensures the ring grooves are perfectly square to the piston skirt.

This set comes complete with piston rings, so you have the essential components for your engine build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
