Manley 03-06 Evo 8/9 (7 Bolt 4G63T) 86mm +1mm Over Bore 8.5:1 Dish Pistons w/ Rings

If you're rebuilding the engine in your 1993-1999 Mitsubishi Eclipse, Eagle Talon, Plymouth Laser, or 2003-2006 Mitsubishi Lancer, these Manley Performance forged pistons are a solid choice. These are designed for the 7-bolt 4G63T engine, coming in at 86mm with a +1mm overbore and a dish shape that results in an 8.5:1 compression ratio. This setup is ideal for building a more robust engine that can handle increased boost levels and power output compared to stock.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to withstand high temperatures and pressures. The pistons feature proven cam and barrel skirt profiles, which help them generate power efficiently while also being gentler on your cylinder walls during operation. You'll also find exacting standards applied to the ring lands and grooves, which is crucial for achieving a good seal with the piston rings, leading to better compression and more power. Each set includes premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt for optimal performance.

This set includes the pistons and rings needed for your rebuild. Please note 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.
