CP Piston & Ring Set for Mitsubishi 2nd Gen 4G63T - Bore (86.0mm) - Size (+1.0mm) - CR (9.5:1)

CP Pistons is known for making strong, well-built internal engine components for performance applications. If you're rebuilding or upgrading the engine in your 1993-1999 Mitsubishi Eclipse, Eagle Talon, Mitsubishi Lancer, or Plymouth Laser, this forged piston and ring set is built to handle more power. This set is specifically for the 4G63T engine, a popular choice for tuners looking to increase horsepower.

This particular set features an 86.0mm bore, which is 1.0mm oversize from the factory specification. This is often done when an engine needs to be bored out due to wear or to increase displacement slightly. The compression ratio is set at 9.5:1, a common target for modified turbocharged engines that balances street drivability with performance potential. Forged pistons like these are significantly stronger than cast pistons, making them a solid choice for engines that will see higher boost levels or more aggressive tuning. They are designed to withstand the increased cylinder pressures and temperatures associated with performance modifications.

When installing this set, remember that the 1.0mm oversize means your engine block will need to be machined to match these pistons. It's always recommended to consult with a professional engine builder or refer to the manufacturer's detailed installation instructions to ensure proper fitment and assembly. This set includes the pistons and rings needed to rebuild your engine's cylinders. Please note that this part is not CARB approved and cannot be shipped to California.
