CP Pistons Mitsubishi, 2.0L 4G63, CH 1.134, Stroke 88mm, Bore 85.5mm, Rod 156mm, 9.5:1, Heavy Duty

Forged from high-strength aluminum alloy, these Carrillo pistons are built to handle the demands of a performance 4G63 engine. With a bore of 85.5mm and a compression height of 1.134 inches, they are designed to work with an 88mm stroke and a 156mm connecting rod, achieving a 9.5:1 compression ratio. This specific combination is crucial for tuning your engine's power output and efficiency, especially if you're rebuilding the top end for increased performance or durability.

Carrillo is known for its well-built internal engine components, and these pistons are no exception. The heavy-duty construction means they are designed to withstand higher cylinder pressures and temperatures than cast pistons, making them a solid option for modified engines. The 85.5mm bore size is a common specification for many 4G63 builds, offering a good balance between displacement increase and cylinder wall strength. When installing, always refer to the manufacturer's detailed instructions to ensure proper piston ring gap, pin fit, and assembly sequence for optimal performance and longevity.

These pistons are sold as a set and are intended for serious engine builds. While they offer improved strength and performance characteristics, it's important to note that they are not CARB approved and cannot be shipped to California. Ensure your build plans align with emissions regulations in your area.
