What is the compression ratio of this piston set?

This Mahle piston set is designed to achieve a 9.0:1 compression ratio. This is calculated based on the piston's -10cc dish volume, the 85.50mm bore, and the 88.0mm stroke when used with a 150mm connecting rod.

What material are these pistons made from?

These pistons are forged from 2618 aluminum. This material is chosen for its strength and ability to withstand high temperatures and pressures, making it suitable for performance engine builds.

Are these pistons compatible with all 4G63 engines?

This set is specifically designed for the 4G63 2.0L engine found in various Mitsubishi models from 1993 to 2009. It is important to confirm that your engine's specifications match the 85.50mm bore, 88.0mm stroke, 150mm rod length, and 22mm wrist pin requirements.

Product Details

Starting with a 22mm wrist pin and a -10cc dish volume, this Mahle MS Piston Set is built for the demanding needs of the Mitsubishi 4G63 2.0L engine found in models from 1993 through 2009. These pistons are forged from 2618 aluminum, a strong material known for its durability and ability to handle high temperatures and pressures, making them a solid choice for performance builds. The set includes pistons with an 85.50mm bore and an 88.0mm stroke, designed to work with a 150mm connecting rod, all contributing to a calculated 9.0:1 compression ratio. This specific compression ratio is a notable improvement over stock, offering a good balance for increased power without requiring extreme fuel modifications.

Each piston weighs in at 315g, which is a reasonable weight for a forged piston of this caliber, helping to keep reciprocating assembly balance in check. The -10.0cc dish is a key design element that helps achieve the 9.0 CR, providing a more efficient combustion chamber for enhanced power output. Mahle has a long-standing reputation for producing well-built engine components, and this piston set continues that tradition, offering a reliable foundation for engine rebuilds or performance upgrades. It's important to note that these pistons are not CARB approved and cannot be shipped to California.

When undertaking an engine build with these pistons, ensure you have the correct connecting rods and crankshaft to achieve the specified stroke and rod length. Proper balancing of the rotating assembly is also crucial for engine longevity and smooth operation. This set is designed as a complete kit of four pistons, ready for installation by a qualified mechanic.
