About this part

Product Details

This product includes a complete set of eight forged pistons from CP Pistons, designed for Mercedes M177 and M178 engines. These pistons feature an 83mm bore and a 10.5:1 compression ratio, making them a solid choice for engine builds where improved performance and durability are key goals. CP Pistons is well-known for their high-performance internal engine components, and this set is built to handle the demands of a performance-oriented engine.

Forged pistons are significantly stronger than cast pistons, which is crucial for engines that see higher cylinder pressures and temperatures. This strength allows for more aggressive tuning and sustained performance. The 10.5:1 compression ratio is a common target for performance builds, offering a good balance between power output and pump fuel compatibility, though specific tuning will dictate optimal fuel requirements. The 83mm bore is the standard size for these engines, ensuring a direct fit for rebuilding or upgrading your M177 or M178 powerplant. 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 all the necessary supporting components, including appropriate connecting rods, bearings, and a properly balanced crankshaft. Proper ring gap setting and cylinder wall preparation are critical for optimal performance and longevity. Always refer to the manufacturer's installation instructions for precise specifications and recommended procedures.
