Product Details

Mahle MS Piston Set for Porsche 964 and 993 Turbo models. This set is designed for engine rebuilds where increased displacement and performance are the goal. The pistons feature a 102mm bore, which is larger than stock, and are designed to work with a 76.4mm stroke crankshaft and a 127mm connecting rod. The 23mm wrist pin diameter is standard for many performance applications.

These pistons are forged from high-strength aluminum alloy, a common practice for performance engine components because it offers a strong yet lightweight solution. This forging process creates a denser, more durable piston capable of handling the higher cylinder pressures and temperatures found in turbocharged engines. The 22.6cc dish volume combined with the bore and stroke results in a 9.3:1 compression ratio, which is a popular choice for turbocharged applications, offering a good balance between power and reliability. This set includes six pistons, enough for a complete six-cylinder engine.

It's important to note that this piston set is not CARB approved and cannot be shipped to California. For installation, ensure you consult the manufacturer's detailed specifications and recommended assembly procedures, as precise measurements and clearances are critical for optimal performance and engine longevity.
