What is the compression ratio of this piston set?

This Mahle MS piston set features a 12.6:1 compression ratio. This is achieved with a 44.5cc dish volume in the piston.

Are these pistons suitable for a turbocharged engine?

These pistons are designed for naturally aspirated 3.6L Porsche 964 engines. While forged pistons are stronger, the specific compression ratio and design are optimized for NA applications. For forced induction, different piston specifications may be required.

What does 'Not CARB approved' mean for shipping?

This means the pistons do not meet California Air Resources Board (CARB) emissions standards. Consequently, they cannot be legally shipped to California for use on vehicles registered in that state.

Product Details

Mahle is a well-known name in engine components, especially for their high-performance pistons. This Mahle MS Piston Set is built for the Porsche 964 with a 3.6L naturally aspirated engine, designed to handle the demands of a performance rebuild. These aren't your everyday pistons; they're forged from strong materials to withstand higher cylinder pressures and temperatures that come with performance tuning.

This set features a 102mm bore and a 76.4mm stroke, with a 127mm connecting rod length and a 23mm wrist pin. The dish volume is 44.5cc, resulting in a 12.6:1 compression ratio. This higher compression ratio can lead to improved throttle response and more power when paired with the right engine management and fuel system. The forged construction means these pistons are significantly stronger and more durable than cast pistons, making them a solid choice for engines that see regular track use or aggressive driving.

This set includes six pistons, enough for a full engine rebuild. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
