Mahle MS Piston/Cyl Set 76-83 Por 911 3.0-3.2L 98mm Bore 70.4mm Stk 127.8mm Rod 22mm Pin 40cc 10.2CR

This is a Mahle MS Piston and Cylinder Set specifically for 1976-1983 Porsche 911 models with 3.0-3.2L engines. If you're rebuilding the top end of your air-cooled 911, this set gives you the core components to restore or enhance your engine's performance. Mahle is a well-known name in engine components, and this set is built to meet the demands of a performance rebuild.

This set features a 98mm bore, which is the stock size for these engines, ensuring a direct fitment. It's designed to work with a stock 70.4mm crankshaft and a 127.8mm connecting rod, utilizing a 22mm wrist pin. The pistons have a 40cc combustion chamber volume, resulting in a 10.2:1 compression ratio. This updated compression ratio can offer improved power and throttle response over stock, especially when paired with appropriate engine tuning. The cylinders are precision-machined to match the pistons, ensuring proper sealing and heat dissipation, which is critical for the longevity of an air-cooled engine.

When undertaking an engine rebuild of this caliber, it's important to ensure all components are clean and properly lubricated before installation. This set includes the pistons and cylinders; other necessary components like rings, wrist pin clips, and gaskets will need to be sourced separately. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for detailed guidance.
