Mahle MS Piston/Cylinder Set 64-68 Por 911 2.0L 80mm Bore 66mm Strk 130mm Rod 22mm Pin 38.8cc 10.0CR

Forged from high-strength aluminum alloy, this Mahle piston and cylinder set is built for the demanding rebuilds of 1964-1968 Porsche 911 models with the 2.0L engine. The 80mm bore and 66mm stroke are precisely matched to achieve the specified 10.0:1 compression ratio, utilizing a 38.8cc combustion chamber volume. This set is designed for enthusiasts looking to restore or enhance their classic air-cooled Porsche engine with well-built components.

Mahle's expertise in piston manufacturing is evident in the robust construction of these forged units. Forging creates a denser, stronger grain structure compared to cast pistons, making them more resistant to the high pressures and temperatures found in performance engines. The included cylinders are precision-machined to perfectly complement the pistons, ensuring a tight seal and optimal performance. The 130mm connecting rod length and 22mm wrist pin diameter are critical dimensions for proper engine assembly and function, ensuring this set integrates correctly with your existing or rebuilt engine components.

This set is a significant upgrade for anyone undertaking a serious engine overhaul. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and consult with a qualified mechanic to ensure proper fitment and assembly for your specific application.
