What is included in this Mahle piston set?

This set includes six Mahle MS pistons. It is designed for specific Porsche 911 and 930 Turbo models from 1978-1992. The set details include a 100mm bore, 74.4mm stroke, 127mm rod length, 23mm pin size, 0.5cc dish volume, and a 7.0:1 compression ratio.

What is the advantage of forged pistons like these?

Forged pistons are made from a solid block of aluminum alloy that is heated and hammered into shape. This process creates a stronger and more durable piston compared to cast pistons, making them better suited for high-performance applications or engines that experience higher pressures and temperatures.

Are these pistons compatible with all 911 models from 1978-1992?

This specific Mahle MS piston set is designed for the 1978-1992 Porsche 911 and 930 Turbo models. It's important to verify the exact engine specifications and fitment for your particular vehicle to ensure compatibility, especially if your engine has been modified.

Product Details

This Mahle MS Piston Set includes six pistons, designed for 1978-1992 Porsche 911 and 930 Turbo models. These pistons are built to a 100mm bore size, with a 74.4mm stroke and a 127mm rod length. The 23mm pin size and 0.5cc dish volume contribute to a 7.0:1 compression ratio, making them a solid choice for rebuilding or upgrading your engine's top end.

Mahle is a well-known name in engine components, and this set reflects their commitment to well-built parts. The pistons are forged, which means they are created from a solid block of aluminum alloy that is heated and hammered into shape. This process results in a stronger, more durable piston compared to cast pistons, able to withstand the higher pressures and temperatures found in performance or heavily used engines. The specific dish volume and pin size are critical for achieving the correct compression ratio and ensuring proper piston-to-valve clearance, especially when working with modified cylinder heads or camshafts. This set is intended for 6-cylinder engines, matching the configuration of the Porsche 911 and 930 Turbo.

When undertaking an engine rebuild of this caliber, it's important to ensure all components are clean and properly lubricated before installation. Refer to the manufacturer's detailed installation instructions for specific guidance on assembly and break-in procedures. Please note that this part is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
