Mahle Motorsports 2.7L Porsche 911 Pistons Matched for Nickies Cylinders

Mahle Motorsports' new pistons for the Porsche 911 2.7-liter engine are engineered specifically to be paired with LN Engineering's Nickies billet aluminum air-cooled nickel silicon carbide plated cylinders. These pistons are available individually or packaged together with Nickies cylinders as a complete piston and cylinder kit. When paired with these cylinders, the kit increases the compression ratio of the stock 2.7L engine to 10.3:1, or 9.8:1 when using a 1.4mm deck clearance, with bores sizes and displacements up to 93mm and 2.9 liters.

Each piston is forged with a thick slipper skirt design to maximize strength while reducing weight. Larger valve pockets are machined into the crown, allowing compatibility with high-lift camshafts and oversized valves. For durability and performance, the pistons feature a dual coating that includes phosphate to prevent micro-welding and Mahle’s proprietary Grafal skirt coating to reduce friction and noise. The crown volume is 26.1cc, and each piston is equipped with a steel top ring measuring 1.2mm, a 1.5mm second ring, and a 3.0mm oil control ring set. Wrist pin bores are precision-machined, and each piston weighs 402 grams, paired with a 22mm heavy-duty steel wrist pin that weighs 101 grams.

This Mahle Motorsports and Nickies combination is designed to deliver superior piston-to-cylinder compatibility, allowing for tighter clearances, quiet operation, and reduced wear. Unlike other aftermarket kits that force compromises on materials, machining, or coatings, this pairing ensures optimal performance tailored for air-cooled Porsche engines. This collaborative effort brings back a much-needed option for 2.7L Porsche owners seeking OEM-level engineering with modern advancements in materials and coatings.
