MAHLE Motorsport Introduces Two New Porsche 911 2.7L – 2.9L Piston Kits Designed for Nickies™ Performance Air-cooled Cylinders

If you’ve got yourself a Porsche with a 2.7-2.9L engine that needs to be refreshed or expanded for more performance, MAHLE Motorsport has you covered with two new piston kits that are designed to pair perfectly with Nickies air cooled cylinders. The two different bores are a 90mm stock bore program and the second is a 93mm “big bore” kit which is where the 2.9L displacement comes from.

The good stuff here is the fact that you are getting MAHLE quality, materials, technology, and experience in every piston. You are also getting improvements like deeper valve reliefs to accommodate larger camshafts in both bore sizes and in the 2.9L variety the reliefs are expanded to allow for larger valves as well. Whether you are running on the street, SCCA or PSCA legal racing series, you can trust these pistons to get the job done.

Forged and ready to install, these are the new pistons to have in the world of the 2.7L Porsche engine.

Tighter clearances, reduced wear on piston and bore and quieter operation

Fletcher, NC, (August 18, 2020) – MAHLE Motorsport now offers two additional Porsche 911 2.7L based piston kits that pair perfectly with Nickies™ air cooled cylinders. One is a standard bore 90mm that retains the stock 2.7L displacement, and the second is a 93mm big bore piston + cylinder kit that equals 2.9L of displacement.  Both piston + cylinder kits incorporate deeper valve reliefs to accommodate performance camshafts, while the big-bore 2.9L piston also has larger valve reliefs to accommodate bigger valves. Each combination is designed for unmatched durability for street or for SCCA and PCA legal race applications.

Forged from 2618 alloy in a slipper skirt style forging to reduce weight and friction, the pistons feature a true 10.3:1 compression ratio at 1mm deck clearance (9.8:1 with a 1.4mm clearance) and are dual-coated with phosphate and MAHLE’s proprietary GRAFAL® coating for reduced drag and wear. The pistons also feature hard anodized top ring grooves for maximum durability to protect against micro-welding. The kit is complete with a steel 1.2mm top ring, 1.5mm 2nd and 3.0mm oil ring set, precision CNC machined bores, and heavy duty tool steel wrist pins.

MAHLE Motorsport, with its longstanding OE and race relationship with Porsche, has developed piston kits with a modern design and components that add up to increased power and durability. The modern ring sets are made from more durable materials and are dimensionally narrower and shorter to be more conformable, providing more consistent contact with the cylinders. The result is increased sealing and oil control.
