MAHLE Motorsport has introduced its PowerPak Piston Kit for Porsche 964/993 enthusiasts seeking maximum displacement from their engines. It features high-quality OEM MAHLE Nikasil-coated cylinders available in slip-in or machine-in, specifically designed for engines with an 80.4mm stroke and 127mm rod length taking the original OEM 3.6L to a remarkable 3.9L.
Backed by over 100 years of performance experience and using MAHLE-manufactured machinery that engineers the piston kit to exacting tolerances, these pistons are forged from 4032 alloy and deliver a 11.4:1 compression ratio with 1mm deck clearance (10.9 with 1.4mm clearance). The PowerPak kit comes complete with nitrided steel 1.2mm top ring, 1.2mm Napier 2nd ring, and 3mm oil ring set, precision CNC machined pin bores, and a heavy-duty wrist pin and locks.
The pistons are dual-coated with phosphate and MAHLE’s GRAFAL skirt coating and feature slipper-style skirts for maximum strength. For more product details, view MAHLE Motorsport’s Porsche Application Guide here.
