High-Compression 2618 Forged Pistons for Serious 2JZ Builds.
The Manley Platinum Series Forged Piston Set is engineered specifically for high-output Toyota 2JZ-GTE builds demanding exceptional strength and responsive power delivery. Forged from high-tensile 2618 aircraft alloy, these 86.5mm (+0.5mm overbore) flat top pistons yield an aggressive 10.0:1 compression ratio, making them ideal for modern turbocharged ethanol (E85) and race-gas combinations. Built using Manley's single-operation machining fixture to ensure absolute squareness between ring grooves and skirts, this set includes premium chrome moly wrist pins, round wire locks, and a matching ring pack.
