Manley Platinum Series Extreme Duty Forged Piston Set - Toyota 2JZ-GTE 86.5mm Bore 10.0:1 CR 9310 Pins (609105CE-6)
Extreme Duty 2618 Forged Pistons with Upgraded 9310 Alloy Wrist Pins for Maximum Boost 2JZ Builds.
The Manley Platinum Series Extreme Duty Forged Piston Set takes the proven performance of Manley's 2JZ flat top piston architecture to the highest level of motorsport durability. Engineered specifically for extreme cylinder pressures found in four-digit horsepower drag racing and high-boost ethanol (E85) setups, this "CE" Extreme Duty version upgrades the standard wrist pins to high-tensile 9310 alloy tool steel wrist pins. Paired with high-strength 2618 aircraft alloy forgings, moly-coated skirts, and Total Seal rings, this 86.5mm (+0.50mm overbore) set is built to eliminate wrist pin deflection and resist detonation under the most demanding conditions.
