About this part

Product Details

Built from domestic 2618 alloy forgings, these Manley Extreme Duty pistons are designed for the demanding needs of the Nissan GT-R's 3.8L VR38DETT engine. With a 99mm bore and a 9.8:1 compression ratio, they offer a -2cc dish volume, making them a solid choice for serious engine builds where strength and reliability are paramount. Professional engine builders and tuners often turn to Manley for their reputation in superior performance and durability.

Manley's signature cam and barrel skirt profiles are engineered to generate substantial power while minimizing wear on your cylinder walls. They also employ unique fixturing that allows for skirt turning and ring groove machining in a single operation. This process ensures ultimate squareness between the ring grooves and the skirt, which is critical for proper ring seal and overall engine efficiency. The exacting standards applied to the ring lands and grooves further enhance this seal, translating directly into more power and better performance from your engine.

Included with this set are premium chrome moly wrist pins, known for their strength. For those seeking even greater durability, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys on select part numbers, though this specific set comes standard with chrome moly. This piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
