Manley Nissan GT-R 3.8L VR38DETT 95.5mm Flat Top Grade 1 Extreme Duty Piston w/Ring

Manley Performance is well-known for making strong engine components for demanding builds. This piston is a prime example, designed specifically for the Nissan GT-R's 3.8L VR38DETT engine. It's a flat-top, 95.5mm bore piston built for extreme duty, meaning it's ready to handle serious power and the stress that comes with it.

What sets these pistons apart is the material: they use domestic 2618 alloy forgings. This alloy is chosen for its superior strength and performance characteristics, which is crucial when you're pushing an engine hard. Manley also pays close attention to the details, like the piston ring lands and grooves, holding them to strict standards. This helps ensure a better ring seal, which translates directly into more power. The cam and barrel skirt profiles are also carefully designed to generate power while being easier on your cylinder walls, a practical consideration for engine longevity.

For those building a high-performance GT-R, these pistons are a solid option. They come with chrome moly wrist pins for added durability, and Manley's unique manufacturing process ensures the ring grooves are perfectly square to the skirt. This level of precision is what professional engine builders rely on.
