About this part

Product Details

This is a single forged piston from Manley Performance, designed for Nissan GT-R models with the 3.8L VR38DETT engine. It's built for stroker applications, featuring a 95.5mm bore and a -1.5cc dish volume. This piston is constructed from domestic 2618 alloy forgings, known for their strength and ability to handle demanding engine conditions.

Manley uses proven cam and barrel skirt profiles that help generate power while being considerate of cylinder wall wear. The ring lands and grooves are machined to strict standards, which is crucial for ensuring a good seal from the piston rings and maximizing engine output. This piston also comes with premium chrome moly wrist pins, adding to its durability. The unique manufacturing process ensures the ring grooves are square to the piston skirt, a detail that matters for consistent performance.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. It's a solid option for builders looking for well-built internal engine components for a performance build.
