About this part

Product Details

If you're building a high-performance Nissan GT-R engine, these forged pistons from Manley Performance are a solid choice. Designed for the 3.8L VR38DETT engine, this single piston features a 95.5mm bore and a 94.4mm stroke, with a 1.5cc dish volume. Manley uses domestic 2618 alloy forgings, which are known for their strength and ability to handle the stresses of a performance engine.

These pistons are built with proven cam and barrel skirt profiles that help generate power while also being gentle on your cylinder walls. The ring lands and grooves are machined to exacting standards to ensure a good seal, which means more power and better efficiency. Manley's unique machining process ensures the ring grooves are perfectly square to the piston skirt, contributing to overall engine health and performance.

This piston comes with premium chrome moly wrist pins, and Manley offers upgrades to even more durable alloys if your build demands it. Keep in mind that this part is not CARB approved and cannot be shipped to California. It's a well-built component for serious engine builds.
