What material are these pistons made from?

These Manley pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and performance characteristics, making it suitable for high-performance engine applications.

What is the purpose of the cam and barrel skirt profiles?

The cam and barrel profiles on the piston skirts are designed to manage the piston's movement within the cylinder. This helps to reduce noise and minimize wear on the cylinder walls, while still allowing the piston to perform effectively.

Are these pistons compatible with all Nissan GT-R models?

These pistons are specifically designed for the 3.8L VR38DETT engine found in the Nissan GT-R. However, they are not CARB approved and cannot be shipped to California due to emissions regulations.

About this part

Product Details

Starting with domestic 2618 alloy forgings, these Manley pistons are built for the demanding VR38DETT engine found in the Nissan GT-R. They're designed with a 95.5mm bore and 88.4mm stroke, aiming to provide the strength and reliability needed for serious engine builds.

Manley uses proven cam and barrel skirt profiles that help manage piston rock, reducing wear on your cylinder walls while still allowing the piston to generate substantial power. The ring lands and grooves are machined to strict standards, which is key for getting a good seal from your piston rings. This attention to detail means better compression and more power from your engine. They also come with chrome moly wrist pins for added durability.

These pistons are not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your GT-R's engine, these are a solid option from a well-known performance parts manufacturer.
