What material are these Manley 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 well-suited for demanding 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 optimize the piston's movement within the cylinder. They help reduce friction and wear on the cylinder walls while still allowing the piston to generate substantial power.

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

This specific piston is designed for the 3.8L VR38DETT engine and features a 95.5mm bore, intended for stroker applications. It's crucial to verify that this bore size and piston dish volume match your engine's specific build requirements.

About this part

Product Details

If you're building or rebuilding the heart of your Nissan GT-R's 3.8L VR38DETT engine, these forged pistons from Manley Performance are a solid choice. They're designed to handle the demands of a performance engine, offering improved strength and reliability over stock components. This specific piston is a 95.5mm bore size, intended for stroker applications, and features a -1.5cc dish volume.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their superior strength and durability under high stress. The pistons also feature precise ring lands and grooves, which are critical for achieving a good seal with the piston rings, leading to better power output and efficiency. The cam and barrel skirt profiles are carefully shaped to reduce friction and wear on the cylinder walls while still generating substantial power. This attention to detail in machining ensures the piston moves smoothly and efficiently within the cylinder.

Each piston comes with a premium chrome moly wrist pin, and Manley's unique manufacturing process ensures the ring grooves are perfectly square to the piston skirt for optimal performance. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
