Manley Nissan GTR VR38DETT 99mm Bore 88.4mm Stroke -2cc Dish Turbo Tuff Piston Set w/ Rings

If you're building a high-performance Nissan GT-R with the VR38DETT engine, this Turbo Tuff piston set from Manley Performance is a solid choice. These pistons are designed for a 99mm bore and feature an 88.4mm stroke with a -2cc dish, making them suitable for serious engine builds where increased power and durability are key. Manley has a strong reputation among professional engine builders for producing reliable components that can handle demanding conditions.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to perform under high stress. The pistons feature proven cam and barrel skirt profiles, designed to help generate substantial power while also being considerate of your cylinder walls during operation. They also pay close attention to the ring lands and grooves, holding them to strict standards to ensure a better seal from your piston rings, which translates directly to more power. The included wrist pins are made from premium Chrome Moly, adding to the overall durability of the assembly.

This set includes everything you need to get started with the pistons themselves, along with the necessary rings. Manley's manufacturing process uses unique fixturing that allows them to machine the skirt and ring grooves in a single operation. This ensures that the ring grooves are perfectly square to the piston skirt, which is critical for optimal ring seal and engine performance. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
