Manley Nissan RB26DETT 86.25mm Bore 9.0 CR +20cc Dome Extreme Duty Piston Set w/ Rings

If you're building a serious Nissan RB26DETT engine, you need a piston set that can handle the stress. This Extreme Duty piston set from Manley Performance is built for just that. These aren't your average pistons; they're forged from 2618 alloy, a strong material chosen for its ability to withstand high cylinder pressures and temperatures common in performance applications. The 86.25mm bore size is a common upgrade for the RB26, and the 9.0 compression ratio with a +20cc dome is designed for boosted applications where you need a balance of power and detonation resistance.

Manley puts a lot of thought into how these pistons work inside the cylinder. They feature proven cam and barrel skirt profiles, which help the piston move smoothly without excessive wear on the cylinder walls. This design also contributes to generating substantial power. The ring lands and grooves are machined to very strict standards, which is crucial for getting a good seal from your piston rings. A good ring seal means more power and better control over combustion. For added durability, these pistons come with premium chrome moly wrist pins, and Manley's unique machining process ensures the ring grooves are perfectly square to the piston skirt.

This set includes the pistons, rings, and wrist pins, making it a comprehensive solution for your engine rebuild. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're aiming for maximum performance and reliability from your RB26, this Manley piston set is a solid choice.
