Manley Nissan RB26DETT 86.5mm Bore 73.7mm Stroke +20cc Dome 9.0:1 Comp Piston Set - Set of 6

This set includes six forged pistons, designed for the Nissan RB26DETT engine. Each piston features an 86.5mm bore, a 73.7mm stroke, a +20cc dome volume, and a 9.0:1 compression ratio. These pistons are built using Manley's signature "Platinum Series" construction, which starts with domestic 2618 alloy forgings known for their strength and performance capabilities. They also come with premium chrome moly wrist pins, and the skirt profiles are carefully shaped to generate power while minimizing wear on the cylinder walls.

Manley pays close attention to the details that matter for engine building. The ring lands and grooves are machined to exacting standards, which helps ensure a better seal from the piston rings, leading to more efficient power delivery. Their unique fixturing process allows them to machine the skirt and the ring grooves in the same operation. This ensures the ring grooves are perfectly square to the piston skirt, a critical detail for proper ring function and engine longevity. This level of precision is why professional engine builders and tuners often choose Manley pistons for their builds.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're rebuilding your RB26DETT, these pistons offer a well-built foundation for a high-performance engine.
