Manley Nissan RB26DETT +1.0mm OS 73.7mm Stk 87.00mm Bore 9.0CR +20cc Ext. Duty Piston Set w/Rings

If you're building a high-performance Nissan RB26DETT engine, a solid set of pistons is crucial. This is a set of forged pistons from Manley Performance, designed to handle the demands of serious engine builds. They are 1.0mm oversized, with a 73.7mm stroke, and a 87.00mm bore, featuring a 9.0:1 compression ratio and a +20cc dish for extended duty applications. These pistons are built to be a strong foundation for your RB26DETT.

Manley uses their signature 2618 alloy forgings for these pistons, which are known for being strong and reliable under high stress. They come with tool steel wrist pins and have moly skirt coatings to help reduce friction and wear against the cylinder walls. The ring lands and grooves are machined to very precise standards, which helps ensure a good seal for better power output. Manley also uses specific cam and barrel profiles on the skirts, which helps the piston generate power efficiently while also being gentler on the cylinder walls during operation. The way they machine these parts, using unique fixturing, means the ring grooves are perfectly square to the skirt, which is important for consistent performance.

This set includes the pistons, rings, and wrist pins, so you have the core components ready for installation. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For professional engine builders and tuners looking for reliable components, Manley pistons are a popular choice.
