About this part

Product Details

Forged from domestic 2618 alloy, these Manley pistons are built for serious performance in your Nissan RB26DETT engine. The +17cc dome volume combined with an 86.25mm bore and a 9.0 compression ratio are key specifications for tuning your engine's power output. Professional engine builders and tuners choose Manley for their reliability and the performance gains these pistons can help achieve.

Manley's signature design includes proven cam and barrel skirt profiles, which help generate substantial power while also being gentle on your cylinder walls. This attention to detail extends to the exacting standards for piston ring lands and grooves, ensuring an enhanced ring seal for more efficient combustion and increased power. The unique fixturing Manley uses allows for skirt turning and ring groove machining in a single operation, which guarantees ultimate squareness between the ring groove and the skirt, a critical detail for engine longevity and performance.

This set includes premium chrome moly wrist pins, known for their durability. For those pushing the limits, Manley offers upgrades to even tougher alloys. You'll also find that the ring lands and grooves are machined to strict standards, which is crucial for proper ring seal and overall engine health. This piston set is a well-built foundation for a high-performance RB26DETT build, but please note it is not CARB approved and cannot be shipped to California.
