Description

Experience enhanced performance and durability with the Manley Performance Nissan SR20DE/DET 86.5mm +.5mm oversized bore dish piston set. Crafted from high-strength 2618 alloy forgings, these pistons are engineered for professional engine builders and tuners seeking reliable power upgrades. The precision-engineered cam and barrel (skirt) profiles optimize power output while minimizing stress on cylinder walls, ensuring long-lasting performance under demanding conditions.

The pistons feature moly skirt coatings on select part numbers to reduce friction and wear, extending engine life. Chrome Moly wrist pins come standard, providing exceptional strength and durability; for select SKUs, upgraded options such as 9310 and Turbo Tuff/DLC alloys are available to meet high-performance requirements. Strict manufacturing standards guarantee precise ring lands and grooves, resulting in superior ring seal, increased compression, and improved overall engine efficiency.

Unique fixturing technology allows for skirt turning and ring groove machining in a single operation, ensuring consistent ring to skirt squareness and optimal sealing. This design enhances power delivery and reliability, especially in high-stress applications. The piston set is suitable for use in performance-oriented builds, offering a reliable upgrade over stock components.
