ZRP RODS – NISSAN RB26DETT PISTONS SET

Nissan RB26DETT pistons are designed for moderate to high-performance tuning, primarily for road racing or club racing cars looking to develop their engines for high mileage and/or street use. Designed by ZRP engineers and manufactured in Germany from high-silicon, low-expansion 4032 (T6) alloy. This allows the engine builder to use a tighter piston-bore clearance, resulting in better sealing. This minimizes the slapping noise during cold starts, common among engines using forged pistons, ensuring quiet operation and low oil consumption.
We chose a full-round skirt design with a lower reinforcing band, with oversized and deeper valve pockets to allow the use of high-lift camshaft profiles. They feature offset pins for quiet operation, and the wrist pins are made of 9310 alloy. Other features include anti-knock grooves to protect the first rings, and a gas pressure accumulator groove for improved ring retention and vibration reduction. A pack of premium Japanese-quality 1.00 mm x 1.20 mm x 2.80 mm rings is included.Product Features and DesignAnti-knock grooves for long life and high performanceGas pressure accumulator groove in the second ring for increased wear resistance.Horizontal slots in the pin hole designed to allow oil to penetrate between the pin and the pin hole area.Precision CNC machined ring groovesHigh-silicon/low-expansion 4032-T6 alloyHoned pin holesClip-on cutouts on the intake side edgeFull-round skirt with lower reinforcement band for high HP/boost applicationsSide gas ports for improved ring sealingValve pockets designed for Allow for oversized valves and high-lift camshafts.Pistons designed to optimize squish for longer engine life and increased power potential.Optional coatings offered upon request.”Blast Off Bronze” thermal barrier coating.”Stealth Black” side-skirt and under-crown moly coating.Additional Information.Application.2.6L RB26, RB26DETT R32-R34.Bore Size.86.50MM, 87.00MM.Stroke.Offset Ratio. 8.8:1/8.9:1OEM Compensation Ratio 8.5:1Compensation Height 30.00mmRod 121.50mmPin Diameter 21.00mmDeck Clearance -0.15CCS Dome -15.50CCRing Set 21-GNH8650, 21-GNH8700Wrist Pin Pn WP092
