ZRP RODS – PISTONS SET OPEL 2.0L 16V C20XE AND Z20LET

The Opel 2.0L 16v pistons are designed for moderate to high-performance tuning, primarily for road racing or club cars looking to develop their engines for high mileage and/or street use. Designed by ZRP engineers and manufactured in Germany from a high-silicon, low-expansion 4032 (T6) alloy. This allows the engine builder to use a closer 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-detonation grooves to protect the first rings, a gas pressure accumulator groove for improved ring sealing and vibration reduction. A premium Japanese-quality 1.00 mm x 1.20 mm x 2.80 mm ring pack is included.*Note: This piston kit is designed to fit all Opel 2.0L 16v Z20 and C20 engines with 21.0 mm piston pins.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 alloySide gas ports for improved ring sealingHoned pin holesClip-on cutouts on the intake side edgeFull-round skirt with lower reinforcement band for high HP/boost applicationsValve 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.2.0L 16v C20XE and Z20LET, 2.0L C20 / 2.0L Z20Bore Sizes.86.00mm, 86.50mm, 87.00mmWeight.321g, 326g 333Stroke 86.00mmOffset Ratio 8.8:1OEM Offset Ratio 8.8:1OEM Offset Height 30.25mmRod 143.00mmPin Diameter 21.00mmDeck Clearance -0.05CCS Dome -14.50cc, -15.25cc, -16.00ccRing Set 21-GNH8600, 21-GNH8650, 21-GNH8700Wrist Pin Pn WP092
