ZRP RODS – PISTONS SET OPEL 2.0L 16V C20XE STROKER 2.1L

The Opel 2.0L 16v C20XE 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 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 lightweight X-Style skirt design with a lower reinforcing band, with oversized and deeper valve pockets to allow the use of high-lift camshaft profiles. They have 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 compatible with the 91.00 mm stroker crankshaft C-OPE-002L.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 edgeLightweight X-Style skirt with lower reinforcing band for high-rpm applicationsValve pockets designed to accommodate oversized valves and high-lift camshaftsPistons designed to optimize squish for longer engine life and increased power potential.Optional coatings available upon request.”Blast Off Bronze” Thermal Barrier Coating.”Stealth Black” Moly Side-Skirt and Under-Crown Coating.Additional Information.Application. 2.0L 16v C20, 2.0L 16v C20XE.Bore Size. 86.50mm, 87.00mm.Weight. 301.305g.Stroke. 91.00mm.Compensation Ratio. 12.4:1OEM Compensation Ratio 10.5:1Compensation Height 27.75mmRod 143.00mmPin Diameter 21.00mmDeck Clearance -0.05CCS Dome +1.95CC, +2.3CCRing Set 21-GNH8650, 21-GNH8700Wrist Pin Pn WP051
