ZRP RODS – PISTON SET LANCIA 2.0L 16V INTEGRALE

The Lancia Delta Integrale 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 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 have 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 sealing 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 bore designed to allow oil to penetrate between the pin and the pin bore 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 applicationsValve pockets designed to accommodate oversized valves and high-lift camshaftsPistons designed to optimize squish for longer engine life and increased power potentialOptional coatings offered upon request”Blast Off Bronze” Thermal Barrier Coating”Stealth Black” Moly Side-Skirt and Under-Crown CoatingAdditional InformationApplication 2.0L 16v, 2.0L 16v Delta Integrale, 2.0L 16v CoupéBore Sizes 84.00mm, 84.50mm, 85.00mmWeight Gr 377, 386, 388Stroke 90.00mmOffset Ratio 8.5:1OEM Offset Ratio 8.0:1Oil Pressure Height 38.90mmAction 145.00 mmPin diameter 22.00 mmClearing the bridge -0.10CCS Dome -13.30cc, -14.10cc, -14.85ccSet of rings 21-GNH8400, 21-GNH8450, 21-GNH8500Wrist Pin Pn WP122
