ZRP RODS – VW 2.0L TFSI/TSI BELT & CHAIN ​​PISTON SET

The Audi/VW 2.0L TFSI 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, and 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: Pistons are designed for use in all engine configurations with a 21.00 mm pin.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 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 TFSI/TSI Engine with Belt and Chain Drive, 2.0L TFSI/TSIBore Sizes. 82.70mm, 82.50mm, 83.00mmWeight. 308.313gStroke. 92.80mmRpm Ratio.
