ZRP Forged Pistons for Opel 2.0L 16v C20XE and Z20LET 86.00mm 8.8:1

The Opel 2.0L 16v pistons are developed for moderate to high-level tuning, primarily for street or club racing cars that want to develop their engine for high mileage and/or street use. Designed by ZRP engineers and manufactured in Germany using 4032 (T6) high-silicon, low-expansion alloy. This allows the engine builder to use tighter piston-to-cylinder clearances, which produces better sealing. This minimizes knocking noise during cold starts, common in engines using forged pistons, providing quiet operation and low oil consumption. We have chosen a full-round skirt design with a bottom reinforcement band, featuring oversized and deeper valve pockets to allow the use of high-lift camshaft profiles. They have offset pins for quiet operation, and the piston pins are made of 9310 alloy. Other features include anti-detonation grooves to protect the top rings, a gas pressure accumulator groove for better ring sealing, and vibration relief. Includes a premium Japanese-quality 1.00mm x 1.20mm x 2.80mm ring package. *Note: This piston kit is designed to fit all Opel 2.0L 16v Z20 and C20 engines with 21.0mm piston pins.
