Citroen / Peugeot 1.6L TU5JP4 80.0mm 8.7:1 (89.0mm Crank.) ZRP Forged Pistons Supersport Series


As the name suggests, these will be developed for mild to high tuning mainly for road or race cars that want to develop their engine for high mileage and/or street use. These will be designed by ZRP engineers and manufactured in Germany from 4032 (T6) high-silicon alloy, low-expansion alloy which allows the engine builder to run a closer piston to bore tolerance thus producing a better seal. This helps remove the slapping noise during cold start, common place among engines running forged pistons due to larger then OE bore clearances. We have chosen Round Style Skirt design for Turbo Application and X-Style skirt for Natural aspirated engines with Over size and deeper valve pockets to allow even the most extreme camshaft profiles to be used. They have Offset pins for quiet operation and the wrist pins are made from 9310 alloy. Other features include Anti-detonation grooves to protect the first rings, gas pressure accumulator groove for better ring seal and vibration relieve. Premium Japanese quality 1.00mm x 1.20mm x 2.80mm ring package included.

 

Optional coatings available per request:

Thermal barrier coating “Blast Off Bronze” / Moly Side-Skirt and Under-Crown coating “Stealth Black”
