The sporting soul of SIMCA is reborn thanks to our exclusive collection of high-performance forged engine parts. From WISECO pistons forged with optimised grain and MANLEY connecting rods capable of withstanding 8000rpm, to the SUPERTECH sodium-filled valves that propelled the 1000 Rallye to victory, every component tells a story of performance. COMETIC multi-layer head gaskets withstand the 180hp of a tuned Rush, while ARP head studs keep everything intact under 12 bar of pressure. Complete the build with our rally-raid-proven ACL RACE Series bearings, PAC RACING dual valve springs calibrated for racing camshafts, and dynamically balanced crankshafts for your most demanding restorations.
Revolutionary 3-click navigation: instantly identify the exact parts for your Poissy, Rush or derivative block. Preparers of the historic Tour de Corse trust our kits to turn a docile 1301 into a race machine producing 165hp. From 1200S Coupés restored to Gordini specification to 1000 Rallye 2 cars modernised for VHC endurance racing, our system guides your project with surgical precision. Every part carries on the French excellence that once made Alpine and BMW tremble on the special stages.
Dual stock in France and across Europe guarantees same-day dispatch on orders before 5pm, with express delivery in 72 hours. Enjoy the best prices in Europe, backed by 20 years of expertise in classic French engines. Certified competition quality, compatible with FFSA Group 1-2 homologation.
