Mazda RX-3 with a 26B Quad-rotor

Telly Pieratos’ amazing Mazda RX-3 has been around for 20+ years and it recently received a big upgrade under the hood. RP Customs were tasked with getting the car setup and turned to Curran Brothers Racing to build a peripheral ported 26B four-rotor engine for the RX-3. The engine is naturally aspirated, fuel injected and runs a dry sump oiling system. The car runs a Tremec transmission and Ford 9″ rear end. The best time I could find running the new engine was a 10.5 sec at 134 mph. Listen below as the four-rotors scream.
