This Mazda RX-8 was built by KMS Engine Performance in Henryków-Urocze, Poland. KMS replaced the damaged factory rotary with a 4.3 L Toyota 3UZ-FE V8. On top of the V8 sits a set of individual throttle bodies and is all controlled by a ECUMaster EMU controller. The engine produces 302 horsepower and 303 lb-ft of torque to the rear wheels. Behind the engine sits a six-speed transmission out of a Nissan 350Z and a BMW LSD rear end. An Android tablet running VEMS data display software replaced the factory gauges.
