This Mazda RX-4 is very unique. Sitting in the engine bay is a six-rotor built by rotary specialist Pule Performance in New Zealand. The 4.0 L motor produces 813 horsepower and 560 lb-ft of torque. It features RX-8 rotors, custom PPRE intake and exhaust manifold, 12 injectors, and six throttle bodies. Power is sent to the wheels through a TK600 five-speed manual transmission and 9-inch rear end with 35-spline axles.
