David Mazzei built his 1993 Mazda RX-7 at his company Mazzei Formula in Birmingham, Alabama. The car is powered by a turbocharged and peripheral ported 2.6 L 26B four-rotor that makes 1080 horsepower and 630 lb-ft of torque to the wheels on 13-14 psi of boost. The engine features a Garrett GTX5533 98 mm turbocharger, custom water-to-air intercooler intake, Weldon mechanical fuel pump, and Haltech Elite 2500 ECU. The drivetrain uses a Quaife QBE69G six-speed sequential gearbox with a Spec triple-plate clutch and Carbonetic 1.5 Way limited-slip differential.
