Dennis Köhler is a professional drifter in Germany who competes in this first generation (NA) Mazda MX-5. The roadster used to be powered by a turbocharged 1.8 L inline-four but Dennis switched recently to a 4.0 L Toyota 1UZ-FE VVTi V8 taken from a Lexus LS400. The engine runs off a ECUMaster EMU system and is connected to a BMW manual transmission via ABC Clutch adapter. The rear end is a BMW 740i with adapters to hold Mazda RX-7 turbo half-shaft. Steering is handled by an Opel Corsa C power steering rack. Along with changing the powertrain Dennis also changed the car’s appearance. He went with a black and gold livery inspired by the John Player Special F1 Lotus.
