Top Secret Toyota Supra with a twin-turbo 1GZ-FE V12

Top Secret took home Best of Show honors from the 2007 Tokyo Auto Salon with their crazy Toyota Supra with a twin-turbo 5.0 L 1GZ-FE V12. You can tell from the video that the engine swap did not leave much room for the radiator which was placed in the back. Currently the boost has been turned down on the twin turbochargers for testing. Behind the engine sits a ORC clutch, JZA80 Getrag six-speed transmission, and Cusco 1.5 way LSD.
