While searching Facebook for new projects, we found a listing for a Honda Integra DB8 sedan with a turbocharged Nissan RB25 inline-six. The engine has been upgraded with RB26 internals, Audi R8 coilpacks, Greddy intake, and Nismo 555 injectors. Running on a PowerFC ECU and a Holset HX35 at 23.2 psi (1.6 bar) the engine produces around 550 horsepower. The Skyline manual transmission uses a Nismo twin-plate clutch. The Skyline AWD system was swapped over using custom subframes and custom suspension. This means the driver can switch on the fly between RWD and AWD which you can see in the video posted below.
