here's a video of a supra with BPU (basic performance upgrades) on the autobahn. Even the engine bay looks like its still got stock turbos.
Very impressed with how it reaches 300kmh very easily. Just imagine a Supra with APU (advanced performance upgrades) eg. with To4z turbo making almost 700ps ;)
(actually, that RS4 also nice, wagon summore, i got family :) but cannot afford laa in Msia).
