It's pretty obvious the gray car in that video does not have the turbo engine in there.
And the turbo car's hood looks like crap. And the trunk is not far behind. And what's up wth those 'M3 V8 R biturbo' stickers? Couldn't even make a freaking badge? Geez. And website stickers look ridiculous too. Why do most people modifying the engine on M3s have to make the car look like a freaking Pontiac?
