Amazing project car, just shows you how far you can go with a BMW M
There's just one thing that's on my mind and thats, how much did the mods cost? I think you could buy yourself a nice E60 M5 for the price of those mods.
And also remember that the M3 has 1100bhp (at the flywheel?) as long as it has cooling. Once the cooling is gone, the engine is gone and thus the bhp is gone. There was a lambo vid of that car on that site a while back. At the end of that vid the driver sais something in lines of "I don't have enough water left".
