Bring it on! I love that engine. Not quite as powerful as the M engine, but also not as much of a gas hog and lighter (I think - though I'd love to get any actual weight values from anyone who knows).

The N54 (turbo) engine weighs 419 lbs complete, compared to 357 lbs for the N52 engine, which in turn is 22 lbs lighter than the M52 engine it replaced. So despite its lightweight intentions, it's still heavier than the old 3 Series six by about 40lbs.
Remember that 300 hp/300 lb-ft is stock. I'm sure it will only be a simple matter of a chip to take that to 330-350 horsepower. BMW showed a Z4 Racer with a 400 hp/400 lb-ft version at Geneva earlier this year.
