i like the idea of bmws running jap turbo engines...the 1jz(NA) sounds much more refined but still has that 6 cylinder sound...its much more value for money upgrade...and provided its done neatly, it way better than anything bmw for the same cost....don't see whats the big deal...engines are meant to produce power thats it...even the f1 cars are doing it like lotus renault....lotus has all this racing pedigree and yet they use renault engines....in f1 2009 what was effectively a honda ended up fitting a mercedes engine...so some people need to get over themselves and look at an engine for what it is...essentially a powerplant.
