Being new to turbo'd BMW's I always wondered as to why I haven't seen more BIG builds. The N55 is an inline 6 correct? When comparing it to my brothers Mk IV Supra's engine design, wouldn't the same logic apply? Slap a larger turbo on, add a front mount, and adjust timing/fuel, hell even reinforce with better rods, etc. Is this just not possible with our cars (strength of block, clearance issues, lack of after market support)or has it just not been figured out yet? I'm hoping that tuners or anyone with experience can step in and shed some light on this?
