I just cant say the N54 is better than the N20 because it has more power, there are other factors that can not be ignored.
Honestly I believe the F30 328i guys are getting quite silly trying to compare the N54 or N55 with the N20. No comparison people. NONE. I would even say that the N54 is more powerful than the N55, we are talking true power here at the wheels, while the N55 is a bit better in torque delivery lower on the rpm scale. But the N20? its not as smooth, its not as linear in its torque delivery, its not as nice sounding, its not as powerful (I know that is obvious) so what are we trying to compare here?

And I still stress as nice as the N20 is, its a highly stressed engine with over 18 lbs of boost. Would that matter to guys like me (and to 90% of the people that buy new)? no I am not planning to keep my cars for more than 36k to 40k miles since I am leasing.. But to someone that is going to keep their car and put 120,000 miles on it what engine to you think he/she would want to have? the one thats boosted at 18.5 psi or the one that is 9 psi?

So yes BMW did a remarkable job with the N20 I wouldn't be surprised if it becomes a classic, but it can't compare with the N54/55 6s.
