Just trying to inform people like yourself that continue to spread misinformation about the N55 because they didn't know about the motor changes in the later years and continue to say the N55 doesn't make power like the N54 and can't sustain power any better either because none of that is true.
It didn't take them 9 years to make a "better" motor to succeed the N54 either. In 2014, the N55 surpassed the stock whp/wtq of the N54. 1M and M2 N55 make similar peak power numbers, but the N55 breathes longer thus the reason why it's the quicker and faster car.
You probably don't know that the 2014+ N55 also uses the S55 forged rods and rod bearings or that the crank in the M235/M2 N55 is forged (vs cast in all other N55s) along with additional oil coolers so that oil overheating is never an issue in those two cars. By better, you're surely not talking about reliability between the N54 and N55  |
Oh lord, the N54 was perfectly reliable once they finally got around to sorting out the HPFP. But it did take $20k of warranty repairs on ours to get it all sorted, and tons of out of service days. One reason I know how much better a stock E9x handled.
