N54 or N55?

eurocharged · 02-08-2010, 02:12 PM

Isn't one difference between the n54 and n55 is that the n54 has 2 turbos as the n55 only has one, i guess that's one way he could check. He possibly have a n55, maybe BMW put one in there to test it, like a guinea pig type deal. to see if there's any errors with it before they start putting it in to production on these models so they don't have a problem like Toyota did and have to recall all the new models

That last post about putting an N55 in as a guinea pig kind of scared me. From the picture that I posted you guys are Positive that I have the N54? Thanks, and sorry for being a PITA!

FWIW - I emailed BMW regarding my car which is being built now (2010 E90). They replied this AM "Your car will have the N54."

and you're a vendor? no car company would do that, the engine doesnt even look the same

Thanks again, guys! I'm sorry about the confusion that I caused! I guess the engine does not feel as powerful because the 335i x drive is 400 pounds heavier than the 1er, and does not have the performance exhaust that I had on the 135i? Sound plausible? To anyone who Has to drive today in the East, please be careful!!

No worries. I would have been content with either engine option myself, but I certainly appreciate the ability to take advantage of all the aftermarket options already available for the N54.

Thanks for the information everybody.
