I drove a 2007 N54 for three years. I know quite well how well that engine performs. I have driven both and owned both, so I have a direct means of comparison through experience. Do you?? I didn't think so.

Likewise.

From my reading on various other threads/forums, my understanding is the fuel system on the N55 is now supplied by Bosch (the one on the N54 was from Siemens). Also, the turbo is now supplied by Borg Warner (where the two on the N54 were, I believe, from Garrett).

I believe the short block is the only thing the two engines have in common. Perhaps someone with more insider knowledge can confirm or deny?

I've only had my N55 powered 335 for a couple months, and I came from a 328 before that so I can't make a direct comparison, but so far I'm certainly very happy with the performance. Time will tell on the reliability side.

N54 turbos are MHI, not Garrett.

Stock for stock, I think the n55 feels better than the n54. Just as responsive but with noticeably more power. Power delivery is also smoother which may be due to Valtronic. There is talk that the crankshaft isn't forged as it is in the n54. But it's not like crankshaft failures are common in the first place.

Our n55 is reponding well to tuning. Still too early to see if it matches the n54 in max tuned performance. Great engine though.

OMG!!

this from the mouth of one of the advanced piggyback tuners ---

Shiv, say it isnt so .. cuz the N54 has to be superior

(but i do agree with you, btw)

that being said, i still think the greatest potential in either platform has yet to be tapped --

WAWAWEEWA

..... This is great news coming from someone as respected and experienced with these cars as Shiv. I can't wait to get mine!

Sorry I couldn't help myself. I was watching Borat again last night

OneFastE92 · 06-15-2010, 06:44 PM

Can't wait to see those N55's fully modded. It actually does have the same fuel pump as the n54.

GL w/ that ! the shelves must be full of remanufactored HPFP.
they will never run out now. they have an endless supply driving all over America.

shockin330i · 10-19-2010, 01:43 AM

my n55 has 11k miles and sounds like a diesel. I'm assuming its the wastegate.

ciomas · 10-19-2010, 03:42 AM

Im about to hit 15k km on the n55 and the cold start rattle started a few days ago :/

It's true, but the N55 HPFP operates at a lower pressure. I don't think the lower pressure saves the HPFP, but it can stay broken for longer without anyone noticing it

IcebergM4 · 10-19-2010, 12:02 PM

Oh shit! I better go outside right now to start her up and listen. Dammit BMW!!

shockin330i · 10-19-2010, 01:55 PM

So is their a fix for this? What do I go to the stealership and say? "Hi my car sounds like a diesel, might be the waste gate..."

Shockin, I just spent the past 20 minutes listening to my car and it sounds like a diesel too. The rattle is VERY noticeable

Even if you went to the stealer and they heard it, they still probably would say it's normal. WTF BMW!!!!!!!!

IcebergM4 · 10-19-2010, 02:16 PM

I'm not even at 9000 miles yet!!

shockin330i · 10-19-2010, 02:29 PM

Yeah, I was made fun of the other day

"Why does your car sound like that? Sounds like somethings broken"

mycoupe · 10-20-2010, 12:09 AM

Why doesn't someone just make some god damned manifolds for aftermarket turbos and wastegates for these fucking cars already!?!?!?! They don't even have to be big turbos....just ones that will work a little better for a little longer

wankelrx · 10-20-2010, 09:45 AM

Mine has 400 miles on it now and has rattled when cold from day 1. It sounds like mine is coming from the rear of the car. I suspected the exhaust valve. Once warm I haven't heard it rattle.
