Keep in mind that dyno numbers are subjective and can vary wildly. Find a nice, optimistic dyno and 400whp may be possible but that doesn't mean it's any faster than a dyno reading 380whp.

Hey 380whp is perfect. My n54 xi wasn't putting that much down!

Yeah if i end up wanting more power then i'll look into turbo upgrades

I haven't heard many people complaining about reliability with the N55 so thats a good thing

It'll be stock for a while so I'll have to get used to stock power

There seems to be a ~20-25 hp difference at the wheels which has been chalked off to the larger 4" outlet on the F30's turbo, but someone correct me if I'm wrong.

I don't mean to get off topic though. OP, the N55 is definitely a great platform! Plenty of power, and hopefully there will be some more aftermarket turbo options soon for those of us hungry for more .

From what i've read it doesn't sound bad at all! As you said, aftermarket turbos are always a solution.

I haven't read up on the new F30s turbos but I just figured they could be tuned as the e9x series' turbos were

Good to hear. Now it's just a matter of finding the right e93!!

FBO N55 here, zero issues aside from a broken cup holder

haha I wanna join the e93 club before the summer! Don't sell it, you'll miss it too much

You know what, you're right. Trouble is, that extra weight gets to you every now and again...everything is a trade off

Thats true.. but a convertible in the summer is a very very good tradeoff!

Oh I know brother, it's just those other six months of the Jersey seasons that get to you I guess...

Loving it on a day like this though!

Awesome thread, I am going through the same dilemma right now. I was really against the N55 at first but this thread really opened my eyes and now I'm really considering it if the right car comes by. You can't really go against liability.

I had my Vanos crap out on me and had to replace a fuel pump as well (replaced under warranty). Otherwise it's been a great motor.

My N55 is more reliable than my N52.
