Hey guys, I just picked up a 2011 328xi 6MT sedan.
Last 7 of vin is A811245
I've discovered it has the N51 engine with the SULEV spec.
What's my best upgrade path here?
I was originally going to go with the 3 stage intake and euro airbox, but now I'm not sure what my best direction is. Most of the info here is old or vague on N51's.
Trading it in for a 335i isn't an option right now. My payments would be sky high because I'd be upside down. I really just want about 260hp out of her and I think that'll make me happy for a few years until I'm in a position to trade her in for an F30 335i
