Half the 135i's on this forum can't even hook up tires since they make 400 ft/lbs at 2k rpms.
haha they only make 400ft-lb after more like 4krpm, boost only starts around 2k.

i'm personally swapping in an N54. cheaper than any other option lol

you know the N52 is actually REALLY torquey for a 3.0 NA right? it's rated at near 320ft-lb stock... mine pulls pretty hard from near idle..

I have yet to dyno DISA & no tune. So not sure how much DISA added , but i know the gains are there
pretty much bang on (for a dyno dynamics)

i got (with my car BADLY needing a service) 204whp on a DD with my 130i.. i'd expect it to be around 220-225whp in healthy tune (again, on the same DD).. 190whp on a DD for a 128i would be pretty spot on in that case (235 crank?)

230-240 is way too high an estimate, at only 270 odd crank... all depends on the dyno though really.
