Really impressed to see those figures from the b28, that's awesome:coolShake:
Ive missed my 330i so very much, the car was just amazing! You think the altitude has anything to do with it being so close to the b30, I'm surely it's loss should be equal on the b30 and b28?
My 330i felt so much better then my 323ci, love that engine it's just such a gem, but been toying with the idea of swapping in an m52b28tu to replace my b25tu, wondering if it was worth it, because it will be a much straight forward swap then the m54b30 swap, but if the b28 pulls the same as a b30 then il definitely go the b28,route!!!
Any inside info on the charateristic of then b28tu vs m43b30? You reckon for ease the b28 would be the better option?
Very curious to hear your insight :=):
