People dont bother with the m52b25 since its 150bhp, but combine it with an m50 inlet and a remap surely it should give good power gains???
according to this site

If the above statment is correct then surely you can get an m52b25 to produce more power than a standard m50b25??The swap combined with a decent remap and installation of a cold air intake and less restricted exhaust should bring your 328i to the region of 230BHP and 323i to over 200BHP(depending on the condition of your engine).
Just wonderd what veiws people have on this?? as the engines may be easier to get hold of and cheaper ?
it would also be lighter
