wouldnt have a clue, narrow down to what power you want, say 250-300kw's, that will give you a range of turbos in that power range.
then you look for one that will fit your flange, T3 i think ?
then lag ? brand ? all that shit ... it got to much for me and will just end up getting defected for it anyway .
so i just gave up and im going the highflow way. legal
