I have a friend who has a brand new M90 ? ( one with the big pulley ). I have the older style, M62 ? (with the smaller pulley). He has all the fuel rails and the sensors for this setup. Can I swap them ? Can I use my old fuel rails and injectors ? I want to swap because I assume the later blower is more efficient ( right ? ) due t the larger pulley and it'* new. Oh yes , my buddy'* blower is for a 1998 GM ( brand unknown ). I own a 1992 Bonneville SSEi. Thanks for the help !
