Check Sig for current mods to my 97 Regal GS. I am considering going intercooled in the near future, Of course I would get a full size, and presumably it would be to my benefit to drop pulley size again. I am thinking I will be able to get away with a 3.25 (also convenient because I have one laying around...), Question is, will I need to upgrade any part of my fuel system when I go intercooled, get a smaller pulley, and get my tune adjusted? I know the nooby thread says bigger injectors when any smaller then 3.1, but I dont think I will be able to go that small, or will I? What do you think I should anticipate? rewire kit? fuel pump upgrade? bigger injectors?
