Alright you see the outlet on the compressor side (that leads into the charge piping system), im trying to figure out the diameter of that, id measure it but im off at college during the week and im trying to order parts to have em there for the install this weekend. The turbo is a gt28r by garrett/avo. If anyone has a similar turbo theyve had experience with (aka t25), please help me and lemme know either what size approx. that is and if u used a reducer or what? Cause Im running 2.5" charge piping and I know that that diamter isnt 2.5" so ill probably use a reducer, if I can find out what size that is... :-\
