I give up on this turbo...I can't get the center housing to rotate. I've pb blastered the shit, I've heated it up, I've wacked the hell out of it. I'm buying another turbo. Anyone want/need a t3 42/48, intake side rebuilt. VERY VERY VERY little shaft play, spins freely. It started spooling RIGHT off idle on my LS, made full boost before 4k (yea that whole 5-6 lbs).
