So as the title says Im rebuilding the turbos. I would love to go Ko4 but since Im still in highschool money is a little tight. But as it goes to rebuilding, when i try pulling the compressor housing off the bitch wont come off. I have all the bolts out and the housing spins arround freeling but wont pull off. Is there any secret way to pulling off? Also if I were to want to hybrid these little guys how abouts would I go with it?
