not sure, but i wouldnt suggest it, the guys at the shop would know better than me. how much power do you plan on running. its all about the power not the size of the turbo i believe that will mess up your engine. A big turbo running small power shouldnt hurt anything. My ring land cracked at 362WHP hence the engine build and why im pushing more power now.Hey would a gt3071 be okay to run on stock internals?
