Has anyone used the turbo manifold for the 7mgte from suprasport? I was just wondering if its worth the performance. My exhaust gasket is burnt out so im lookign to replace it and while its off put on a new mani. And another question? Im running the HKS t04e .60 trim and i was wondering about the added wastegate option. dosent that turbo have a internal waste gate? would buying a new turbo manifold with a 40mm wastegate flange and a waste gate with a internal one on the turbo do anything weird lol?
