Well my 1g manifold has cracks in it. I tried searching on here for some good cast manifold reviews and what people use for mitsu housing turbo. But could not find anything at all. So what do people upgrade to that are on a budget. I will be running a SBR G60 turbo and a punishment racing 02 housing with a tail 38mm wastegate. What would be a good cast manifold. Any help or reviews would be great thanks.
