I think most here will share the sentiment that you have come to the wrong place to look for this information. Its not that we dont want to be helpful, but i dont think anyone here has done what you want to. You really need to find a specialized NT 3000GT forum and go from there. If you are thinking that a T78 might be the right turbo for you with little or no prior knowledge on the subject, Id say you have much reading and research to do. good luck
