I have a friend who has built several engines, but mostly mitsu 4G63s. He was actually the one who found the Z and is excited for me to get this one. He has also been doing a bunch of research for me as well. I am pretty lucky to have a bf and lotsa friends who can teach me how to work on it myself. I already helped my bf switch out his cams in his evo and, learned how to install an intake and boost controller. I am getting pretty knowledgeable and I just want to thank everyone on here who has been very gracious and helpful in answering my questions, and I know it is going to be expensive but I want another sweet car.
