Alright, after browsing the forums and what not i have not found my answer. I Assume the EJ22 block built and turbo'd will be better than a EJ25 turbo motor, but When I do the swap I want as minimal down time as possible. I thought about I-Speed but I dont know that much about their prices and down time. My intended swap right now is a EJ25 turbo built. I am worried about wiring.. I heard theres a lot of wiring differences so I am thinking about Running a haltech or something of that nature. Does anyone have an opinion on this?
