hey guys, im lookin to make my own custom turbo setup, i.e. buy a rebuilt turbo, then have the piping done at the shop, buy a used i/c online, etc.... so anyways the question is what is necessary for the turbo system to work safely, im just lookin to run about 7psi on an either t3 or t3/t4 turbo. So far ive thought up, turbo, piping, 370cc injectors(this a good size???), i/c, modified ecu(do i REALLY need this?? its like 600 bucks!).....what else is necessary? BOV and wastegates arent necessary and i could just add them on later right???
