Alight I'm a little stuck because I'm bought a 1j with no turbo and a cut harness. I'm really didnt care that it didnt came with any turbo because I'm going single with it. Ok can some tell me how to install an single or were I can go to see a diagram or pic guiding how its done. Im stuck I see to oil feed lines but no return line and what do I need to by pass for the coolent system. Thanks also I need to find a complete diagram of the vac line as well
