And plus if you do spend all that time doing that, when you do achive your goal, then what? But i say save the turbo and anything that you have bolted on to your d series engine, that would work on a b series and if you can sell your engine and since your on a budget get a b16a CLICK HERE it's the one im getting cus i dont have money either. Then you just need a differnt manifold and you already have a turbo and intercooler and the greddy data thingy. And all of the stuff you saved from your last engine. But good luck on your efforts.
