I am now aware of what i have to do to make my internals handle boost but I am still uncertain of what I have to do to make my fuel system do the saem. I can get silvia injectors pretty easy, the question is what i have to do to make my ecu be able to support a boosted engine. with my alltrac celica I just got bigger injectors and a fuel pressure regulator to sort of trick the ECU, However that is factory programed ecu that was made for a turbo application. the 240sx was never turbocharged stock so im wondering if I can or cant do that same thing that I did with my celica, just add more fuel and fuel pressure. what should I do? whats the cheapest route?
