I am getting ready to change my fuel injectors. The question I have is 1) which size should I buy if I plan to turbo or SC later that will still run the stock engine fine for now. 2) Will a larger FI affect the performane of the stock engine. 3) Whats the biggest bang for the buck and recomendations will be greatly appreciated.

I dont think you can upgrade your injectors at all without having something to control them with like a SAFC. It can handle injectors up to 50% larger than stock.Without something to piggyback on your stock ECU, your motor will run rich cause it thinks its still using the samll OE injectors.

But why do you want to get new injectors? You probably should just wait til you go turbocharged.

I want to change them because I have one that is bad. I am planning on doing the turbo next summer. I only want to get about 250hp. But I do not want to buy new fuel injectors twice.
