Ok, I've had my car a couple months now, I'm new to the F/I world and I have some questions. After searching for a while I couldn't find what I'm looking for. Currently I'm running a Perrin u/p, Perrin d/p, and ERZ catback. I'm ordering the Cobb AP next month and I'm interested in the VF34 as well. What all has to be done to upgrade the turbo? Bigger injectors? Bigger i/c?
