Well, after collecting most of the parts for the project....I'm still not sure about how to get more fuel to the engine. If I go with the FMU I have to stay with the stock injectors, If I go with the S-afc I can upgrade to the vr4 injectors. Any oppinions on the matter? How do you open up the waste gate actuator(looks like a disc shaped box) and change out the spring? I want to set both the turbos to open at 5 psi, then I can just get a manual boost controller to up the boost.
