I have a 93 5.0 lx coupe that I am putting a vortech v-2 s-trim w/aftercooler on. It came with a t-rex pump and FMU. I need to know what else I need to put on it before I get it tuned(engine wise). I also purchased a trickflow upper and lower with a 75mm accufab TB and egr plate. Along with BBK long tubes, x-pipe and 40 series flows. What size injectors should I get? Can I get them off a donor car? Its my first 5.0 mustang so I need a little guidance.
