or 1050cc injectors if I just plan on going 93. I know obviously dual 450 FP and 1300CC if I plan on going e85 but I really just don't know if I will. I know it'll help cooling and more power. I guess I gotta flip the coin on it. Is there anything else needed besides dual 450 FP's, 1300cc injectors and flex fuel kit?

What silversleeper said. We're just saying spend the money once if you think you might ever want to go bigger, that's all. If you want to stay under 750rwhp on 93 octane, then the 850's will be fine (although the ID1050x's would be my choice).
I will argue that you DO need a BAP, though, even on 93. You can technically run without it, but your fuel pressure will fall to the low 40's or high 30's at the top of the RPM band. The ECM will compensate with injector pulsewidth so you don't go lean, but you will lose atomization and power (as well as pushing injector pulsewidth closer to the maximum). Much better to have a constant 65 psi at 5000+ rpm as opposed to a pressure that falls down to 40-ish.
