ive got a question for you guys. im somewhat new here but not really so if this has already been covered, let me know. please dont be sarcastic. im planning on doing header, high-flow cat, new exhaust system, intake manifold, throttle body, already have the intake. i know that when you do a turbo you have to upgrade the fuel system to even out the air fuel ratio. i was wondering if i would have to do that since i will be bringing in more air or if its not a big enough increase to change anything to cause me problems.

No.

Check out what bulletdsm has done. I believe with the new tune on the 12.5:1 motor he has just gotten up to 87% duty cycle on the stock injectors. It's safe to say that his motor is flowing more than yours.
