Throttle Body ?'s

I am going to be replacing a lot of the intake part of my car in the next month or so and had a question on throttle bodies. What would be better for my car a 52 or 58mm throttle body. My mods are in my sig and I plan on adding a Moroso CAI, Granatelli MAF sensor, Trick Flow Elbow and then the throttle body. As for future plans I am undecide on the big 3, LT4, Nitrous or Supercharger, my goal is mid 12's once done.

I posted in your other thread on this right?
