I am running a wrx block with perrea pistons, port and polish w/ 1mm overbore...

I will be running a VF39 in the next few weeks. My question is, what fuel pump and what injectors should i be running? i can get the turbo with the sti fuel pump, but the injectors i have to get seperately (top feed vs. side feed). is it safe to run the sti fuel pump? should what injectors should i get?

oh, and of course, the money question....what kinda power should i expect? i have the basic mods (up/down, no cats to catback and ECUTek stg 2 dyno tune, which i plan on getting redone after the install)
