Fuel Pump / Injectors Question

I have an '01 GT that is pretty close to stock currently. My plan is to slowly build up and eventually put in a custom twin turbo kit. Right now I am looking around for things I can do to my car that will help me on my way, and I was wondering if I upgraded the fuel pump and injectors right now, would it be ok? I would like to put in a 255lbh pump and I am not quite sure on the injectors, put some pretty heavy duty ones. Should I wait til I put the turbo kit in or can I do it now? Thanks for the help guys.

I'd wait, till you get the turbo going. Not worth it till then.

Also along with the injectors you need a MAF calibrated for them. But yea I would wait, really no need.
