can i run all the fuel management that i would use for my turbo before the turbo is even put in??
ie, Bigger injectors, walbro 225 fuel pump, and a fuel pressure regulator, with the Apexi S-AFC???
if i can, what will i have to set the safc to???
what are the pros and cons to doing this?
i wont be running it for long... im just gonna run it before i put in the rest of my turbo...cuz i wanted to get the fuel out of the way first...

There is no problem with you doing that.  The pump will recirculate any unused fuel thru the return line.  
The Injectors will be handled thru the AFC.  Generally, you need to get on a dyno to tune the AFC, but you should be able to tune the injectors down 37% to run the same 280cc of fuel as the stock injectors provide.  Also, the pressure regulator (RRFPR) wont increase the fuel pressure without boost, so that would be fine too.
