Seems a little overkill IMO especially as you really don't want to be running bigger injectors than you need.
The honest answer is that you should need to put 700cc into the BRZ injector scaling parameter, however I would expect this to be a bit lower based on what I've read. The best way is to run largely PI and see what fuel trims you're getting and adjust as necessary.
