With a 913 pump calibrated to max with the rack set at 18mm to keep it out of the retard notches, and cut delivery valves and holders and stock lines I have done 612rwhp with a s400/s300 hybrid. I am fairly certain the 913 could do the 500rwhp with minimal mods, but I don't think it could support a 1000. I think a tuned 160 or 180hp pump might be enough, it would be real close.
I would do ddp4 injectors, maybe get them to make some slightly larger for the spray, get a 66 or 71mm S300 with the big turbine, and add an external extra wastegate, get a 160hp pump and max it out with cut delivery valves, 4K springs, opened up holders, do a bunch of head work and a camshaft, stud and fire ring it and you should have a recipe to do the 500rwhp pretty easy. I don't have hardly any experience with nitrous with that setup, but I have seen similar setups and they were right at the 1000rwhp mark.
