supra pump will be fine. if you expect your power needs to go up, consider getting the skyline pump or apexi's version (BNR33)

Walbro. Why spend several hundred dollars on a Supra pump when you can get a Walbro for about $100 and it will be more than enough for the numbers you're shooting for.

How about just replace your stock fuel pump wiring to guarantee 13.5V and you will get 350rwhp.

Assuming
15psi boost
15psi pressure drop in your stock fuel lines
40psi injector pressure (conservative, since it should be closer to 36psi)

350rwhp requires 161Liters/Hour @ 70psi.
