i dont think its the rwhp you should be worried about. i think its how much boost you plan on boosting.
When to upgrade fuel pump
At around what RWHP level do the mkivs need an upgraded fuel pump?

The best way to confirm this is with a fuel pressure gauge and not go by hocus pocus.

ANYWAYS...
stock pump will flow enough for around 500rwhp. at that point you will need more then just an upgraded pump though, you'll need bigger injectors, rail, lines, ect on a supra.
