fuel mods help for nos

[cruz-gsr]

so here is the deal, im a student at UTI and i have talk to some of my teachers about installing nos in my yaris and they told me i have to upgrade some parts of the fuel system first.

I need to install a inline fuel pump or replace the stock pump with a higher output just to meet the demand of the fuel needed. I was thinking to replace the fuel rail and use a high pressure regulator.

Any ideas. I just don't know where to start looking.
