fuel mods help for nos
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.

you can run a 50 dry shot without upgrading anything, as the added fuel curve is there to support it in the factory tune. Past that, you would need to start upgrading your fuel system and rigging a wet shot system.

With a wet system, plan on fuel pump at a minimum. I'm pretty sure this is the one Garm is running...http://perrinperformance.com/product...bro?category=7 The wet kit will use wet style nozzles, meaning the fuel and nos jets are in the same nozzle. In other words, you don't need to mess with the stock injectors or fuel rail, since the added fuel won't be being added through there. Also, methinks you are going to need some type of engine management, or else all that added fuel might cause the computer to lean out the injector stream, hence killing your engine.

If you're just planning on jetting your nitrous for around 50 hp then you really dont need to upgrade anything Imo . From what I've read people spraying on 1st gen xb's are spraying 35-60 hp without problems and are only seeing about a 1psi drop in fuel pressure when spraying . I am thinking about installing an autogear fuel rail when I install my direct port no2 to have a little extra fuel

Seems like a lot of money, you could just T the line short of the rail and plumb your nos dist block.

Had a mechanic take a look at it for ya...he said that you can just T the line...the computer will see the drop in fuel pressure and should change the duty cycle on the pump to adjust. He said stock pump should handle depending on how much of a shot you are running. He also said Ken Belle makes a product that makes it so it only sends more fuel when the switch is on and it's in WOT. He says carry a fire extinguisher at all times.
