Not sure if the stock fuel pump can support that or not. I would guess not.
Its not really that hard, you have to run switched 12v to your new fuel pump and supply it with fuel. We had to do it all the time with carbed motorcycles, so its not terrible, but it is more work. If you call the NX tech guys they can lay the whole procedure out to you, and tell you what you need to buy.
I just thought of it, if you have to put a seperate bung in the tank to pull the fuel, that will be a PITA, but I"ve done that before ,too. But it means dropping the tank and doing it. Call the NX tech guys, they may know, or you could do a small seperate fuel cell as well, and draw from that. That may be easier.
Speed is only a matter of money; how fast do you want to go?
