    How much power can the std fuel system on the 1GR handle before you have to start to up grade fuel pumps etc?

    The stock injectors are only 295cc, so your not gonna get a lot of power out of that.

    The injectors are going to be the first bottle neck. Upgrade those and the rest of the system is good up to over 300rwhp.

    Upgrade the injectors and fuel pump, and you can push over 400rwhp. I know of a turbo'd truck on 670cc injectors and a 255lph fuel pump dyno'd over 400rwhp on 35" tires and almost 500lbs of torque.

    If all goes well and I can use the x-one with the TRD s/c,TRD cai, 2.85" pulley, E85 injectors and full exaust, do you think I will need to upgrade the fuel pump with this setup.

    I would recommend doing so yes. Having too much fuel, is just enough. :thumbsup:

    +1- Fuel pumps are "easy" and like Xr said-being able to push more than you need- Just right!!
