    650's should be more than enough for 325.

    you have peak/hold injectors stock in the motor.

    it depends on what computer you are using as your hondata base for which injectors to go with, and or if you are running a resistor box or not.

    basically,

    peak/hold = needs resistor box
    saturated = doesn't need it.

    the car engine is likely pre-wired for it. look for it. looks kinda like a heat sink, 2x3x.5 inches coming off the fuel rail wiring.
