    fuel injectors

    Does anyone know what the stock fuel injector flow rate is?

    Not sure, but 350Z Nissan ones fit and are a good upgrade.

    Excellent thing to know! Now I have an idea of what style to use. Thanks!

    how does the 350z injectors affect acceleration/throttle response and the gas mileage??

    Need to ask a Thai owner, most of them run them so the can use E85
    My guess would be milage higher since they are larger than standard.

    Badly, I'd imagine, if nothing else is changed! The flow rate of 350z items will be somewhat greater so it'll squirt more fuel at a given fuel rail pressure and injector pulse width - Meaning excessive richness unless the fuel tables are trimmed accordingly. At idle the engine will be in closed loop so the ECU will adjust (as best it can) on o2 sensor feedback, but only so far. In open loop (which is usually most driving conditions above a certain [usually rather low] engine load / throttle percentage), it'll be pretty nasty unless the ECU is reflashed or a piggyback computer is used.

    On another note - In the past, Mitsubishi have used Denso injectors and the flow rate in CCs is usually stamped on the plastic.
