injector size?

what are stock injector size on the 2.4 ? wondering if a set i have are worth keeping for a project.

175CC are stock units

Are you sure they arent 275cc? Usually with other mitsu injectors, the ID mark is also the size. The service manual is showing the ID mark as N275H. Also, 175cc seems smaller than I'd expect for the hp rating of the engine.

Yeah, my bad, 275's what was I thinking....holy thread resurrection

Sorry for the resurrection. I was requested to by someone that was unsure which of us were correct. Thanks for the follow up.

My whole world has been turned upside down.

Is this too much injector for a 2.0 and a 2.4 computer?

I think it all comes down to what resistance value the injectors are. If you upsize your injector capacity, it 'should' only run rich until the ECU retunes itself to adapt to the new injector flow (which it should do fairly quickly).

Incorrect, there is a value in the ECU firmware for the injector size, it need to match the ones being used, the ECU will not "adapt" to what is installed. It is making decisions based on sensor input and fixed values. it cannot compensate for major variations(I know, bummer).

There a basically 2 kinds of injectors electrically, High impedance and low impedance. the 275's are High impedance, 450's (Stock Turbo) and larger are typically low impedance, hence the need for the resistor pack to compensate when switching types.
