964 Injectors

[1972_911T]

Does anyone have the stats for the 964 injectors? Ive searched all over but carnt find any figures, im trying to work out if these injectors will work in a 3.2, does anyone know?

Thanks Steve

I checked and the I have stats for some P-car injectors but not those. Keep in mind that the injector impedance has to match up as well.

Would it cause much of a problem to use one injector that isnt exactly matched. I have 5 3.2 injectors which are rated at 2.1 ohms and 243cc. I have managed to find an aditional one from 944 16v which is 2.2 ohms and 264cc that equates to about a 8% difference in maximum flow rate. Would it cause any problems to use this injector unitll I can source the proper part?

I've performed that exact substitution (1989 944S2 injector in 3.2) to debug a bad injector once so I know it fits and runs. Later ('91?) 944S2 injectors were a different impedance I think.
I would think it would make that one cylinder run a little rich which in turn would make the motor lean out the mixture under closed loop conditions i.e. the other ones would run leaner except under WOT.
I would think you could disconnect the O2 sensor to stop that but that's not great for the cat converter if you have one.

Thanks for the responce Chris, my engine actually doesnt have an o2 sensor as its a euro 3.2 so this shouldnt be a problem ill give it a try tonight.
