Go to the auto recycler in your area with some tools and pull them out of a few doner Neons, it's up to you if you actually pay for them or not.

I may have 12 that I would be willing to sell. I just picked up 3 sets of 4 @ the local junkyard and in the process of flushing and flow testing them. I have some concerns that the flow rate of these injectors is too much more than the flow of the stock injectors to help with my gas mileage. I can see the better spray atomization when comparing the two, but going from 20.5 lb/hr (2 stock tested at Room temp, 14 V @ injector, 100% DC, calibration fluid) to 24.5 lb/hr (12 tested, same conditions) for the ...703 injectors seems like a huge adjustment for my OBD1 Cherokee to make.

I would like to hear from anyone who has made the swap and has real data to backup their findings to discuss how this pans out in the ECU/engine.

For specifics on the data or future sale, please PM me.

Thanks, David

Default Adjust Fuel Pressure?

I forgot to mention that the test were run at 3.00 bar fuel pressure (~43.5 psi).

Does anyone know an inexpensive and an accurate way to lower the fuel pressure 20%?

Thanks

I was at the JY. Pulled 8, kept the shiniest 6, left 2 there. No idea how many were available. Should I be harvesting them?
