I'm curious what impedence the factory injectors are on the fox 5.0's. And are they any different from the motors pre 89? I think thats when they started the MAF's. I'm pretty fresh to these and I'm debating on a turbo fox project. I hear I can use the injectors that are on the FC3S Rx-7's (86-91) they range from 460cc and 550cc (about 42lbs ish to 52lbs ish I think). Depending on what year, the rx-7's run low impedence and high impedence for both sizes.

I tried a search and I'm reading plenty on the injectors and what people are doing to use both but not really an answer on what I'm asking, whats factory?
 
Factory is high impedance. As far as i know, only the 2.3L turbo Mustangs/thrunderbird used low impedance injectors

If you measure resistance of the injector, it's approx. 14.4 Ohms across the terminals
