is it possible to run high imp injectors on my 96 cav that runs low imp injectors

Why would you want to? Usually guys want to go the other way because low impedance injectors are cheaper.

No you can't ... You can run low Imp on a high imp but not high imp on low imp cars

i should did little more checking before i bought lucas 38# injectors out of a late 80's early 90's stang

Not to be rude, but this is the opposite of what is true. You can run high on low, but not low on high. When you run a low impedance injector on a high impedance injector driver, the resistance (impedance) is lower, so to maintain the same voltage more amperage is needed. This additional amperage can fry the injector drivers.

This is directly from Ohm's law, V=IR (voltage = amperage X resistance).

Here is a typical high impedance: 12 volts = 1 amp X 12 Ohms

And low impedance injectors are around 6 Ohms, so to maintain 12 volts you would need 12 volts / 6 Ohms, which comes out to be 2 amps. You have now doubled the amount of current needed to operate the injector, which can really f some stuff up.

Sorry after I reread what i had posted a few min ago I went DUH .
I had it correct in my head but i didnt post it correctly . I have done this rewiring of the injectors before on a fox body .
But for some reason i had it backwards when i posted .. Sorry again ... And good catch Wagonwes

It's cool, just don't want anyone to dig this up and make a wrong decision.

so it is possible then what is need to do the swap?

Plug them in. You may notice some slight issues, but they will work. It is best to use the injectors that the car is designed for, but there should be no major problems.
