Question FI 12a

Is it possible to install fuel injection from a late '80's 13b NA onto a '84 12a NA motor using the intake and all the electronics and harness's??

I know people have installed FI before, but I think that your thinking of the 84-85 Rx-7 thats fuel injected.

Search, you'll probably find something.

Why would you want a carb?? Carbs are a thing of the past. I like to keep modern with old engines, I FI my '49 Hudson flathead 6 cyl.

Not really. The FC engines run 4 injectors, primaries in the center iron, secondaries in the LIM. Secondaries come on around 36/3800 rpm. Running the secondaries as primaries won't fuel the engine very effectively. If you changed out the center iron to an SE one, made a new intake system with a tps, afm, and related sensors, run the SE ecu, then it might be possible.
