All Mopar \6 Fuel Injection?

Regardless of the parts sources the fabricating is pretty much the same. I don't know if the intake runner spacing on the 4.0 jeep engine is close enough to allow the fuel rail to be used, but it would be a nice source if possible. You would still need to aquire/make a injection intake. Crank sensor is generally handled using a toothed wheel on the crank pulley and a custom bracket to hold the sensor. Cam sensor I believe is being handled by cutting down a slant dizzy. I don't believe the factory pcm is very programmable but I could be wrong.

This is one of those places where I think any car can be a suitable donor not just mopar stuff.
