Carburetor replacement

Problem is, it is not as simple as fitting a throttle body, the carburetor mixes the air and fuel for the engine, the throttle body on injected engines is just an air valve, fuel is delivered via fuel injectors, you will regular a new inlet manifold, new loom, new PCM O2 sensors, air flow meter, throttle position sensor, numerous other sensors, basically, carburetor engines cannot be converted to EFI even doing a conversion to an injected engine require much more work and cost than just fitting the engine.

If you want to adapt a factory system you would be better off buying a complete parts vehicle with a running engine, the factory service and wiring manuals for both vehicles, and then moving all the required parts over. If you go that route stay away from the more modern trucks and get an early TBI system as they are simpler.

There are a few stand alone injection systems made in the aftermarket that "bolt on".

I had an early Holley Pro-Jection system. It worked somewhat better than a carburetor but because it did not monitor the engine real close it had its issues as well.

Good luck with it.

How about getting a nice Holley then use the techniques in this link to tune the puppy up right!

I like the Holley, its adjustments are simple, it is easy to get into and parts are locally available.

I have tried might near everything with my Jeeps over the years to improve the fuel situation. I have had nothing but CJ's since I was allowed on the asphalt in 1981. I was not going let it whoop me either!

Improving on my present 1977 CJ5 Jeep with a 258 straight six cylinder, I bought a Offenhauser four barrel intake and a 390 Holley, as I could never get a whole lot out of my original two bbl Carter BBD or the Weber I replaced it with first go 'round

I gained two mpg (with my normal grandma-like driving) and I have power if I need it.

The link I gave you helped me out so much with tuning the carburetor!

Let us know how things are working out.
