just curious ... i am working on a buddys ford and we have decided to go carburated... to eliminate alot of the computer issues and wiring that we are having due to a new motor that we are puttin in ... that got me thinking about possibly doing a carb swap with my jeep... has anyone done this before? im sure someone has lol ... i cannot find a manifold online anywhere ... help is appreciated in advance

You won't find one easily - there's no such thing as a carburetted 242ci from the factory, and no-one has (yet) made an aftermarket carbed manifold for it.Originally Posted by '96XJSport

You may want to pillage around Clifford Performance or HESCO and see if they have something that can be adapted, but I'm inclined to doubt it. Besides, OBD-II is miles better than OBD-I. What trouble are you having?
its not so much that im having troubles im just pretty bored to be honest with you ... lol i do have a bad trans control module an so i had to test alot of wiring to come to that conclusion so it just got me thinking back to my old chevy k10 that i used to have and how much simpler carburated rigs are

Well, everything, including the trans is electronically controlled. So how would you control the trans or the fuel? How would you pass smog? I'm pretty sure that you would have a CEL if you unplugged all that stuff. And most palces now do a OBD test with the smog. If you want something that is less complex. Try an OBDI or Renix XJ.
If you want a carbed or TBI motor, my suggestion would be to buy a different vehicle. Up until the early 90's the Wranglers were carbed.

they make stand alone trans conrollers and i dont have to pass smog where i live as well... i havnt made up my mind yet but im still thinking about it ... it would be something different thats for sureOriginally Posted by Metmknice

Just because you can do something, doesn't mean you should.
Your local requirements may be one thing -- but it's a federal offense to tamper with emissons in that manner.

If you like simple stuff, get rid of tank, pump, a ton of wires and sensors, injectors, carb, fuel lines, filters, control module, everything and install a propane kit.

Carb's aren't necessarily a step backwards...depends on the purpose. A well tuned and maintained carb can get mileage and emissions just as good as EFI. My 65 mustang has better emissions than my wife's 99 mustang. The difference? I have to retune the 65 every season when it changes temp more than 20*. I have to rebuild the carb every 2-3 years to keep it tip-top running order. I've never touched any part of the EFI system on my wife's 99 other than cleaning the throttle body once a year.
As far as converting from EFI to CARB, unless you were making a track racing car, it would not be a good idea generally. Carbs can be finicky to altitude changes (bad for off roading), seasonal temperature changes, etc. You'd also have to change out the fuel pump since your EFI fuel pump will over pressurize the carb and blow out the seals.
Carb's are any more of a PITA than EFI if you are familiar with carbs. I've spent countless hours hunting down fuel delivery problems on friend's cars...I can rebuild a holley 4V carb in 2 (1 if I actually pay attention the entire time).
But in the end, i would keep with EFI. It is so nice to just turn the key.

In order of complexity of service (high to low,) I'd go with OBD-I/OBD-II/RENIX.
OBD-I wasn't really standardised across the industry, which is why it's the worst of the two. OBD-II follows an industry standard set by SAE - they took over from CARB.
RENIX is often perceived as difficult, but the lack of OBD makes it easier to work on - if you're used to doing your own thinking (I am.)

I am not talking about the difficulty to work on, i'm saying it is electronically more complex. It has a couple of sensors more than the OBD I/II.Originally Posted by 5-90

It was created by Renault and Bendix for formula 1 cars, but then was dropped for it's high complexity.
from wikipedia: ..."The Renix system has more inputs than the later Mopar system and in some ways is more complex"...

PS: everybody should read this it is very interesting.

The thing I do not like about carbs is they do not run well on angles and tend to die easily.
