the 32/36 will be more economic. that is what i use for my DD...i mean i still only get 10 or 11 mph. lol. but it has two ventrilli's, one is 32mm and the other is 36mm. the 32mm is the main one and on normal driving it will be the only one in use. but if you floor it the 36mm will open and it really does throw on the power on the engine. so it is there if you need it. i love mine and have had no problems with it...its easy to tune and work on. can't help you with the 34 though.

What are you going to use your jeep for? If its a daily driver/weekend worrior I would go with the 32/36, for the reasons stated by mean90yj. If its going to mostly be a trail rig then go for the 34/34 because it has a little more low end/low throttle power than the 32/36.

It is going to be a Daily Driver.
I was looking at getting the kit.
Sounds like the 32/36 is the way to go for me.
Now I just need to find the cheapest kit.

$379 the cheapest I have seen so far.

i think you mean I6 not v6. i have a 34/34(interco) weber and i must say it did give me more torque.mine is also progressive.past half throttle it starts to open up the second barrell.i got it thinking it was just going to be less problems but it did improve throttle responce and torque.

I've got the 34 and love it. Bolted in with no issues. I still have a fuel pressure regulator but haven't installed it yet. I may not. It seems to be running fine without it. The throttle response in 3rd gear was night and day different.

I don't know how much fuel you might save with the 32/36 but who cares. You are driving a vehicle with the aerodynamics of a brick so I doubt that it will really matter in the long or short run.

Well the 34 is $299 with free shipping and the 32/36 is $379. For $80 maybe its not worth getting the 32/36. But since its a DD maybe it would be nice to have the extra power if needed.

Sounds like either way they are a good choice.

Does anyone know if one is easier to install then the other??

Thanks

If you don't mind doing a little carb rebuilding you can pick one up for about $100 on ebay. The adapter plates and throttle kit is about $70 from Redline, rebuild kit about $20. The 32/36 I got came off a BMW 2002 and was jetted perfect for my jeep, according to all the information I gathered here for jetting. So for about $200 my jeep is running great.

I didn't do the Weber (MC2100), and I'm no mechanic either - I only started learning anything about auto repair/mods when I bought the Jeep a year ago. I had never swapped a carb before, and it took me about an hour and a half (split between an evening before dark and the next morning) from start to finish. I had already done the Nutter bypass, but that's only an extra 45 minutes or less.

Elvis did a GREAT write up on the install. The directions that come with the weber suck!
