Off road carbs
 
Was just curious to see some of your guys suggestion on carburetors for the 4.0... Mostly off road use

tigerblood 05-16-2013 07:03 PM

mc2100/2150

impulse250 05-16-2013 09:14 PM

ford/motorcraft

Tyler92yj 05-16-2013 11:21 PM

ive seen alot of jeeps with carbs die on the trail or on a hill climb efi is the way to go

Keymo 05-17-2013 12:59 AM

If the OP has a 4.0L should that not be injected already?

impulse250 05-17-2013 07:53 AM

I think 92 or 93 was the year they went Injected on the 4.0. Not sure though

Keymo 05-17-2013 07:56 AM

Ah! Sorry! I wasn't aware of your model year... My bad! :D

impulse250 05-17-2013 08:16 AM

Lol! It's all good! Ya unfortunately my 1990 is carb. I had a 91 a few years ago n never really had issues on hills with the carb, Only if I was on a really really steep hill it would cut out some

Keymo 05-17-2013 09:32 AM

Yeah... The MC 2150 is definitely an AMAZING carb. Have one on my J-truck and there's this mini-hill climb area outside of town that people do - had her at some INSANE angles (uphill) and she's never cut out on me. I'm trying to find one (not one of the expensive ebay ones - I'm all about rebuilding it) for my YJ. :thumb:

impulse250 05-17-2013 01:19 PM

Can u still by the carbs brand new?

You can off eBay.... But they're expensive - like 150-280 for the "buy it now" ones... Better off finding one at a junkyard and cleaning/rebuilding yourself.. You'll save like 100 or more... That's what I'm holding out for! Haha!

impulse250 05-17-2013 01:27 PM

Hahahah. Ya. Ill have to try that. What are those carbs usually on? Vehicle wise ?

impulse250 05-17-2013 01:28 PM

Also. Will I need to buy any mounting kits or anything to install it?

Yeah... Theyre on most 70s to early 80s fords (I THINK)... I have a list of the specific models I'll try to find...

And yes. You'll need the gaskets and a "large 2barrel to small 2barrel conversion plate" (theres also a specific carb conversion name but i forget right now - ill look it up in a minute) i know you can get them from advance auto and other various places...

Keymo 05-17-2013 01:57 PM

Okay - here's the vehicle list:
70's and early 80's Grand Wagoneer

Ford/Murcury Vehicles from 70's:
Bronco, Comet, Cougar, Maverick, Meteor, Montego, F250, Ecoline, Falcon, Fairline, Mustang and Torino

Early CJ's with the 304 V8

Specific ENGINES that came with the MC2100/2150 Carbs:
1975-1977 2.8L V6
1982-1983 3.8L Essex V6
1973-1983 250CID 4.1L I6
1973-1983 302CID 4.9L Windsor

Keymo 05-17-2013 02:01 PM

And that conversion plate is specifically called:
"2Barrel Roshester to 2Barrel Holley Adapter"
The part number for Advance Auto is SUPPOSEDLY "P/N 1937" Though I haven't CONFIRMED this....

impulse250 05-17-2013 05:12 PM

Hell yes. Thank u! I actually wonder if mine already has it on it bc the previous owner out a bigger Holley carb on it

Nubby55 05-17-2013 05:36 PM

if it's got a holley on it, that what the Mc 2100/50 is a copy of, it's a 350cfm or a 500cfm, ether one is a fine carb for the 4.2. The 2150 is about 350cfm, honed and polished you can get about 400cfm out of one.

impulse250 05-17-2013 06:07 PM

Really? From the pix on the Internet of the 2150 this carb on it now looks nothing like em lol

A friend of mine gave me his from his bronco and i know it's a MC carb but don't know what one it is... I have a weber on my 4.2 now an hate it!! There are 2 adapter plates under the weber now so I'm hoping that is also the one that fits the MC

Keymo 05-21-2013 12:21 AM

LUCKY!!! Haha! I need one of those babies!! :p
I think I can see the tag in the picture... But there will be a tag or stamp somewhere on it with the model number...

Jeep went to EFI 4.0 in '91. B4 that it was a 4.2 and had a carb. Get Howell EFI conversion kit, cheap compared to other brands, at wound $1,200. A good carb will cost you about $300.

Beachcruiser 05-21-2013 01:54 PM

My carb cost me 90 bucks to install (total, with self rebuild, adapter, etc).

The most common application for the 1.08 ventur1 2100/2150 that works best on the 4.2 Jeep is from a Ford 302 (68-81, used in everything from Mustangs to F trucks)

Not only can you find them on Ebay for as little as 45 bucks, but keep an eye out on Clist, local 4X4 forums & mustang sites.

Mewing8 05-21-2013 03:50 PM

Go with the injection, yes cost more but reliability and ease of use are worth it, not to mention fuel mileage and power increase. It will be the best mod you will ever do!

X2, but if some one don't have the extra money for the injection,the 2150 is a good set up, I like the old Carter from an old CJ7, late 70s. No stepper motor and no Mods. or adapters to cause leaks, jetted right, right out the box, a bolt on and go, after idle air adj. set your timing @ 12 BTDC :thumb:

I have the 70's Carter without a stepper motor.:D It's alright... It's starting to fade on me though (not sure when or if it's ever been rebuilt)- either need a rebuild or upgrade... My YJ didn't like the timing set at 12BTDC though - it was too much. Had to back her back down to about 8-9... She seems to like that more. :p

Anybody right off the bat tell me what carb this is?


Attachment 266785

89Saharagreen 06-29-2013 03:56 PM

Is this a joke it says Holley on the front?

impulse250 06-29-2013 04:05 PM

Lol. Somewhat of a joke lol. Good job!!! Actually I'm curious what model by Holley. I'm not to sure how to distinguish that....
