I was thinking about swapping my stock carb for weber's what are the pro's and con's ? i live in indiana and don't have to worry about emissions?

I forgot. It's an 84 22r

get the weber 38, i have heard the 32/36 is about the same size as stock

talk to kyle 22r, he knows carbs

i like the weber 32/36 for its tuneability. it WILL make your truck perform better than any stock carb as long as it's jetted right.

however it can be a little frustrating tuning it by feel if you don't have a lot of experience, i'd recommend a wide band O2 sensor with A/F gauge(i need one). not quite as quick to adjust as something like a 4 barrel, you gotta pull the top off the carb. not too bad, just a little time consuming.

also i'd recommend a low pressure electric fuel pump, webers don't run too well(especially offroad) with a 7psi mechanical pump like most 22Rs have. mine puts out about 4lbs of pressure at the most.

32/36 with a e-pump

and you can get rid of a MASS of vaccuum hoses

I don't know what manufacture of carb is factory on Toyota, but my piss-on came with a hitachi carb, that was a pile! Everything was sealed and no tuning! I put a weber dgav 32/36 on, and the power was incredible, my gas mileage went from like 20 to 25 mpg. I'm not sure about off camber driving, but I do drive on some really rough roads (old fire break trails) and it does fine! Marlin used to have one on his motor until they put in the 3rz! So, that's gots to say something! The only thing I hate about mine is I have to adjust it in the fall and spring. I love mine!! Cleans up the engine bay! My electric fuel pump is at 3 psi. And webbers are simple to work on.

So Wait, thats 4lbs on the Electric pump right?

Yeah my buddy bought a Weber and he hated it. When we'd go wheeling it would die at only 30deg off camber. He bought it used and just threw it on (no Idea what kind of engine it came off of). He would complain how much he hated it. I kept telling him he needed to go throug it and tune and Jett it correctly and it will be better than his stock one. But he never did. Owell.

So who has a 38 on theirs? Courious.

i want to build a 20/22 hybrid for the celica with a 38 weber and 1 5/8 inch headers

How do these do on extreme angles

toyo487 · « **Reply #9 on:** Jun 26, 2006, 02:45:14 PM »

I have a weber on the 20R that I just bought. I have not run it yet but I'm hoping that it will be ok. How much fuel pressure does a stock fuel pump on a 20R put out? I'll let you know how I like mine when I get it running.

I've only seen one on the trail that was poorly tuned, so I'm not to sure.

Toy's used Aisin carbs, for the record.

I would leave it stock unless the carb is broken

TrikeKid · « **Reply #13 on:** Jun 27, 2006, 06:26:52 AM »

Don't want to hijack but is there any particular way I could ID the Weber in my truck? It came installed so I don't know anything about it.

BoG-ToY · « **Reply #14 on:** Jun 27, 2006, 08:47:25 AM »

dont know...Ive got three laying around.....Ive decided that my injection is staying.....but while on this carb topic....WHAT IS A WIDEBAND O2 sensor....and will it work with like an autozone A/F meter? or is this something totally seperate? Ive got my AZ A/F meter hooked up to a brand new o2 sensor on an older manifold where its on the manifold seperate from my puters junk, anyways, its always BOUNCING bad on the lean side while driving and while downshifting as a brake it leans out of the meter.....and help?

On engine braking, it should be lean. Cruising should be a little lean and hogging on it should be a little rich.

As for a weber, I wouldn't waste money on one unless it was free. Save up and go efi. I have 5 vac. lines on my stock carb. Doesn't have the response of a weber, but runs just as good. Better offroad.

Plowking · « **Reply #16 on:** Jun 27, 2006, 04:34:31 PM »

The weber would be my choice hands down, Like stated above alot less vaccum lines and it is a simple design that will run trouble free for years to come the only negative I had with my setup was the adapter plate bolts would come loose, make sure you use lock tite on all the bolts, Good luck

here's the intake you want to use with the weber

I have a 38 on my 20R, And the only problem I ran into was the fuel pressure, it doesn't like it too high. I also put an rv cam and some larger valves and a header and, it's still a 20r but it feels like a corvette compared to what it was.

Cheesemaker · « **Reply #19 on:** Jun 29, 2006, 09:54:00 AM »

Look at it this way! If the stk one works save up your money for an efi swap if you want to! I went to weber over a stk (hitachi-nissan) carb was that, I was having some serious problems with it, and nobody outside of a nissan factory trained mech was going to touch it! Nissan mech wanted as much as a new weber costs to even look at mine! And the factory rebuilds were like $1000! So, I bought a weber! Like posted before, I LOVE my weber! Ask Marlin or Bigmike about how the one on Marlin's toyota worked? If I remember right, Bigmike said that they would run the weber between the smog tests! And put the factory one back on for smogging!

skid · « **Reply #20 on:** Jun 29, 2006, 02:42:30 PM »

I believe on Marlin's setup, he was running the 20r head and intake. So, I'd take a cheap weber over a good running 20r carb. For a daily driver, weber if you want. If it get's wheeled, save for EFI.

I've got the 32/36 on my truck and i have rarely had an trouble with the steep angles. It only starts sputtering at at 50° or more. Only problem is that gas mileage is crap probably cause of too much fuel pressure though with the stock fuel pump.

Toyospearo · « **Reply #22 on:** Apr 17, 2011, 08:58:49 PM »

I have an 82 4x4 new motor, header, 268 cam, .060 bored and an old Asian carb I rebuilt a few months back. I also installed an electric fuel pump.
The Aisan carb is giving me trouble and I am interested in getting a Weber 32/36 or whatever you all recommend. I DD this truck and do some light wheeling but mostly it is my work truck. Do I get a DGEV or DGAV what is the difference? Do I need to modify or change my intake? Does the Weber come with everything I need to mount it up or do I need to order a mount?
What is involved in installing a Weber on a motor like mine...PITA level 1 or 10?
And about how much $ does the whole set up cost?

I just rebuilt the 20r carb and I like it... I know it's too small but you can run it on it's side and nearly vertical. I couldn't do that with a 22r carb. Who needs power anyways?!
