Weber on 20R Q

heep70 · Oct 24, 2006

Do Weber carbs work well with 20R?

Any issues in climbing or decending steep hills?

I here Weber has made longer quench rods (I think that is waht they are called) to help in flooding issue while decending a hill.

Give me your input. :cheer:

iF YOU put one on greg--I will have to beat you silly

Don't do it man....

What crash said. If your a highway driver which you aren't sure there great.

I have one, and off-road sucks nads. Keep on the throttle or be prepared to turn over the engine multiple times on hill climbs.

Now I've been able to climb pretty much anything but if your not keeping the fuel sucking then well basically your engine will die lol.

Dam gravity fed POS

Do Weber carbs work well on anything? Yes. The big honkin' dual throat side drafts work great on a warmed up engine, but only at full throttle. All other Webers are ****.

IMO :flipoff:

I had a weber 38dges(both barrels are 38mm and open up at the same time) on my 22r/20r hybrid engine. Just like the others said, they work fine, as long as you keep it fed.

Ran that carb and a 40mm on a C-series OFFY intake. fast lil thing on the road--off the road--what a pile o crap...

OK, I think I will try something else.

What is a good carb for my 20R offroad?

smalltowncowboy · Oct 24, 2006

i see all these negative remarks about webers. i ran one on my 22r/20r stroker, it was a weber outlaw. never had a problem offroad, on road, could idle up a rock face and never even sputter. so i dont know if it was just how i built my engine or if it was the carb but i never had a problem.

i used to take that truck everywhere, snow, mud, rocks, rivers.

Is there a way to adapt a Motorcraft to a 20R?

stompinjab1 · Oct 24, 2006

Yes you can adapt anything with $

CrustyJeep · Oct 24, 2006

How about TBI on a 4 banger?

Rcbro · Oct 24, 2006

LMK what you end up picking. I'd be interested to see how it works.

Mine is like a 32/36 or something like that.

could go EFI if he wanted to spend the extra money. but ive also never seen EFI on a 20R might have to go up to a 22R for that.

I got a weber atop my 22R/20R. Tons of power but its doesn't run very well when I point the nose of my truck up. If i go on a hill climb assault and dont keep my foot in it, it will most likely die. On the other hand, sidehills or even steep declines and it runs just fine.

I want to put some kind of stand alone TBI on it. Will a throttle body off a mid 80 chevy 350 be way too big for it? What else??... I cant use toyota EFI because i dont want to give up my 20R head.

EFI doesn't really care. Besides, the factory throttle bodies aren't that big anyway. Least of your worries.

The real problems would be adapting the throttle body to your manifold (pretty easy, even if you had to custom cut an adapter plate), building a map for the ECU (obviously custom), and a distributer. Everything else should be pretty straight forward I think.

Thats easy. Just get an efi off an 84 celica and swap the head over.

What do you think of that stand alone throttle body injection system that holly makes? Reason i ask: It doesn't have much computer input. I think an O2 sensor is all...

Get a megasquirt control module (do a search on google) and a 2.2 gm throttle body...

Now that I have been talked out of a Weber I think I will deal with my stock pile of carb. I might have found the fuel eating problem, but the problem with it dieing on decents still lives. It also idles higher on inclines.

What do I need to do with the float to help correct the dieing decent problem? :beer:
