View Full Version : Weber side drafts...

01-22-2011, 03:51 PM
So I have an oportunity to pick up the dual side draft weber setup for my 20r pretty cheap. Anyone have any experience with it? Is getting both carbs to work together a joke? Is this a viable setup for street driven vehicles?

It would go on a 1980 Toyota 4x4...

The 4age crowd uses them alot.

If you know where to find a twin carb manifold for the 20r id do it, depending on the price.

I think it even has the mainifold with them. My buddy wrecked his tacoma on an icy bridge and he needs to borow a vehicle for a month or so and I think he will trade in leiw of rent... A guy at his work is charging him $10 a day to drive an old ford so I think it would be a good deal for him. He traded some other parts for the carbs years ago and we were talking about swaping something for them before he wrecked.

which webers are they? Getting a manifold from LC Engineering is easy if one isnt included in the deal. You will also need the proper linkage to make them work. You can buy a carb syncronizer fairly cheap. I bought mine from JC Whitney to do bikes, but its the same for any multi carb setup. You sync the carbs using vacuum. Dialing in the jetting might be a little more difficult if they werent already set up for a 20R with similiar mods. Once jetted and dialed in they should be pretty much trouble free for a very long time, and are prefectly streetable. Ive run dual side drafts on my celicas in the past. You really need the right cam and I would recommend a good porting job to get full potential out of them.

Well he ended up finding a jeep cherokee for $500 so he decided to keep the carbs... I probably would have been sitting on them anyhow. I went ahead and rebuilt the stock 20r carb and it is way better anyhow. It will run well vertical or tiped over which is also a bonus over the webers. Would have been cool though...

20R carbs are crap for CFM though. I would buy a conversion manifold from LCE and drop a 22R carb on there, or even better find yourself a used 32/36

I've had the 20r carb run better on side angles than the 22r carb. I don't know why, but it does. Probably because it's more puny.
