How many Weber carbs can we use?

[88Accord-DX]

I've searched through many threads on webers & haven't seen any answer. Yeah, 32/36 - 38, DCOE, Holley #5200 & such. My question is, can you use different weber carbs like 32/36 DGAV-33B1, or even DGEV, DFEV for that matter? I'm looking into getting a weber some day & would like to know how many options there are. I'm not sure if the electric choke off a DGAV can be switched to manual like the DGV 5A carb. I appreciate GOOD advice, not some post whoring B.S.

from wut i read from a guy over at prelude power he has a 38/38 and say its the best carb for a built a20

[hondaman1986]

ok so im ignorant in holley carbs so what kind of carb is the holley 5200?

2bbl 4bb and how many cfm?

[2ndGenGuy]

Dude you can use any of those carbs. Any DGV or DGS carb shares a common mounting flange. I'm sure there are others that do as well. So long as they have that same base flange, you can buy the adapter plate and bolt it right on.

Most of the parts are interchangeable between carbs. I'm pretty sure the chokes on any of the DGV series are interchangeable. Of course there are hundreds of variations of each carb. Some are built for different car manufacturers, some are upgraded and revised over the current year. Thing is they've been making carbs forever, and so there are revisions and changes. The one thing they should share is that mounting flange.

They even have some crazy new carb out that's like a 36/36 or something that you can use as well. It's supposed to have the economy of the DGV 32/36 and perform as well as the DGS 38. But it shares many of the components of the other carbs.

As far as the performance sidedrafts and other downdraft carbs, you're going to have to fab somethign to make them work. Many people do the DCOE sidedrafts because they go with inline engines so well. They pretty much bolt onto the side of the engine.

This page should pretty much explain what I mean.

Anyways, hope that was somewhat informative. I suggest picking up a Weber book off of Amazon. There's books on performance tuning, economy tuning, and just general how the carbs work. They tell all of the different types of carbs and explain the background quite well.

They seem very complicated and daunting at first, but once you get the hang of them, I don't think they're so bad. I've yet to rebuild one, but I'm looking forward to it.

so is the holley 5200 basicly the webber 32/36?

[88Accord-DX]

Yeah, Holley #5200 is the 32/36. It was a version under license from Weber for Holley to manufacture it.

Guess I will look into hooking up a manual choke on DGAV or similar carb. Thanks 2GenGuy for the input. I was thinking they were just udated version of the same carb.

Here is some info on the 5200
http://www.surpluselectron.com/aaron/holley.htm

Holley apparently rates it around 280 CFM


The DGV DGEV DGES lables after the 32/36 or 38 are mostly variations on the type of choke setup, otherwise the carb is the same.

yea I'm looking forward to getting mine done, these su carbs are the same as a 38/38. but the SUs flow better then a fixed venturi carb. I wouldn't go more then a set of DCOE webbers. I have a pattern that pierce manifolds sent me and you'll have to make your own manifold with a tube to each barrel, they aren't spaced right to bolt right to the engine.

Any updates on the SU conversion?

I've been gone a while

I was thinking of the 38 but in a dual configuration.
it would mount something like this, minus the float bowl facing the valve cover.

^^that looks hot mike...

yea I got the air cleaners built,I'm going to try and get the manifold welded up tomorrow. it's just a matter of money right now. it's gonna cost over 200 to have the roller throttle shafts put in by z therapy. plus the cost of the rebuild kits. I think for now I'm going to work on getting everything fitted then save up the money and have the two carbs swapped out by them on exchange. it'll be cheaper in the long run and they are experts on these carbs. I could do it my self but they do everything,even use replated linkages,their patented roller throttle shafts,match the two carbs perfectly to each other etc. I won't lose any money because the core on these is over 200 bucks,and I still got the manifold out of the deal. when everything is fitted I send these two carbs off for an exchange,get two ones back in perfect condition and bolt them on. makes a lot of sense to me. these are from a 72 datsun 510 sss 1600 by the way,the way SU carbs work the same carb will work for a number of different engines and displacments with little tuning needed. The person I talked to at Z therapy said they run 2200 cc datsun race motors with this same carb setup all the time with no problems. if I want to go up a little all I have to do is change the metering rod and jet. the carbs are the same as a 38/38 downdraft,but they flow a lot more air due to their design.
here is the air cleaner thread,I still have to taper the velocity stacks inside of the air cleaner. never mind,I put both threads on the post above

[lostforawhile]

here are the two main links to the carb project I'm working on,has anyone ever thought of haveing a specific carb project section in R&D? I've seen some neat projects so far and it would be nice to be able to browse through them in one place. us carb guys ae the old schoolers. BWHAHAHAHA!

I was looking around on ebay & seen these two 32/36 carbs on a TR-6. This would be cool on an Accord. (pic might not stay on here for a length of time)

[A20A1]

I saved the image just in case... I'll try to find more TR dual manifolds on google or something.

i'll be building a DCOE manifold sometime soon. i just need a welder and i'm good to go. i have the DCOEs and just about everything i need to tune them. i don't really wanna replace a good working carb, though.

[A20A1]

Use what I'm using

weld it with a simple torch

hey A20A1 that is so hot, you rock with those intakes

There are alot of carbs you CAN use!?

[hondaman1986]

so if i was going to use the holley 5200 on the stock mani could i use a civic to weber adapter plate or what adapter would i use to make it fit?

civic to adapter plate, HUH is right!
Use Redline Weber Honda A20 Accord adapter plate, allows you to use weber style carb on same manifold as factory carb. Adapter kit is around fifty bucks, then you will need to fab a linkage, unless you also buy the Rline Weber linkage kit, then you still have a puzzle to put together cause it is kind of universal.,

[hondaman1986]

well the reson i asked is because im trying to get the parts from my local schucks store rather tha order the because i have some friends that work there and will give me a discount on anything i buy so can someone post a pic of our carbs base plate with mesurements so i can see what is close to ours i have the tools to make it fit so i just need it close in order to work.


this is from a civic( i think it was a cvcc engine) is it close to our cars plates?



and this is a 20r from a toyota

[A20A1]

I don't see Shucks carring a weber kit... Jegs might. Nopi might.

I bought the plate for $50... pretty cheap.

We have a REDLINE store here that sells weber parts and also stocks parts much like a NAPA does.

You may have to special order it but special order the correct part... the civic doesn't look like a match to me.

[hondaman1986]

no shucks doesnt carry redline but they carry trans-dapt

ive also heard that a rochester adapter will fit our cars is it true or was i getting pulled along?

[A20A1]

What? nothing but the kit fits without modification... only the weber adapter plate that is made for the accord will fit without mods.

You can try different adapters or even weld and redrill and tap the manifold to use a weber and not need any adapter plates...
even then you still need a 0.50 - 0.75" spacer to run the weber/holley... or the throttle linkage will rub against the manifold and thats why you can't run the weber/holley directly on the manifold.
it requires work on your part.


The adapter is high enough so that the linkages don't hit the manifold... it's $50 for two plates.

Rochester?

I'm putting a Q-Jet on my manifold... but look at my manifold.







this is the stock manifold with weber adapter
