I'm working on gathering parts for a carbed zc/d16a1 swap and i'm looking for my best options for a carburetor. from what i've read it seems as though it would be a weber 38 DGES. Prices new are around $350 and i'm sure i could find one cheaper and rebuild it if I could find one off of an older car at a pick n pull or something, or even off of car-part.com. Did it go under any other names? (as the 32/36 also went under a Holley model but was the same carb)
Thanks

Where did you hear that the 38 DGES was best, just out of curiousity?

i don't remember exactly where i read it but i'll try to dig it up.
and i mean best downdraft. i'm aware the sidedrafts are superior.
do you believe that a 32/36 would be better?
*edit* found it...

The 32/36 is a nice improvement over stock(10-12% I figure) but the next step up would be a 38 and it's supposed to be significant increases in power.

According to the Haynes Weber manual, they came stock on 6-cyl Ford Granada's and Capri's in Europe. I don't think there were any North American cars that came stock with it, but I'm not completely sure. You may get lucky and find one on a car that replaced it's stock one. They're popular upgrades for Jeeps, the BMW 2002, and some import trucks like Datsun/Nissan and Toyota.
I bought my 38 new for my Datsun 720 but I ended up selling that, so in it went to my Civic. You'll have to fab your own mounting plate or modify the 32/36 mounting plate to make it fit properly. I'm still trying to work all the kinks out of it. You'll definately have to rejet it or you'll risk running too rich.

thanks for the advice
i looked around on ebay a bit and saw that people are using them for the bmw 2002's, and i believe that it said it came in a some mid-late 80's toyota pickups and celicas. need to check into that.

The only thing I see in the Haynes book is Ford Consul/Grenada, Granada 3000, and Capri 3000. I assume these must be Euro cars.
Is that carb syncronous or progressive?

I think the 34 DMTR would be better or the 36 DCNF. The DCNF is a DCOE sitting upright, for the most part. Not to say the 38 DGES wouldn't be good. They just seem to be set up on V6s always. Weber still makes them. They're called "Outlaw" carbs. Well, post your results. You may be on to something for all I know.

My early carb research indicated the 38 DGES was the next "stage" when choosing a downdraft carb.
I had read a weber line breakdown that promised 12-15% more power and "noteable" improvements in fuel economy with a 32/36 DGV over stock carbs. Now, they were talking about old Datsuns so take that claim with a grain of salt.
They also noted even more power was available with a 38 DGES (something like 15-20%) but it would sacrifice significant fuel economy over stock.
That loss of mpg, coupled with the added complexity of a synchronous anything carb setup, steered me toward the 32/36 DGEV.

i see. seems like the 32/36 would be the more 'balanced' choice, so i guess i'll be shopping around for one of them.

Yeah...that was my thinking.
I dug up one of the articles I read comparing the 32/36 and the 38:
http://www.webercarb...t_choice_32.htm
If you go with the 32/36, I'll give you the ballpark jet sizes for the ZC/D16a1. That way you can avoid starting from scratch. My wagon isn't done by any means but I think the carb is reasonably tuned.

I shouldn't be hard to find a 32/36. They're on Ebay all the time.
