Zenith 32 NDIX

Vanapplebomb · Posted: Thu Dec 01, 2016 7:10 pm Post subject: Re: Zenith 32 NDIX

I really wish EMPI would reproduce the NDIX line of carbs and manifolds to match. Say what you want about EMPI, but they make some darn good reproduction carbs. The 32 NDIX could be popular in singles and duals on mild T1 engines. The 36 NDIX would be good for hotter T1 engines and mild T4 engines.

They had such a good floatbowl to emulsion tube relationship. They were practically at the center of the float bowl! It gave them good fuel control at higher angles, hard cornering, and rough ground.

With the price of old 32 NDIX carbs going up a lot, and 36 NDIX carbs pretty much unubtainium in the states, I think reproducing them might have promise providing manifolds were also made available.

Yeah, Just saw the Empi ad on the back of Hot VW Magazine January 2017 issue,
Looks like they have 5 carburetors:

HPMX 40 /44
EPC 34
EPC 48 / 51
Progressive EPC / 36F
38EGAS

Did the aftermarket ever make any VW manifolds for the 36 NDIX, or was that limited to the 32? Bolt pattern and bore spacing was the same, just larger throttle bores.

The isolated runner manifolds might not work, But I bet the plenum style's made probably would work, but I have only used 32NDIX with Cast Plenum style.

Good question, you'd think the diagram below would help, seems to me they are.... unfortunately they don't use the same terminology in the diagram as they do in the table. For a 1776, according to the table you'd want 50s. The last column is for a dual set-up.

May want to post in the thread below also to keep all Zenith info in one place.

Hi all,

I am trying to find out if the throttle plate (cast) in the attached thread is broken.

I'm interested in purchasing, but am weary of the plate on this carb.

Any help is appreciated.

Thanks,

K

I have 2 Zenith carbs, and they both have that slot. I have run them as singles, on both a plenum style manifold, and on an isolated style manifold, on my 1914. Worked fine on both. As I understand it, on a smaller motor, the isolated manifold works better.

Joemama: Much appreciated!

Does anyone know where to get rebuild kits for these carbs? I'm resurrecting an old hot rod motor that hasn't seen the light of day for over 35 years with dual 32NDIXs.
Thanks!

joemama · Posted: Tue Jul 28, 2020 11:12 am Post subject: Re: Zenith 32 NDIX

Not hard to find. You can find them on Ebay, as well as most vw/offroad shops. Be aware that most rebuild kits do not include the accelerator pump, also available on Ebay. There are 2 accel pumps available, one short, one long. I think the long is for single carb applications, but dont remember for sure. Measure your old one, and match that maybe.

I honestly never thought of looking on ebay, figured they were probably too obscure. Thanks for the tip!
