Carb EJ How to

Recommended Posts

This is a conversation I had a while ago....

I was the second to attempt it in the states.I made it run. I ended up having transmission issues and did not drive it.
It is an early Escort, or EXP Disty. taken apart and had the shaft ground down to fit the end of an EJ cam.

I took a Cam out of an engine, took the shaft out of the disty(bought new in the end, used a junkyard model to figure out the fit.So I actually ground down like 4 I think.Pretty sure I spent about 200 bucks getting it right.
then I "fit " them together.
Then I started test fitting on a head. As seen here



You also have to modify the disty advance because of it wanting to hit the frame rail.(in an EA81)

Unless you get the non advance model like shown.

The electronics was super easy. I went to Ford and got a simple wiring harness diagram.

The intake I bought from a plane builder in Canada. An older company named RAF used to produce them.
I would just make one now. Scott casted a bolt on piece for an existing EJ intake. He said it worked fine, but I don't remembering see it run. So I don't know. I am sure he has a video on Youtube.


cheers, maybe more to come....Just gotta remember it..

Thanks -I was looking at some right angle distys with similar drives -
(like here: http://www.cardone.c...d=302492&p=rock)

...are the key ways in the cam ends different -is that what you were grinding on the distributor?


Sent 20 November 2013 - 06:44 PM

yeah, it is because of the keyway difference that it needs to be fitted. But it is very minor . It should be done with a hand file , or a mill.
This one.
AUTOLINE Part # D4069 from Rock auto.
It is the easiest one to modify/locate used parts for. I did buy a brand new harness from the stealer ship but, It was not color coded. Just black and white. I had a color coded one I pulled from the junkyard once too. It is kind a straight forward really...

And actually I just realized that the Disty in the photo is like a later one I think. Maybe because it has the non adjustable advance. Is that an oxy moron? lol
The one I ended up using had a vacuum unit that I modified to use with a wing nut.

I have been looking for pics , but I have some random naming systems.LOL

If the hood would clear it I'd be all over it -Doesn't seem that complicated if you can get the intake to mix right.

I'd probly just cut a hole in the stock intake -I'd like to see the carb intake next to the fi one for comparison. How'd they fit that?

Actually what this is about right now is farmyard type power plants for low tech types.

I just really liked carbs. And got told it was  not possible. lol

The RAF intake was made from the runners up.



Here is my setup.I almost forgot about this.

Hey sorry I've been busy with other stuff. Thanks alot for all that! Do you know where to find the manifold, or would it just be easier to fab something up? Happy New Year!

I would build my own if I were you.
I bought mine off of a whirlybird website. damaged at that, one of the runners was dented and taken out of air service. Originally it was a 600 dollar piece. But if you can weld aluminum , it would not be that hard.(mine was steel)..
The bottom of the runners is the goocher. As it turns oblong, not circular.



Sent 28 December 2013 - 06:59 AM

Looks like they squished the ends and welded them to a plate, probably doctored them up from the other side?



Sent 28 December 2013 - 11:47 AM

They were not squished together. They were pressed with a custom interior die made the exact same shape.I inquired to the fabricator that built them for RAF. He also said they port matched the head to the runners when they installed them.
Everything was machined and fabricated properly. Definitely not a backyard product.
Not to say it could not be done with some ingenuity in your backyard. :)

Interesting. Maybe not a one-off piece, then a run of them was done, perhaps... I did a search  but only came up with Royal Air Force -lol...kind of would like to see what they were flying with these motors, some kind of ultralight?

Sent 28 December 2013 - 08:42 PM

There was a small run of them done.
The folks I was in touch with were using them on ultra lights, and other small "experimental"(this is actually a classification) aircraft.

To adapt a Disty + Carb on a Subaru EJ engine that originally came EFi is not easy at all. Beside yours, I've seen such setups done in USA by Jerry (Bratsrus) and Scott (Scott in Bellingham).


It is a shame that the Laws in USA about pollution, forced subaru to quit selling Carburated engines in USA too early... the LADM (Latin American Domestic Market) specs, and other worldwide markets received factory Carburated + Disty EJ engines on Legacies (EJ18 and EJ20) up to 1994, and imprezas (EJ15 & EJ16), this is a short video of a factory dual range Legacy that I was about to buy, where you can see the factory Carb'd + Disty EJ20, running:





The Thread with Subaru's part numbers for the two different EJ Distribuitors, details, photos and links to the Cab'd + Disty EJ FSM, is here:

Maybe you find helpful info there.


Kind Regards.

It was less of a question, and more of a HOW TO Jeszek :)A question mark got put into the title by accident. And I could not take it out.

Please keep this post for additions of tech ONLY.

No offense, but this is mainly for the USDM. And Jeszek, I did this before Jerry and Scott. lol

I've got a couple of queries:

where is the factory distributor on an EJ motor fitted? I'm still trying to see where and haven't found any pics.


Which Escort was the dizzy taken from? Cos the US Escorts are called different things in different parts of the world. Some of the FWD ones are called a Laser in Aus.


I see that the dizzy was fitted to the RHS camshaft, with is good for LHD models, any reason known why it couldn't be fitted to the LHS camshaft for RHD models? Thinking about clearance for the brakes & steering.

Not only the Ford Escort distributor could work, also the Early Mitsubishi Lancer Distributor, and the one from a Ford Laser / Mazda 323.
