Holy hell that's cool.

back to life!

 

 

 

Now, has anyone ever done this or heard of this?

 

 

Twin webers on a dual carb EA-81.

 

 

 

I found another one at a wrecking yard today with a subaru adapter!

 

So either i am going to slap this weber on the motor currently in my wagon, or i am going to have a dual weber EA-81.

 

 

MUWAHAHAHAHAHAHA!!

 

There are a couple of issues you will most likely run into trying this. One i think the carbs are going to be too close together if you are using the traditional 32/36. The other is tuning. You are going to basically have to start from scratch as the tuning for a single weber is going to be completely off if you do duals on the same motor. Finding the right jets and getting all the transitions right is going to be a pain. If you can get them to bolt down next to eachother then your halfway there. I would recommend getting a wideband honestly and tune it using that since there will be a lot more to mess with with two webers.

Why not just Overhaul those dual Hitachi's thats what I plan with My Dual carb EA81.

These are a full mechanical setup no vacuum operated secondary and already factory jetted so why would you change them.

Yes with a US spec Polution Vac secondary Hitachi or Worse then a Weber conversion makes sense,however with these carbs being a specific performance model made to suit the Engine it doesn't strike me as smart to throw them away.

When you fit this setup on a normal EA81 then the cam and porting differences will require some jetting changes.

People out here in Australia have had both the Dual carb setup on a standard EA81 and unfortunately for them A dual Carb engine without the Manifold and carbs.

Consensus is that the performance improvement from either option is similar so when you have both together it is a major upgrade,after all whether it is the 108HP version or the Homologation special 120 HP version both well and truly exceed the Turbo EA81 let alone a stocker or the USDM model.

I need a throttle linkage to hook the carbs together. My engine didnt come with one. So either i need to jimmy something or i need to find a supplier of EA-81 dual carb parts (LOL)

Aircraft guys. EAA is it? http://www.eaa.org/

 

Looks like you need to join to find Classifieds. Good luck.

 

I'm sure there's a couple other places you might do well hunting at.

I was thinking about pulling the throttles off of regular carbs and rigging a cable system. might work, or there might not be enough room...

Factory linkage was a bar so that the cable would go to one side and open both carbs the same amount at the same time. Dual cables? I dont think that will work but prove me wrong!

The factory cable had a bar at the end I have one I'll try to get pics for you If I can find It It may be a few days (in texas right now on a job) I'll post them when I get back home

Not sure if they'll be helpful, but these are the best pictures I have of the stock throttle and choke setup. I can't take new ones because I just sent my engine off to storage.
