EA-82 Carb recommendations?

[romcat]

Was reading about Weber adaptations for the EA-81. I have a 86 Dual Range 4WD Wagon, w/electric mirrors etc, I think it's a "GL". I believe it's a EA-82, so what would be the smart "carbing" to do here. Also how does the airflow through the intake and ports of the Ea-82 compare to the "81"?

 

Thanks,

Gareth

weber 32/36 or holley makes similar

from what I have heard, the FWD Carbs are the ones with most of the solenoids and all the crap. They run ultra rich and then the solenoids and the computer tunes that down. The 4WD ones i hear aren't hooked up that way, and it's for easier tuning.

 

I would say either rebuild your current carb, sell it to me, or buy a weber kit for your car.

 

As for manifolds, the EA82 manifold is slightly larger inside for airflow, and the carb mount is a larger opening. ( better for the weber )

 

Manifolds will swap, but require some work!

Your 86 most likely has a hitachi carb.

Get a weber carb for it...

 

If you keep the Hitachi, theres a few things you can do. Someone in here had a guide to

removing the emissions stuff. I have it on my other computer so I'll pm it to you sometime this week..

i would like to see this list, for the emissions stuff. i just installed one tonite, and i plugged every hole, except for the fuel in, and the vac advance.

 

i would also like to see how to make it a mechanical secondary.

after screwing with a weber for a year, im back on the stock hitachi wagon.

Don't know on the list, but the mechanical secondaries mod is in the USRM, or was. Thinking it was SubaruJunkie (Brian) that did it. May be on his site.

K heres the list... I havent done it yet.. Another board member (I wish I could remember the name) sent this to me:

 

 

Ok, to start I can?t find any pics of an EA 82 to show you, and I sold my GL wagon in the spring, so I don?t have the car to use as a reference. I also tend to makeup names for things when I don?t know what they are called, but I?ll try and be as descriptive as possible.

Things you?ll need:

1 gallon anti-freeze

1 set intake gaskets

Deluxe multi pack of vacuum plugs

2 3in x 3in x1/8 in pieces of aluminum

1 3in 10mm length of allthread

1 can or tube of RTV

3 pennies

1 air box top from the J.Y.

1 plastic elbow plumbing fitting from the hardware store

1 12pack of Old Style or some other cheap beer

Black Sabbath Volume 4 (you can sub with any early Sabbath album)

 

Now I?m assuming that the car has a Hitachi carb and is non AC. Also you may want to remove the alternator to give you more room.

Crank up the Sabbath!

Jack the car up, block the wheels, etc, etc. Take off the air box and disconnect all the lines and hoses, chuck that but keep the top part and wing nuts.

Next disconnect the fuel lines, master cylinder vac line, the heat selector vac line, the chock/vent solenoid wire connecter from the carb, upper radiator hose, throttle cable, along with the temp gauge and oil gauge wires (and anything else that connects to the intake).

Unplug all of the wires going to the little emission solenoids.

 

Now you can start tearing all the lines off, remove all the 3 million brackets and vac lines from the hard lines on and around the intake, dump the vapor canister vac booster, all that crap!

 

Ok, from under the car at the exhaust manifold you?ll see a hard line coming off right above the exhaust pipe on each side, I call these the sideburns, I?m not sure what they are really called but it doesn?t matter because they?re history! Unbolt them but save the bolts and the gaskets (I think there?s gaskets, I can?t remember), you?ll need them later.

 

Now pull the intake manifold, and remove all of the hard lines, I think it?s like two or three bolts.

 

Pull the rest of the sideburns out from above, and whatever is left. This is a good time to plug the heads clean the block, I like to use oven cleaner.

 

Crack your first beer.

 

Once you?ve got everything cleaned up and the hard lines off of the intake, bolt that bad boy back on with the new gaskets.

 

Using the aluminum plates, fab up cover plates for the holes where the sideburns came off, and bolt them on.

 

Crack second beer.

 

Reconnect the master cylinder vac line, and fuel lines. Connect the vacuum advance on the distributor to any vac port on the manifold. Do the same with the heat selector vac line.

 

Run a hose from the driver side rocker cover to the PCV.

 

Plug all of the ports on the carb except the vent solenoid valve. On my EA 81?s I run the large port on the back of the carb to the manifold. I don?t think I did it on the EA 82, but you might try it.

 

Plug the EGR valve on the back of the intake. I?ve also removed the EGR on my and made a cover plate for it. Seemed to work well.

 

Reconnect the radiator hose, gauge wires, choke wires, and throttle cable.

 

Start it up! If it starts and won?t idle or idles ruff, check that all the manifold ports are plugged. If it idles but stutters or stalls when you whack the throttle, check the ports on the carb. Pump the brakes to make sure your getting vacuum boost. Turn on the heater to be sure you have vacuum to the selector. Check for exhaust leaks at the sideburn caps. Readjust the idle and fuel mixture accordingly. Top off the coolant.

 

Crack your third beer.

 

For the air cleaner, or air box as I like to call it, take the lid from the J.Y. and cut a

2 3/8in diameter hole in the center (the outer diameter of the mouth of the carb). Using the RTV glue a penny over the hole on the right side (looking at it from above and reading SUBARU left to right). Hog out the left hole and install the elbow fitting, this will allow you to run a hose from the bottom of your air cleaner to the passenger side rocker cover. This will be the bottom plate of the air box.

On the other lid, glue pennies over the left and right holes, leaving to center one open. Remove the center bolt from the carb, and replace with the allthread, you might need to put a lock nut on it to hold it down on the carb. Place the bottom plate on the carb, connect a hose from the elbow piece to the pass side rocker cover, put on stock air cleaner, place lid on top, and using Subaru factory wing nut, tighten into place.

 

 

Thats all I can remember, but I'm sure I'm missing some thing!

Hope this helps ( and makes sense!)

for the air cleaner part. i just found out that the plastic elbow from an mpfi DOES fit on to the hitachis. ea81 and ea82. i had to cut down the rubber fitting that connects the carb to the elbow, because the hood wouldnt close. then i routed the hose to a cone k&n.

i call it the ghetto snorkel.

 

why would you need to keep the carb vent open? i thought that only dealt with the carbon canister, and not the functioning of the carb.
