going from 84 brat ea81 dr trans to 85 wagon dr trans, need to know which clutch disk to use with the ea81 flywheel and pressure plate

 

Is there a benefit of using the ea82 turbo clutch disk?

Flywheel and presure plate from the engine - clutch disk and throwout bearing from the trans.

is a TURBO disk better than a carb disk?

Don't know, I put a LUK clutch disk in my Brat when I switched to the 5sp.

That's certainly true providing you originally had the 8-7/8" diameter clutch disk. I can't tell you if the turbo clutch would work. Get a good quality clutch (LUK, Sachs, original Subaru) and you should be okay. In my conversion, I went with changing the flywheel to the EA82 version so all the parts are from an EA82. Only a slight modification needed to the casting to have the EA82 flywheel clear.

Being a 84 Brat, I assumed it had the 8 7/8" clutch.

A valid assumption; but in 20 years people put weird things into their cars when they should know better (sometimes they don't because their mechanic doesn't tell them). I learned this the hard way when I found an engine from a 2WD hatch in our '84 4WD wagon and found I ordered the wrong clutch for my car.

Yeah - I've seen a LOT of early subaru's with replacement engines. The dead giveaway is finding a hydro lifter engine in a car that obviously couldn't have come with one stock.

 

When installing the 5 speed, it's prefereable in my opinion to use the complete EA82 package for an off-roader (heavier flywheel = more torque), and the EA81 or the XT-6 setup for a street rig. The XT-6 setup is nice for it's stronger pressure plate.

 

It's very simple - you use the clutch disc that fits the splines on the tranny. The rest can be pretty much whatever you want, but using the EA82 stuff (or XT-6 stuff) has the advantage that the PP fingers match the release bearing correctly. The EA81 PP fingers are not the correct size for the EA82 release bearing. Also - don't forget to transfer the timing marks to the EA82 flywheel.

all ea82 4wd 5spds, turbo and non, full time and part time, use the same clutch disc
