OK, so I want to use a 5-speed with 4.111 final drive and AWD on my EA81 Wagon (why 4.111 I hear you ask, well I'm going to run a high revving 100 hp EA71 in it - one with multi-point fuel injection but that's another story).

 

Parts:

EJ transmission TY752VF2AA (single range 5MT with viscous center diff) out of a 92 Legacy

EA transmission out of a 85-86 XT Turbo (with on-demand 4WD)

 

Idea:

Use EJ gears in EA 5MT housing and use EJ transfer case with AWD coupling. Jerry (Bratsrus) is modifying an EJ cross member and shift linkage so it will fit the EA81 body.

 

First milestone:

I disassembled the EJ transmission a few weeks ago (with the priceless help of my 4-year-old son) and only found time to take the EA transmission apart last weekend. As I have stored the EJ internals I decided to do a first trial fit the other way around (I heard one bearing would not fit) so I put the EA shafts in the EJ housing. And guess what? All four bearings fit like a charm. Assuming it will also work the other way around I expect I will only have to adust clearances when assembling the EA transmission with the EJ gears.

 

Here's a picture of the EA shafts in the EJ housing.

 

Now I have to clean the EA housing and find time to assembly and adjust the transmission. Then hopefully Jerry has finished the modification of cross member and linkage so I can finally drive my restored car!

how you gona bolt a ea 71  to that trans ?

Using two bolts and two nuts

 

But I guess you are referring to the bellhousing. Well, the EA71 that I'm going to use is a 1986-1993 version so with the starter motor at the same position as the EA82.

Might want to stick some 23 spline stubs into the front diff while it's all apart.  That way you can use stock axles.

 

Also, I do hope Jerry knows you are using the AWD tailsection.  His "regular" kit is for the Part Time 4wd EA82 5spds, which are shorter and mount a bit different.

 

 

 

Make sure you get the opening in the C-clip on the big bearing in place.

 

Make sure the big bearing on the lower shaft the bolt holes are oriented correct.

 

Make sure the pinion and front upper shaft bearing seat on there pins properly.

Thank you for the pointers.

 

I have sent Jerry an AWD EJ transfer case, mount, crossmember and shifter mechanism. He has bolted it up to an EA82 housing is going from there.

 

Regarding axles, I have a 5-lug conversion done and am already running modified EJ front driveshafts.

Pic of motor ? whould like to see

Great.

 

Sounds like you got this one tackled pretty well.

I hope so...

This is an awesome conversion, I'm onto my second one now - also with 4.111 ratio.  But I've gone the other way, into a dual range EJ casing (Oz spec!) to make fitting the EJ engine in much easier.

You'll love the AWD!

Cheers

I've always had AWD in my Legacies and I don't like the part-time 4WD system

 

A friend has all the genuine Subaru tools and fixtures to adjust clearances so I'll probably do to assembly with him at his place early next month.
