EJ AWD into EA 4wd gearbox

if its not 3.7 and the single range is just unbolt the pinion shaft from the inside of the bottem gearset and swap it with the matching front diff

Its actually a bit more involved as you need to get the pinion height (in relation to the CW) right .

Alpine yes most L's have the shorter 0.87 5th but RX Turbo 5MT's are 0.78 and have 3.7 ratio diffs .

Subaru screwed up badly with the speedo cable drive because you can only get at its nylon gear from inside the case . They should have used Nissans system where the whole assembly can be removed externally .

Also Gee9 (K9 ?

) tells me that the early Lib boxes have a three bolt front bearing cover and these are the ones that L casings fit , don't know if gen 2 are like this .

At the wrecker I actually gave them a "white lie" it was 5 speed RWD instead of 4WD (with transfer case) that is how i got it cheap...

Yeah can't wait to open the box up, I'm hoping it has 3.7:1 ratio diff!

Just cracked the EJ Dual Range box up... it is 3.7:1 ratio diff!!!!!!
Pictures will come soon in new EA to EJ thread.. - keep watching in gearbox section...

EDIT:
Its now located: showthread.php?t=13511

I just happen to be reading this at 5:15am, dunno why, you'd think I'd be out driving my new lease on life Project Cheap Grief - yee haa

I like to read the idea of 'just' fitting up an AWD EJ box [don't care for ratio selection or maybe not even dual range] to my L with EA82T just for AWD. Have I missed something? Someone mentioned an adaptor between the EA82 and EJ AWD box but not read any more on it. One is needed ain't it? but no one makes one ?
What happens here? and the clutching ?

back to sleep zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

Nah you won't need an adaptor plate, bec the EJ box is longer than L series box i think its EA box is 16mm shorter? You will need an adaptor plate if you're going to use EJ engine with EA gearbox.

As you do from time to time

Ok, I started this thread a long time ago with the idea of having AWD in my L cos I don't really like front wheel drive... My plan was to see if I could shove the EJ AWD gear into an EA L series gearbox casing - the short answer is YES. This eliminates the need for an adaptor plate (EJ and EA bolting patterns are slightly different) and will allow me to use standard clutch setup etc.

The gearbox will be longer as AP has already mentioned - the rear casing on the gearbox is interchangeable between the EA and EJ main gearbox casings. So you'll need a shorter propshaft - or if you happen to find a single range L series the first section of driveshaft should bolt up perfect I believe.

As for the adaptor plate - you can grab an EJ gearbox and use an adaptor plate to mate it to the EA motor, you just need to by the same adaptor plate used for EJ motor conversions and use it the otherway around. I dunno what happens to the clutch/flywheel on this occasion, probabily use the EJ one I'd reckon.

OR if its an EJ gearbox to EA motor without swapping gearbox casings...

Am I getting conflicting info from two reliable sources here (last two posts) ?

I guess the considerations need be - is the word 'adaptor' correct for differing bolt patterns, or 'spacer' to correct for housing a clutch - for EA engine to mate with EJ AWD gearbox.

It seems that for EJ engine to EA series engines there is need to use a 'spacer'

So bolt pattern is different then ?

Has anyone done this EJ AWD box to EA81 or EA82

tailshaft is last consideration

this thinking out loud is good

have an idea

i have an EA82 engine bell housing loose somewhere

the guy I bought Cheap Grief off has an EJ20 powered Brumby with the pull clutch style RS Lib AWD manual box rear handbraked Porsche discs. The poor thing is just sitting there with its steel Imprezza rims and big front brakes - engine is out , expensive clutch not bought and ran out of rego three years ago now and will need serious engineer report to register again.

i guess I just need to see for meself if the Lib box fits up to said spare bell housing !!

I can tell you now it won't! The two top bolts are in a different spot on the EJ, the two lower bolts line up as per the EA series boxes... This is why EJ engines to EA gearboxes need the adaptor plate - same goes for EA engines to EJ gearboxes!

I tried to correct AP without offence but it seems the message didn't get through. I think we're talking about the same thing though (with the same message in mind) but it got lost in the translation...

Go and have a look at your mates EJ motor with the EA bell housing. If you have the a manual EA DR casing you could do the opposite of my plan - put the EJ AWD into the EA casing - removing the need for an adaptor plate

(I keep saying this cos in Vic you need an engineer's cert for an adaptor plate - something I want to avoid atm).

another diplomat Bennie, I like it !

I thought the bellhousing of the lib box looked bigger !!

I do just happen to have the dissembled EA82 five speed dual range box, so when i get time I will look through more posts, bother a few people and find an EJ AWD box to also pull apart and see if I can get what you are also trying thinking.

Would be nice if enterprising dudes with above talent could sell good converted box eh ?

Those little springs and balls that just drop out of nowhere worry me !

LOL That what my wife said, its something i enjoy and have access to these machinery items and I could get boxes from wreckers do them up and sell... I wouldnt bother with EA boxes, but I'll play with EJ boxes because its easy....

Gee's got a tame Subie gearbox specialist that does these sorts of conversions all the time , contact Gee .

NOTED in my little purple note book.

Look at me, not even thrown out my old 3speed 4WD auto box and its torque converter and crap and i am asking about another box idea !!

Nothing wrong with that
