4.11 gears into EA?

Is this even possible? I'm looking into as a modification to make driving with lifted rig/larger tires a bit easier... when I do the lift, that is. What I'd like to do is take the 4.11 ring gears out of a legacy or whatever else has them in it, and put them on the ea81 diffs. Will they fit? Or would I have to have ring gears custom built? If it would work it'd be awesome. Anyone try this? or know bolt patterns/gear sizes? I'd imagine the pinion would have to be swapped as well. Thanks in advance, just gathering info atm.

if you can swap 4.11's, why not just go all out and get some 4.44's??? thats what i'd do....... even better crawl ratio....

 

I believe that the 4.11 gears are much more easily adapted to the EA tranny then the 4.44 as IIRC the 4.44 only came in autos

Just a guess, but id be thinking:

 

1. Front housings, input shaft and primary reduction gearsfrom a d/r EA82 gearbox.

2. Shafts from an EA82 fulltime 4wd box, because these, having the centre diff, have the same general layout/hollow second shaft as a EJ20 box.

3. R&P from the EJ20 box, and use whichever centre diff and housing fits best. For onroad the EJ one with a viscous coupling, offroad the open/lockable EA82 fulltime one.

I suspect the major problem in this might be matching up the centre diff or housings if they use different splines/bearing sizes etc.

A 4.11 Viscous rear diff would bolt in nicely and youre done.

 

Here in NZ there is a legacy which has a carbed EJ18 engine and a fulltime 4wd box with push-button lockable centre diff, just like the late EA82s. And a 4.44 final drive. The contents of one of these boxes *might* be able to be retrofitted to an EA82 box, as another option. Then the 4.44 viscous LSD from an Auto turbo one would be perfect to complete the package. Hell, just swap the whole EJ engine as well!

i'd be willing to pay a grand for the 4.444 gears. i think it would make it all worth it.... i seem to remember someone saying something about having 4.444 gears in the d/r ea tranny would allow you to run at least 31's and it would be like driving on the original 13's gear wise..... that sounds good to me....

More like 29's or 30's I worked out all the ratio's once and I think it worked out to 28.78" with 4.44's would be like stock 175/80/13's. Yeah a grand's not too much to pay for close to stock gearing IMO I jjust hope it works and I haven't gone through all the work for nothin.

Alright now this is talking....subscribe for sure. Project Cheap really needs this. We gotta nail down if it's possible and how hard it is. I'm almosted tempted to save some cash for an extra d/r tranny and an EJ tranny just to see what's up. I would be willing to save up a G or so to get my gearing back.
