L Series 5 speed into a brumby.

Morrie · Post by **Morrie** » Thu Jul 26, 2012 1:48 am

Just a quick one, i'm upgrading my engine and gearbox in my brumby to an EA82 and 5 speed.

With the gearbox, what tailshaft do i use? and does the L Series tailshaft fit?or is the origianl brumby one the correct length?

Cheers..

Can I be harsh on a newbie and say please use search funktion ?
Quickly. I used a two piece L Series with my 5 speed into Brumby and got up many thousands of kms - no worries. Sell the Brumby one or keep it for another day - I did and was of use in my other Brumby when time came to fix the uni joint

Yes you will need to use the L tail shaft you will also need to do something about the center bearing I drilled out the ones from a L wagon

The EA82 is a tight fit in a brumby you will need a little persuasion to get it in.

The 5 speed is an upgrade. In my opinion the EA82 is not. There's more to go wrong with them. What you'd be better off doing is dropping the EA82 intake manifold onto the EA81 block. It can be a little technical but it'll give you the same performance as the EA82 with less issues (cam belts, oil leaks)

If you do keep the EA81 you have to machine the EA81 flywheel to take the EA82 clutch pressure plate. I can't remember the amount off the top of my head. Do a search on USMB and it'll be there many times over

Thanks for the tailshaft info.

As for the EA82, my options are to rebuild the Ea81, its blowing smoke and using heaps of oil, so rings or at least another head reco. So $200 for head reco, $150 for gasket kit, and maybe rings and a cylinder bore hone, the wallet starts to get a bashing..

Or for a Few hundred dollars i can get hold of a good EA82 a 5 speed and everything else i need.. and i dont have to pull an engine apart or try to mate the Ea81 to the 5 speed, and messing around with clutches etc, i have done this before and decided this time to just bolt the whole lot in and done.. And if i find a good EA82t, it will bolt straight in..

I remember what i have to modify to get it in and working, like the 4wd shifter, the gearbox mounts etc. just forgot about the tailshaft bit..

Thanks again for the Tailshaft help..

And the bit where you have to "massage"/modify the chassis railing to fit the EA82 in without the cam covers rubbing the bodywork. It's basically the same that you would do for the EJ20G to fit it in. From memory the EA82 is the widest engine that subaru have thus far produced, it's not by much but it's enough to "take the title"

Check it out though. I'm sure there are some game members here that ran the EA82 without the end covers to avoid the rail mods - I don't know how often they went through cam belts with this setup though.

forget what Bennie says about EA82 needing chassis rail mods to fit a standard height Brumby or MY. We've been through all this before, Bennie is getting forgtful in his old age. You get about 4mm clearance of the rocker covers to chassis rails

, timing covers not a problem.

I have dropped an EA82 into my Brumby of std height just to prove or disprove fitment. Pulled it out again when curiosity killed

and is going back in one day. LIFTED MY or Brumby is another matter

There a place in Wangaratta Jonno that sells block and tackle bearings in bulk.....

OK so i got a stack of parts today, but got a few questions for you guys that have played with the awd conversions. done heaps of searches on here today and cant find any info.

I picked up an RX turbo 5 speed, tailshaft and diff with the rear driveshafts, was pretty cheap so thought why not, and what i remeber they were a stronger box..

I know the box runs 25 tooth splines for the the front drive shaft inners, so first question is what do the guys do when putting the awd boxes into brumby's with the larger 25 tooth splines? is there inner CV's that work on the standard brumby shafts? or is this going to be a custom build job?

Next question, are the rear inners going to fit or are they larger aswell and need similar mods to fit.. the diff looks like it shouldn't be to hard to fit into the brumby..

Cheers Morrie..

did you get a box from an RX ? Thy were part time 4WD not AWD in most cases - our market anyway, or you got an AWD Vortex 5 speed?
It is just the L Series mpfi, mpfi turbo and RX box and Vortex turbo 4WD think inners that you need to fit to Brumby CV shaft and Brumby outers (me too ) gave up trying to remove the unremovable L inners and will have to buy new 25 spline inners to fit to std Brumby front shafts. Rear diff splines all the same between MY and L variations, I believe

Series one liberty inners (the outer cv hub) with MY inner races and bearings?

this is from somewhere on the board

Yer it's the RX turbo box, the guy i got it off wrecked a RX turbo wagon, obviously an import.. the box has a stack of wiring on it..

I'll do some photo's of my brumby project, so far i've done the 6 stud conversion now running 16 inch alloy rims from a navara and i just finished the interior with a 6 speaker sound system, a 12 inch sub and fully airbrushed dash..

So Toonga you just run the outer casing from the series 1 lib with standard brumby internals? That way i get the 25 spine to the box and works on the brumby axle?

I've bought some driveshafts from a CV guy that does reco's, i have an older one that needs an outer rebuilt so was just going to get him to build one to see if it works.. if i can give him a head start on parts he should be able to build them for me.. I'm not a fan of rebuilding CV's, was to messy..

Yeah I am - I didn't realise/forgot that this was for a standard height brumby

Or if you want to keep your stock brumby front shafts you can use a non MPFI L series gearbox OR if you like to get your hands dirty and learn a bit about your gearbox you can swap the diff output shafts by splitting the gearbox, the stubs are held in by a circlip each.
