Anoter ea81 5spd d/r swap thread!!

I swear I had some thread or isn't there a write-up on this somewhere?.. and I can't for the life of me find it. I need some clarifications on some things. I know you guys have numbers for me. I just got my tranny all mounted up, thanks Jerry. Here's what I want clarified:

Driveshaft length. I know I can use the two piece, but I don't want to weld crap up. I also think a one piece is a better idea. Do I need the part that goes into the transmission from the ea82 driveshaft.. or will the one from the ea81 driveshaft work as well? I need to have it lengthened "x" amount of inches? So it will be a total of "x" amount of inches when complete? (Tubing? Overall? Etc.)

4wd selector length. I got the shifter stuff all hooked up good.. there was actually a bolt there on my 84 brat for the shifter bushing to bolt up to. No drilling required. It is a little tight in the rubber.. but seems to be fine. It looks like I am going to use the stock ea81 4wd selector so I need to lengthen it, I know which part. How many inches? Thanks.

Axle Length. Because I am using a 5spd from a turbo I have (25?) spline axles. I believe all ea82 axles are a couple inches longer anyway? I have the axles in now and it seems to be pushing it a little off camber? Should I have the custom "ea81 length" axles made up?

Steering Arm Length. Manual steering.. I don't think they are long enough to be properly aligned. How can I remedy this? Cut and weld? Add an inch on each side?

Clutch. From what I gather I want to use my ea81 4wd flywheel and pressure plate? And then the clutch and throwout bearing from the ea82t? Is it possible to buy these parts individually from the stealership? (I usually just buy the autozone clutch kit...) I may have everything I need.. but it wouldn't hurt to have a new pp, t/o bearing, and clutch disc.

Wiring. I'm sure I'll figure it out.. but does the plug that's on the 5spd plug into the plug that was for the 4spd.. or does it need editing?

Starter. Ea81 or Ea82?

 

P.S. I am using the 4-wheel disc brakes and rear LSD from the turbo as well. In your face nay sayers!:Flame:

 

THANKS EVERYONE!

Thanks.. it's a good checklist.. but I am looking for more specific answers.

 

Good write up here by TheSubaruJunkie.. I didn't need any brake info.. I was just bragging! :clap: Thanks for the bump!

You should put the 25 spline inner DOJ cups from the turbo car on your EA81 shafts, well that's how I know it's done.

 

The EA81 propshaft needs to be about 20cm longer, I don't know the exact measurement though, sorry.

 

I would recommend getting a complete ea82 clutch kit. Your box should be setup for the EA82 stlye thrust bearing and the ea82's friction disc has a bigger spline vs ea81. The presure plate from the EA82 kit should bolt to your EA81 flywheel, granted it is a 225mm clutch.

For the stock Clutch set up you need the EA81 flywheel and the EA81 pressure plate and the EA82 clutch disc. I got all the parts seperate from autozone for about 150$. Use the Ea82 starter, but remember to use a lock washer in between the starter and the transmission, the ea82 starter is like 90 thousands bigger. Which wiring? I think most of it bolts in, I had to cut the speedo cable, the plastic threaded part, a little when putting it to the 5speed, the ea81 is a little longer. But everything else worked fine if I remember. Hope this helps.

Okay, Having the wheels on there and trying to fully bolt down the suspension I am definately going to need the shorter ea81 shafts with the ea82t DOJs. Hopefully MWE is still offering board member discounts, because I want to have my XT6 axles done too. I think I will bring the driveshafts down to a local driveshaft shop and explain to them what I am doing and just have them make me one that is the same overall length as the two piece shaft. I'm sure the clutch stuff will go alright.. hopefully I can get away with just buying a throwout bearing. The wiring I'm refering to is a few different wires on some sensors on the tranny that come into one white plug.. I just haven't checked if it plugs into the old one from the 4spd or what have you.

 

Jerry told me how much I needed to lengthen the 4wd selector but I totally spaced it. I can cut and weld at my cousins house.. so I just need to know how many inces or cm to add there.

 

On another note.. since I am using suspension components from a turbo hatch I would be able to bolt up the rear sway bar.. however the rear wheel width is a few inches more narrow now. Is it okay to cut and weld on sway bars.. or should I just leave it off since it didn't really have that sway bar to begin with? Same thing on the front.. but there is no body points to bolt the bushings to. Any thoughts? No need for extra anti-sway, huh?

I think that covers it :clap:
