4sp to 5sp confirm

[ihscout54]

Ok im going to the junk yard this weekend, i was givin alot of info but im still not too clear on what im looking for in a five speed, if i swap to a newer 5 (85-91?)speed (which was recomended by members of this board) will my clutch parts be from the 5 speed or do i use the stock?, will i need to change my drive shaft length?

what if i find an older 5 speed (81-84?) is this not a good tranny?

i have an '82 brat gl

what exact car am i looking to pull from, there are no brats or hatchbacks with useable trannys here so will a sedan or wagon work?

1. They didn't make 4WD 5 speeds before 85, and they were never installed in the EA81 series cars. You need a 4WD D/R transmission from an 85-89 wagon or sedan only (the boxy, EA82 cars). The D/R 5 speed was discontinuted after 89.

 

2. You have two options for the clutch. Use the 225mm EA82 clutch disc (with the round spring section - the square spring version won't fit the EA81 flywheel), and release bearing (from the 5 speed donor), or use the complete EA82 clutch setup, and swap the EA82 flywheel for your's. I would recommend using the enitre setup, as being an '82 Brat you have the older 200mm clutch and will have to replace the flywheel anyway - might as well use the EA82 flywheel. You may need to add a single 3/8" washer under the starter bolts to clear the EA82 flywheel.

 

3. You will need to use the driveline from the EA82 vehicle. It's already the right length, but you will have to fabricate mounts for the center carrier bearing as it's a two peice affair. Alternatively you could have a driveline shop build you a new driveline, but that's always more expensive. Also, the two peice is less exposed under the car so less likely to get hit on some obsticle. Subaru went to the two-peice for this very reason. The longer you go, the more driveline you have sticking out under the car. It's an option if you can't weld, but the EA82 shaft works great if you can or have access to someone that can.

 

4. You will need to fabricate some on the transmission cross-member. You will see when you get the 4 speed out and set them side-by-side. If you do it right, you can get away without beating on the transmission tunnel, but you have to be VERY accurate with your new mounts, and the transmission will need to be angled backwards *very* slightly to accomplish this. Or you could just buy the excelent kit from Bratsrus1 (Jerry). His kit is AWESOME, and makes the install much easier.

 

5. You will use the 5 speed linkage, so grab that. You will need to weld in 1" of rod into the 4WD shifter rod from the 4 speed, and it will work great on the 5 speed. Just remember to shove the 5 speed linkage all the way over to the drivers side when you tighten it's rear mounting nut, or it will interfere with the 4WD rod.

I used all the EA82 parts, but needed shims for my flywheel bolts. You will need a flywheel from an 83+ EA81 (8 7/8" diameter clutch) and the friction disc and pressure plate from an EA82.

 

will i need to change my drive shaft length?

Yes. You can use the two peice shaft off an EA82 (This requires welding the carrier bearing to the underside of the car). Or you can have your stock one lengthened, but to how long, I don't recall. This is the route I went with on my wagon.

 

 

what if i find an older 5 speed (81-84?) is this not a good tranny?

The only five speed during that time was 2WD.

The tranny you want was only avalible in EA82 cars, so only look for those.
