dave valiant Posted October 3, 2003 Share Posted October 3, 2003 I own an 84 Brat Turbo that unfortunately has an automatic trans. It cant get out of its own way until the turbo spools up. Ive never modified a Subie before and wondered if anyone could help me with suggestions about what 4 or 5 speed can be used. I had an 84 GL Wagon that was a whole lot better off road than my single range auto Brat. Would that 4 speed work behind the turbo motor.any help would be greatly appreciated because here in the Black Hills area there doesnt seem to be anyone who knows this stuff.

TheSubaruJunkie Posted October 3, 2003 Share Posted October 3, 2003 Yeah, that 4spd will work behind the turbo. You'll have to install the peddle assembly which is the hardest part. Other than that, its pretty much a straight swap. You can put a 5spd 4WD tranny in there as well, but its alittle more work. -Brian Link to comment Share on other sites More sharing options...
dave valiant Posted October 3, 2003 Author Share Posted October 3, 2003 Sorry I forgot to ask will the drive shaft from the auto work with the manual. Are the splines the same on the input shafts. Will i need a longer or shorter driveshaft. Are there any good bolt ons for a little better performance.Thanks Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted October 3, 2003 Share Posted October 3, 2003 Being a turbo, there's always room for performance upgrades. Not sure if the Auto driveline will work, i think the auto is longer than the manual. if you get the driveline that came with the tranny, it should work fine. The wheelbase on a Brat and Wagon are the same. -Brian Link to comment Share on other sites More sharing options...
Kernzie Posted October 3, 2003 Share Posted October 3, 2003 I put a 4sp in my 84 Turgowagon and you have to use the rear-end from the standard and the driveshaft. Not sure it the Brat would be any different. Hooking up 'back-up' lights is a problem in this application as the switch for the auto is different than the standard and it is a pain to try and rig something up.

MilesFox Posted October 3, 2003 Share Posted October 3, 2003 i just typed all this up and lost it, so here goes again..... a 4spd will fit the same, as long as you carry over the driveshaft and rear diff, and crossmember, and its mounting bolts. there are 2 suspension bolts that will be taken out, and the longer ones that hold the crossmember on will replace them. you can use a 5spd, but it may not exactly clear the trans tunnel. you will also have to cleverly mount the 4wd shifter, as it is different in design. jerry (bratsrus10 can offer his services to make an install kit, you sent him the parts and he will modify them, it will get the ea81 4wd lever to fit stock on the ea82 tranny. you may be able to stack wahers on the crossmember bolts to drop it down for the trans to clear, as General Disorder dod to fit a 4spd in a 2wd. I put a 5spd in a turbo 84 wagon, but with a 3 inch lift. when using the 5spd, you will need the flywheel/clutch, 2pc driveshaft(or lengthen your existing), and the rear diff that has the 3.90 gear. i cant remember if the ea82 flywheel bolts fit on the ea81 turbo, but on a normal ea81, you use the skinnier ea81 flywheel bolts on the ea82 flywheel's larger holes. the flywheel will center itself the way it fits against the crank. you will not have to modify your engine bellhousing, being a turbo. the crossmenber from the 5spd(ea82) will fit the same as one from the 4spd. a 4 and 5 spd will have the same axle spline as the turbo's AT it has been done a number of ways, so if you run into a problem, just refer to the collective expertise on the board! be specific in questions, because one might have done it a different way than another, and one of us will have the answer to your specific methid. good luck!
