Default '84 Subaru GL: FWD to 4wd questions-

I'm looking at buying a 2-door '84 Subaru GL, non turbo, fwd right now. It's a low mileage car that just narrowly escaped being scrapped because it wasn't anything special and no one wanted it. I'd like to convert it to 4wd or AWD if I buy it, but I'm wondering exactly what I need and what years/models of Subaru it could come off of. I found an '86 brat parts car locally as well that's a rot box with a blown motor, but it's 4wd.

If I can't use the Brat, what other Subarus could I use for the drivetrain with relative ease? The Brat has a 4-speed manual, while the GL has a 5-speed, and I'd prefer to keep the 5-speed, but I'm guessing I can't make the fwd trans into an 4wd one. Or can I?

I'm seriously curious, I know nothing of Subarus at all yet, so I'm looking forward to some learnage.

Thanks!

yes! you can use brat bits
no! you can't use your fwd transmission

you definitely can. not too difficult either.

need the 4WD gas tank (indent for the rear diff).
need pretty much the entire rear suspension (a few things could be re-used, but it's much simpler just to replace the whole darn thing).
driveshaft
transmission
clutch/flywheel (I believe the 4WD input shaft has more splines/larger clutch disc/stronger pressure plate/different flywheel)
starter
shift linkage

this will all have to be out of a 4WD EA81 ('80-'84 for sedans, wagons, coupes, '81(?)-'88 for hatches and brats). an entire parts car is definitely preferrable


all EA81 4WD trannies are 4-speeds. you could convert to an EA82 (next newest body style) 5MT 4WD, but that requires more modification.



that's a pretty good start, but I'd head over to the USMB @ www.ultimatesubaru.org for more info. lots of writeups on this stuff.
