Default Converting FWD L to AWD

Does anyone know if this is doable? If so what is required to do this.

Thanks for any help any of you can give.

It is doable. You need the rear AWD suspension, axles, differential, crossmember, and the AWD gas tank. There may be more parts that I'm forgetting as well...

its a real PITA , im undergoin this now actually. However my difference in my project : Im swapping in parts to accept AWD components before i go all the way to AWD , meaning im not swapping in the tranny , diff, or drive shafts yet. off the top of my head you need :

AWD gas TAnk (sending unit and pump as well )
Lateral Links,
Trailing Arms, (correct name ? )
AWD Hubs
AWD knuckles
the rear subframe ( might be the crossmember not sure )

then of course rear brakes , you can get AWD drums or DIsk,

I did the whole thing. 95' 2WD L to a '98 STi. Used a 99 wiring harness and dash, 2000 front end, STI IV driveline.

I hope you are planning on using some sort of modified axles to hold the hub/wheel bearings together. If you don't use anything, your bearings will fall out on a hard turn which will equal major suck.

I have a friend that is turbocharging his 93 impreza. Him and I both know that when he does this his tranny will go. He thinks that he can take an AWD tranny of a newer impreza out put it in and still keep the front wheel drive. Am I correct to assume that when you take an AWD tranny out you have to convert everything to AWD?

im the friend

i know the tranny will hold the power, its just the clutch im worried about. what he is talking about with a replacement tranny is an AWD tranny with no driveshaft or anything, just front axles. im not looking for info cause im not worried about anything yet and its still really early, i just thought i would clear some things up.

Find either a wrecked 91-94 awd legacy (perferably a turbo model) or a 93-01 impreza and get it for parts. There are a lot of little things that if you miss will cost you an arm and a leg.
If you are seriously considering this swap i have the rear end out of a 93 turbo sedan for sale including everything but the tranny and rear diff. The brakes would be from a 96 legacy and not the 93 turbo ones.

Pretty much everything. The two cars are built on the same unibody so they share the same parts. The only thing you can't use is the sway bar as it's a little different due to the larger spare wheel well.

so if I can use legacy AWD that include drive shalf and everything?!?! does that also mean when I buy suspenstion stuff I can still use impreza springs and what nots? also can I still use the rear brakes from a legacy to do the converison? oh and one more thing would an exhaust system made for an AWD work for a FWD as far as clearing everything or do I need the AWD

Yeah, i'm pretty sure the driveshaft and all that is the right length. I know for sure the splines line up on the transmission out and the differential 4 bolt pattren is pretty standard.
My stuff won't come with a differential or the driveshaft as i might be needing them for my conversion. I might be able to get a 3.9 open diff if you could use it. But most of this stuff is pretty much available in any junk yard for a good price.

Good question and one i never really thought too much about. I know most people add a set of springs and struts when doing this but that's manly just because they are there.
I would think most of it would be the same. Maybe different spring rates/strut valve proportioning but i would think the suspension layout is the same.
