Default rx7 trans in an impreza

i know that this is kinda crazy, but i heard someone say something about using a rx7 transmission in an impreza the other day and it got me thinking, how possible would it be? i was thinking that you could get a bellhousing adapter made and custom driveshaft+ axles for whatever rear diff you used

the non turbos use the same size clutch (225mm) disc as subarus so i would think that you could use the subaru pressure plate and relase bearing with the 7' disc. the cross member could be sussed out, but what about shifter linkage? the rx7 just has the shifter mounted directly in the top of the trans where as the subaru uses a linkage. i would think that if you mounted the 7's tranny the shifter would be behind the opening on the subaru. i dont really know how to deal with that (besides making the shifter shaft shorter and moving the whole thing forward).

does anyone know if this has beed done or have any ideas on it?

why on earth would you want to!
if you want near industructable RWD form a scoob (well as close as n a buget!) use the 6 speed sti with the spiders out of the mid diff, get the midd diff welded and the run it to a r200 (from a nissan 300zx) youll need custom mounts and shafts

I might be putting a W58 Toyota transmission in to my Legacy. If that goes well, I may upgrade to the virtually indesrtuctable Mazda Turbo II trans.

I'd think the shifter will be too far forward, considering the spot at which Subaru motors sit in the engine bay (far forward). If the RX shifter sat too far forward, I'd just move the motor back and modify the mounts - it wouldn't need to be kept forward for axles or anything.

BTW, I already have an R200 differential in my car. It's kinda clunky, but they're tough as hell.

The distance of bellhousing to shifter on the W is really similar to that of the EJ trans and they're 50 bucks at the junkyard (from Mk III Supra). If I do it, it probably wont be for another month or so, or when my RWD converted trans starts biting it, but rest assured I'll keep everyone updated.

Any info on how well these work?
I'm in Sacramento, if anyone has a Bare Block laying around, We can meet up and see how well the T2(mazda turbo II) trans fits.
Because if it fits, I'll be selling my whole FXT RWD trans(welded center Diff)
