tranny search (formerly $#!@ i can't afford this)

["Edgar Allen Joe" <jab86@cornell.edu>]

thanks to all of those who have responded - anybody who would like to
continue to do so regarding alternates/parts they would like to sell me,
please continue to do so, as this problem is far from solved.  here is what
i have found so far:

one person has offered me a stock unit, but it is a little out of my price
range - thanks again to that person.  another has advised me to look into a
box from an 85-87 4kq, which has the vacuum actuated locking diffs instead
of a torsen.  this is an interesting possibility, but i do not know how i
could attractively put the locking switch in my interior (i know it may
sound like a small thing, but i spend a lot of time in my interior).  i am
also concerned with disabling my ABS when i lock the center diff - i don't
want to forget.

here is what i think may be the frontrunner in my search - i would
appreciate any input on it.
i found a tranny from a 92 s4 for sale that i can afford.  i have some hope
that i can use it, as the S4 was a 5-cyl like my 80q, right? would i be able
to fit that unit into my 1990 80q?   furthermore, might that even be an
upgrade?  is the S4 tranny geared better for sport driving?

thanks again for helping me out with this - i really appreciate it!
