I'll address your excellent forensic lab distributor post after I chase my
mailbox thru a bit...
WRT the below is much simpler. The 91 200 trans has a torsen center, I'm
presuming you to think that's a good thing. I don't, most folks go the 'other'
way, and a 4.11 locker is available for the 5ktq. However, the rear torsen
from the v8 is indeed a 4.11 and is a bolt in to the 5ktq rear end. That part
of your project is good mod IMO. Take the whole rear end down complete from
the 91, that gives you the vented rear brakes that bolt on to your 87tq, and the
better rear upper spring perches that also bolt onto your 87, then bolt the
91 subframe into your 91

I recently purchased a 91 200tq tranny to put in my 87 5kcstq. I believe
my current diffs are 3.89:1 ratio. The 91 200 tq has a 4.11:1 ratio, so
I'm going to have to swap in a new rear diff as well. Does the V8
quattro from that same era have the 4.11 ratio? If so, is the diff the
same size so that it would swap in to my sub frame? I'd really like the
Torsen rear diff from that if possible.
Also available to me is a 91 200tq rear sub frame. Any idea how much
these usually cost? I know it won't bolt in to my 87, but I could use
the diff, and then overhaul the subframe to put under my 91 tq.
Thanks for any insights you may have--
Oh yes....for the mandatory distributor content....I purchased a new
dist for my 91 from Rod at The Parts Connection about 2 months ago. Cost
was ~$280 and it came with a narrow tip rotor. FYI, Scott @ SJM has
these for about $270 as well....but I already ordered mine before I
found that out. Both Rod and Scott are always great to deal with though.
