No need to break up the engine-tranny set--use the whole thing (the turbo
tranny is not the same internally as the v-6). Be sure your u-joint is
good, or replace it, and take it a little easy off the line. V-6s are prone
to shearing driveshaft splines, presumably because of their low-end torque.
I suspect that the back of the v-6 will crowd the firewall if you don't
lenghthen the driveshaft, and as I said on the phone, the engine mounts will
probably not line up on the crossmember with the standard driveshaft. The
steering rack (but not the tierods) and crossmember may require switching
from the v6, and I am not clear whether the v6 requires ABS for clearance,
or will clear the mastervac on the wagon. The turbo and v6 driveshaft and
torque tube may look the same, but the v6 ones are longer. The exhaust will
require some fabrication

I am inclined to think that there is some reason PSA did not put the v6 in
the wagon, knowing full well that there was demand for such a vehicle. But
second-guessing french thinking is not rewarding for lesser mortals such as
us, I have learned in the past.
