as one of the few others that have contiplated this AWD idea.. i have a few insights provided to me from another that has thought of doing it also..

basically we can or should easily be able to use/swap the rear suspension/axles/transfer case and such from a 2g gsx/tsi-awd.. from there we look for a tranny.. and here are a few.. possibly the caravan awd.. another is the new liberty 2.4liter engine version, and also.. the evo. basically we're looking for a tranny that is located on the same side engine bay as ours does currently, and one that drives an awd/rwd platform..

from there we will have to find a front transfer case and possibly make a custom drive shaft to the rear or may get lucky with the use of the dsm awd driveshaft, but a must will be at least front custom axles. then you will have to rig up all the proper sensors, cables, and such, and then we will have awd 420a's

now one thing that has been brought to my attention is that of clearance for the driveshaft, but i believe most of that can be accomplished with using of gsx/tsi-awd parts.. and we may have to cut up some stuff if needs be, such as near the trunk for space for the transfercase under the crossmember (the crossmember is higher on the awd dsm and they dont have as deep of a trunk as we do.

and dont forget you will have to probably redo the exhaust piping from at least downpipe back, might even get lucky and use premade piping made for the gsx/tsi-awd.

just get ready for some spending of some mad cash and down time!
