i saw a CRX that was converted to AWD using the CRV tranny. he did a good job on it, and didnt have to do TOO much custom work(but there was quite a bit). he mated the CRV tranny to a b18c/t setup. i dont really know much more about it but i think the owner was happy with the result. the only problem i remember about it was that he had a lot of ground clearnce issues with the rear subframe he used. it was really low. im sure someone on here has the link to it, i dont remmeber it.
