Run a search for AWD 240z, and you will get some interesting hits. There is a link to a black skyline drivetrain s30 that is awd that I've posted before (although I wasn't the originator, I too found it while searching). There is not much more info than a scan of a Japanese magazine article, but it has some pics, and proves it has been done. I'm sorry to hear about your father though. As for a build plan, I'm about to start one of those myself. I've got a deal with my wife where if I put together a list of things I want for the car, I can just check them off for presents and so forth, but it has to be on the list so there aren't any surprises. I'm just trying to make a decision on drivetrain, and whether I need a g-nose or not...
