you know i had almost that same idea only i was thinking to put the drivetrain from the old AWD civic wagons into my 90 Crx Si. the think that is stopping me is that im not exactly sure if that would work for one, and i've never seen how the setup is under the car, (like the drive shaft placement). also i was wondering is the transmission on those is all time AWD or just in low gear? i hope someone out there can help me. it would be much appreciated. thanks!
