I am thinking about building a dune buggy like car on a subaru drive line for the awd. But I'd like to make it rear engine. Does anyone have any information on reversing a Subaru drive line, any year? I know I could run it upside down, but would that be a problem for the transmission oil? I would use a differnt engine on a conversion plate right side up. I was hoping I could just run the "front" differential upside down, and then flip the "rear" (in the transmission) differntial so the transmission can run ride side up. Any info on this method?
