I would also suspect that the "reversible" nature of the off-the- shelf transmission being used (i.e. front or rear drive selectable by flipping over the ring gear assembly) had something to do with it, I do not believe that the transmission/engine mate-up design was unique to the DeLorean application. In other words, to use this transmission the choice of engines was very limited. There are not very many rear-drive transaxle designs around, seems to me a Porsche design would have been about the only alternative at the time and would have dictated a different kind of engine or some sort of adapter. And probably cost more.
