Engine swaps?
 

I was just curious, not that I have enough money to do this, but. . .Can you swap a P5 engine with that of the Mazda Millenia S? And if so, would it be possible to have a manual transmission? I was just wondering. I mean, are there any engine swaps you could do? Because I've seen the old 929 motors on ebay for really cheap as well.
