The first question would be how does the mechanic know that they're the 
same exact engine? Appearance wise, I'm sure that they're quite identical. 
However, based upon this same observation, even the PRV in the Volvo 260 
appears to be the same as well, which we all know, they are not.

The online listing of PRV variants isn't totally complete, so the key factors of 
engine version, and the compression ratios are missing. Both are indeed 
listed as having a displacement of 2.8 litres. However, the list does say that 
the Peugoet 505 motor is fueled by LH-Jetronic, and we know that the 
DeLorean utilizes K-Jetronic. So we know that this makes them totally 
different in the sense that the 505 version at least doesn't have the heads 
drilled to accomodate the Fuel Injectors, and their supports.

Is there anything worth salvaging/adapting off of the 505 motors? Who knows. 
If you're really interested, the only way would be to pick up a service manual 
of some sort to check out the details such as the compression ratio and 
whatnot. Otherwise, the comparison guide does show that the motor puts out 
slightly more BHP than the DeLorean. But then again, even DMCH has 
shown that with a little coaxing, the PRV is able to pump out qute a bit more 
power. So technicly, it could be the exact same motor, but with only a slightly 
better exhaust system.

If it were me, I'd just get a nice, low-milage Eagle Premier motor (early '88-'90 
version w/electical distrib.), swap the lower crankcase & oil pan, drill the 
heads to install supports, for the Fuel Injectors, and then just swap intake, and 
fuel injection systems on over. Instant increase in displacement and BHP 
that's even-fire, with minimal modifications (the hardest parts would be the 
drilling, and the installation/removal of the motor). Then just slap on a nice 
free-flow exhaust, and you'll be ready to go. No EFI systems to screw with 
installing, buying, tuning, or even building for that matter. Just tune the K-Jet, 
system and you'd be all set.
