Hey buddy, that PRV v6 that came in the Deloren is a pretty sweet motor. I had one in a Volvo wagon and loved it. They suffered problems with the cam oiling if the oil was not changed often enough and other minor problems but it is a very torquey motor and will accept some modifications without stress.

I had about 130K, with no problems, on mine when my Mrs. pulled out in front of a very large american car and got the left front bent over to the right. I did follow a rigorous oil change regimen though of every 2K iirc, but the oil thirty years ago was not nearly as good as what we have now.

The bottom end is built like a Cosworth Indy racing motor with a full girdle on the main bearing caps. It was the basis of the ground shaking Renault F1 Turbo motors which produced well over 1000 hp in qualifying trim.

Putting something heavy in there will ruin the nice balance of your car which has the engine out back like a Porche 911, right?

There has to be plenty of them available in the salvage yards. Putting in a non original motor will involve a tremendous amount of work and money. I would find the latest version of it and get a good one and go for it.

Its an oddfire v6 and when you push it it gives off a growly moan that is just very very nice to listen to.
