I very much doubt it would fit. It would also be very expensive. Probably over $15,000 for the engine, wiring harness, engine computer, tranny, and tranny computer.

Anything is possible, it all a matter of money.

You would also have to consider emissions requirements where you live. Depending where you are, converting the car from a gas to diesel would mean it could not be registered or driven on public roads.

A project like that would be difficult even for a 30 year master fabricator and mechanic.
