Does or had anyone know or done a full diesel swap from a 3.0 to a cummins engine? I live in a place where there a lot of guys who own trucks and smog people. And figured if it was possible to be able to fully switch this luxury car into a diesel smogger. Basically intent is to be stuck at a stop light next to a guy who sits there rev'ing his engine next to me and just mind blow him by the sound of the engine in this type of jaguar.
