was just chatting with a friend in the UK who has a late 80s Jag XJ6 and he was thinking about having it converted to a Nissan Diesel powerplant and we had a good laugh until we found a website of a place in the UK that does just that! I was shocked and amazed, I'd never heard of a diesel powered XJ before and was wondering if anyone has done something like this on a car here in the States, maybee a Cummins Diesel powered XJ with a manual gearbox. I think it's a great idea, but I'm sure it would cost a fortune to convert and you could probably buy several hundred gallons of gas for what you'd need to invest in having the only Jag Diesel on the block
