We have a 2004 Discovery that we love, but the gas mileage is ridiculous. Our Suburban was a hybrid by comparison. I just got a promotion that came with a company car, and was contemplating selling the Rover. Then I started pondering the idea of converting it to diesel. I'm a weekend mechanic at best, in fact, that's giving me too much credit, but I've been maintaining our cars/trucks and my bikes successfully. Jesse James I am not. This would be by far the biggest project I've tackled. Does this sound do-able? Is it going to be so expensive that it's just dumb? I have a lead on a very low mile diesel motor from a Toureg that got written off in Michigan, and I was thinking about using that. What do you guys think about time, cost, probability of success?
