I don't think anyone said it's bad. It just seems to be a fair amount of work for not much perceived benefit in power. If you're after better mileage then it could be a good fit. If you're after a money savings, you'll probably have to drive it a good long time to make up for the cost of the transplant. Durability? Better than a 2.25p but again, you'll have to drive it for a very long time to make up for the difference. Cool factor? Absolutely. Good, bad or indifferent...it all depends on what YOU want out of it. Your truck, if you want a 200DI then go for it!
