I was wanting to pull a little more horsepower out of the little engine. The oxidizer was replaced a few years ago along with the turbo for free by a local dealer. I don't like the idea of emission equipment on a diesel especially those that may have reliability issues as well.From what I understand, you have to re-do the entire system (if it's possible). I cannot say for certain, however my opinion is that it probably wouldn't be worth the time/money put into it. You may run into problems down the road with non-compatable items, etc. It would probably cost over $1,000 to replace all the necessary parts and labor costs.
