I added a turbo to my HPX diesel with great results. With the fuel turned up a bit and the turbo producing 5-7 psi, I would estimated HP to be in the 35-37 range. It sure makes it a lot more fun to drive. Dare I say it gives it a "sporty feel". I considered producing kits but I have been unable to find the time to do so. Here is a link to youtube. https://www.youtube.com/watch?v=m4nb1HSk6rc

I do have a second turbo sitting on the shelf if anyone is interested.
