I am looking for a back up sled for my family and friends to ride. It may even be for me and I would use my stock sled for the back up. I have noticed several turbo sleds for around 8,000.00. I know a good turbo set up is 7,000.00 in parts alone. Then there is stock sleds with low miles for that price. Can a used turbo with 2-3000 miles be trusted? Some say new top end and some have recent video's that the sled runs great. Why do these devalue so much? I know aftermarket stuff can devalue a sled, been sledding for years, but why take such a hit? Why not return it to stock and get money for the turbo kit? If I bought a used turbo sled for around 8,000.00 and it has good compression, what are the most expensive issue's I could have if the sled decide's to start breaking down. On pump gas turbo's, how much messing around do you do on each ride with the boondockers fuel controller if any is there?
