Your best bet is to make sure you do your research on the manufacturer providing the parts/kit and the shop doing the work and find one that is legit and willing to stand behind their work. I doubt you're going to find a warranty that will cover a bad tune or shop incompetence for aftermarket turbo installs or even random failure of parts. Some insurance might cover aftermarket body kits, but they won't cover the labor to make sure the panels are all fitted properly or custom body work.
