It's pretty common, when I was still wrenching for a living at a Chrysler dealer we would still get them in from time to time. One of the techs used to scoop up those jobs quickly. He had it down to 20 minutes. Overall, the 2.2 Turbo is a stout engine that takes surprising amounts of boost well. We had a Shelby Charger that was up around 18 psi. No idea on the HP number, but it was fun.
