I saw a thread over on vortex that user Maodys (the guy who posts the awesome ring lap videos) had his turbo blow, and several other owners have had their turbos blow as well, and many times requiring the entire engine be replaced. As far as I know, they are all non tuned. I wonder what this says for the long term tuning potential of this car...
