The Vortex turbos have had issues lately and it mostly seams to be with the latest few shipments, an idea of how the qc was lacking was when they "eqt" had a rebuilt turbo they were sending me returned to them enroute cause they had found out that the manufacture may have mislabeled xl and standard turbos so some people were getting the wrong ones. I know that don't speak of the failures bit it does speak of qc, luckily eqt found out about it before long. I have seen a number of the turbos having issues with the journal bearings failing, a number of them not making or holding boost. Tpc has been out for some time and there are a lot of there turbos out in the wild, and tpc also doesn't make turbos for just this platform, they make turbos for just about everything.
