They are definitely taxed beyond their limits on big power turbos, and i fully admit that we dont do much with the smaller 2 stroke stuff so they may be holding up better and i just dont see it.

When the entire moveable sheaves are exiting the vehicle, thats a pretty big deal.
Our fix for them is to throw them in the trash on day one.
