Of course, with ford's recent examples, I doubt it is. I it probably just like the other ecoboost engines, high pressure, fake numbers, and a crap job of engineering.

But would the turbo last as long as the engine? Even with the turbo resulting in better gas mileage, if the turbo gave out before the engine did you'd still have to deal with that. Would the amount saved by the increased fuel economy for the reasons you mentioned more than cover dealing with the turbo having given out before the engine? If it did, would that be worth the hassle? Some might feel it would be. I don't feel that way.
