I know of two xb owners that have run 8-9psi daily for over two years with no problems, with some internals upgraded. Yeah, it isn't the greatest motor in the world but its not that bad if you build the motor right. Unfortunately, most don't.

And some turbos have more lag than others, no one turbo design is the same as another. Do some research and you'll find the one for you.
