I didn't mean to give that example to say that if a K26 was put on a 3B it would explode (obviously =) , just "my experience" in doing so.  I think we just got a bad rebuild and the turbine came apart, though racing at 6k feet up a hill in the summer can't be good for turbo's anyway.  We just had to eat it and move on to the next turbo, oh well.  A K26 would be a cheap option for a upgrade turbo though much better turbos are out there.
