There are no definative answers to this question.

It all comes down to how hard you are going to drive it, and how often you will tolerate rebuilding it.

correct Tom, but its a properly thought out question none the less,
torque ,rather than the old hp question.

Vroom, i have been putting lots of torque through my rear box which is an A series ,not A plus and it cracked on the centre web sometime within the two year spell between teardown, more than likely sometime last year as i started upping the power, but every other component was in perfect condition.
