Hi guys just wondering how much horsepower a standard turbo II gearbox will handle on a regular basis before giving up the ghost???

yeah and the diff out of the run of the mill hilux only had to endure about 100hp( and a fari bit of off road trouncing) but has survived many a thrashing at the wrong end of 500hp motor.
   So are here many guys out there running big hp turbo II cars with standard box?
