the cost of an uprated box is not alot of money really if people only think about it, its such a shame people see the engine as the heart of the car, then all the hard earned goes on the motor, the people whinge because the gearbox shits it self
for the region of £2500 buys you a decent used quaife big tooth box, some people will spend that on a fookin turbo ffs, as for the shift being bad, thats just a design to aid drivability i,e reduce noise and nvh
if you want decent shift quality you need one of these
as for the box ability to handle power , i would say it takes a midges over 330 ft/lb in a quick boost time to shred 3rd gear, which is not surprising when you see its profile
