Uprating gearbox

What do you uprate in the gearbox when you go for more power in your engine say upto 400bhp?

Would it just be the bearings
and obviously an uprated clutch kit?

Expect ££££'s

PPG kit for 5 speed is over £2000 alone, dunno what 6 speed is.

clutch - £800 for good AP Racing organic heavily uprated ( see Xtreme Scoobies ) or over £1200 for twin paddle, so I was quoted.
