will the box be OK?

[bangers]

i've done some more googling. the rb20det stock put out 214bhp and i'm hoping for @300bhp so i think the box should be ok. but as bax said its down to torque. anyone else have any ideas?

My brother has a cefiro with RB20det and std man box. Its got 180kw at the wheels(dyno) and he thrashes it and the box just keeeps going... in saying that any box will give up if you give it death all day...
