How much power will a gearbox take

Hi i have a 2001 ce lancer coupe
Ive been thinking of doing some track days, i have done a lot of track days with a civic that i built with a friend, but i had to sell my half as i moved interstate.

Im thinking of upgrading the brakes with ts tr magna twin pots and fitting some coil overs.

I have been doing some reading about engine swaps and turbo but i cant find much on how much power the 4g93 gearbox will take.

So the question is how much power will a stock 4g93 gearbox take?

If i did an 4g63t convertion but keep it fwd, what gearbox would i use and how much power will it take?
 
I’ve been running my 4g93t for 4 years, same box.
Was on 110kw up until 12 months ago. Now lots more.

I’ve punished that box harder than a hooker in Kings cross with 3 years of skid pan motorkhana. Replaced the clutch once the whole time. Still seems as reliable as ever.
 
63t swap requires use of the standard evo box and transfer with some internal modifications..... probably won't ever brake the stock box without awd, some serious engine or *poo* driving but you'll smash the diff in no time and when you upgrade that you'll destroy CV's and shafts lol
 
Cool so you have to use evo drive shafts and then evo knukles and then wheels and brakes too
 
For circuit racing the second hand info i have is about 200kw will start breaking 4th. I'm guessing the heat being generated in the longer gear is enough to kill it.

for drags mine was making about 230kw when i started breaking things. but it wasn't the power but the brutal launches with slicks that ended up snapping a few drive/half shafts.

i installed the fto box because it has bigger shafts but no idea if it would be any stronger with the actual gears.
it does have shorter ratios so might help it a bit by not giving it so long to build heat in that gear...
 
Does anyone know whether using the transfer case makes the driveshafts to be equal length or is one still shorter than the other?

They're close enough to being equal leingth... Haven't measured the difference but it's not enough to cause any torque steer on mine
