ELLO CAN ANYONE TELL ME WHAT GEARBOX N FROM WHERE WILL TAKE 456FT/LB TORQUE.

 

I'm running 395 lbft through an STi 6 speed but it does not have enough mileage on it to know what it will be like in the long term.

Others have had some success with STi 4 door 5MT boxes.

Dog box? Depends on intended usage.

Toughened up autobox? Level Ten offer some interesting stuff.
