I am trying to determine which transmission would be needed to put more than 600whp to the ground in an FC? I have seen the T5 kit, the 2JZ 6 speed kit, heard rumor of a T56. At what point does the NA s4/5 trans fail? At what point does the T2 trans fail? Thanks for the help and the info.

 

i blow up a n/a trans while auto crossing at 250whp , i now run 583 whp with a t2 trans , so far handling the beating , im having little problems shifting at high rpm "8k" so im trying to find a solution.
