st205 in a st? Options

[quicknstyle]

ok, now that there are a few more st205 3sgte's going into gt celicas, it seems to be that they are a lot easier swap than the st185, correct me if im wrong, but according to what ive been searching, wiring, the main headache in the swaps, seems to be a breeze, but i havent seen anything involving the st. what i want to know is are there any more of a difference between in swapping that 3s into the gt or st, other than tranny, because i already plan on changing that out? mounts are still usable correct? and mainly wiring, if i plan on keeping ac and all that. if anyone could shed some light on that for me that would be great!
