Yes, it will swap. No, you do not need to change out wires.

i know that the 4eat ecu will work with a 5mt, but i was reading the how to do post, and he said that he was having a broblem with the timing or something like that due to the fact that he was using an 4eat ecu where a 5mt would fix it....

Don't think so...
I have swapped an auto car to 5mt...and it felt identical to a factory 5mt car.

Yes, the turbo ECUs are the same regardless of transmission type.

You have to remember I did my swap when I was normally aspirated. Turbo ECU, as mentioned are the same between transmission types.

in that case, does this mean that if i have a n/a now, and i wanted a turbo ecu, i'd have to get a turbo harness too? or just mod a few wires? i have a 91 n/a and doing a turbo conversion with a smt6 piggyback and running a t3/t4

You just need to swap the positive leads for the crank & cam sensors, and add the pins for the turbo specific sensors. This must be done on top of the wiring issues associated with the 5mt swap.
