7mgte Swap

[SilverBullet05]

My Car: 1986.5 7mge 5Speed
So i have recently found a great deal on a 7mgte motor and i really cant pass it up. I found a guy that has a 1991 mkiii with a 7mgte with auto tranny. Basically he said there was somthing wrong cause the motor was acting up and he has no clue what is wrong with it. So he decided that he was going to pull the 7m and do a 350 swap, hints he knows 0 about supras. So that means he is going to pull everything off the car he doesnt need. This is why its such a great deal the car is mostly a donor car for parts, he is keeping the car but he told me i can have everything he doesnt need. I know the motor will drop in the car but what i need to know is what parts do i need off the car? Also can i use the wiring harness and ecu from the 91? If anyone can help me please let me know i would greatly appreciate it if there is anything else i need to know about this swap chime in and give me your thoughts

Thanks Greatly
