turbo 3.1 swap into 94 cutlass surpeme 3100

[94 cutlass 3.1 turbo]

I've got a low mileage '94 cutlass supreme and a no title '90 mclaren grand prix turbo. I want to put the turbo 3.1 in my cutlass and swap out the 3100, I noticed the computers look completely different but transmission, motor mounts, etc. are the same, does anybody know if I can do this swap. I know the turbo setup would fit my 3100 but I'd rather use the better internals of the turbo 3.1? Any help would be greatly appreciated!
