3.1/3.8 Engine Swap in 89 GPse

Anybody out there ever swaped a 3.8 supercharged engine into an 89 Gpse 3.1. I have a totaled 97 GP with a 3.8 SC it only has about 60k on it and I want to put it in my 89 GP. What would have to be modified? I figure it would bolt in using its wiring harness and computer, but what about exhaust and such.:banghead:

my friend has a 96 gp se swapped, i can put you in touch with him if you'd like.. also www.l67swap.com (http://www.l67swap.com) will answer all your questions
