1984 swap with 86-87 parts??

[spoolfool]

Hey everybody, im new to the buick world but not new to the turbo world,
I have an 84 GN that i picked up for a great deal with low mileage 55000 to be exact. I want to do a swap from the 86-87 with the intercooler and the goodies.
My question is, the block should be the same right? As far as i know they are the same but i want to make sure before i start rippin it apart. I have a lot of plans for this car and i want to do it right so with the help from you turbo buick fans, i might be able to make this happen....i mean, it WILL happen!
Plans are,
meet Jack Cotton
more fuel, more boost , more power and alllllll the good stuff.
Any recommendations appreciated..
