Convert my 1985' Grand national motor to an 86'-87'

[James velez]

I am currently having my 1985 GN motor rebuilt from the ground up. I was entertaining the idea of updating it to an 86'-87' motor because of the better setup. (ie. Turbo placement, intercooler) Although involved, obviously now would be the best time to do this. What parts do I need exactly? So far I'm aware that the exhaust manifold, ecu, wiring harness, and intake manifold are different. What else? And can I use the stock 85' turbo in the new location?
