turbo coupes came with t-3's the 5spd's had .63a/r housings and the autos have smaller ones i think .46?. you would definitely need two of those for a big block, that may not even be enough. you are going to have a helluva time fitting them in your engine bay, i dont think you will have enough room to flip the headers so you will need "turbo headers" that are already made.
if you had a 5.0 in the car i would say you could do it for $500 but with a big block in it i think you will have a hard time doing it for cheap.
i would buy a kit thats already made with a t-76 or pt-88.
OR JUST SPRAY IT
