Ok, I can give you the information about the turbo specifications for Z31's.
The 1984 turbo Z31's came with an oil lubricated T3. The 1985 to 1987 turbo Z31's came with an oil and water-cooled T3. The 1988 and 1989 Z31 Turbo's came with an oil and water-cooled T25.
The turbo's maximum efficient boost is between 14 and 16PSI for the T3's. The T25's I am not sure about. As far as the bolt-up capability of the Z31 T3 turbo's, I have not been able to get my hands on a Z31 T3 again (I was stupid and gave mine away) to try it out. If anybody knows for sure whether it's a bolt on for 20 or 25's, I would like to know. I would assume for sure the oil and water lines will need to be altered and possibly new ones made, and possibly the housing rotated, but I'm just guessing.
Anyway, hope that helps.
