I have a 1987 Callaway TT Corvette, picked it up cheap....but turbos are toasted I believe. I do not know much about turbos....I work on NA cars mostly. The turbos are IHI RHB52

Looking for other direct bolt on options for the car or a rebuild kit.

Any thoughts would be appreciated

if the turbines on the turbo are still good then just remove them and have them rebuilt. rebuilding the ones you have will be your best bet. trying to put different brand turbos in its place may require modifications to the oil feed, oil drain, exhaust and/or turbo piping.
