Wait, was your engine originally turbocharged? Are you looking for a replacement turbo or are you looking to add a turbo to a normally aspirated engine?
If the latter, then good shape is important, but also the actual measured compression of your engine and the amount of boost pressure you intend must be calculated if you want more than just a few blazing accelerations before critical meltdown occurs.
How many miles does your engine have on it? If your seats and rings have any weakness at this point, it won't take too much boost to turn those weaknesses into problems.
As far as finding a turbo kit for it, I'm sure you can find something with a diligent Internet search.
