It would be impossible to say without knowing how much time is on the engine, and the idivudual timed componants as well as any damage history or exceedence history in the recorder. The last 207E I was involved with cost $330,000 thru Pratt and Whitney. That engine got new compressor turbine and power turbine discs.
There is a company in Phoenix that might be able to assist you either in the overhaul or overseeing the overhaul and making sure you don't buy too many parts that are not required to be replaced. Search for Phoenix Engine Services in Mesa Arizona and ask to talk to Doug Whitmarsh.
