Unfortunately this is a nearly impossible question to answer without know what it needs. If it is just a cylinder head and one piston it could be around $2,000.00 but with over 150,000 miles once you tear it down, I am sure you would find more. Which is normally why most people don't do this anymore unless it is their own vehicle and you don't have to pay labor.
Sorry I can't give a clear answer but without looking at the parts when it is torn apart there is just no way to know.
Plus just doing a quick search online showed many options on rebuilt engines for less then $2,500.00. Clearly this doesn't include installation but if it comes with a warranty, this is what I would be looking at doing.
