If the engine is a 2.4 and ran at some time with CIS then you are probably looking at a 73 1/2 911T.
That is the only 2.4 that had CIS from the factory.
If the engine has been sitting for years there is a good chance that a bad compression reading will not mean the engine is bad. On the other hand a good compression test will only tell you about the rings. A will have cast iron cylinders in some form and cast can rust if there is any moister present. The next problem is that if it sat where there was substantial moister water can separate from the oil and corrode the case around the oil strainer plate.
Lots to think about when buying an unknown quantity.

The engine number on the fan support will tell us what you are looking at.
Good luck
