Over the last fifteen years I have been accumulating a collection of parts to build a reasonable clone of a '72 ST. One of the things that I acquired was an original engine from a '73 RS. It's from a car in the 12xx serial number range and is complete, apart from being fitted with a non-original muffler. At the time I acquired it, it was installed in another 911, not the original RS. The guy that owned it was parting out the car and I bought the engine from him. He had no history on the car, as he wasn't really a Porsche guy and I think he had just stumbled into this car by accident. It was running and driving but I didn't make any further attempts to determine the engine's condition, other than to check a few numbers to ensure that the correct major components were all still there. I had always planned to disassemble the motor and rebuild it for the project, as I wanted a few things changed to be more in line with what the factory actually put into an ST. Plus, I wanted a little more power… At any rate, the engine was removed from the car by a local shop and put into a wooden crate for storage, where it has been for the last decade, or so.
At this point I may not finish the project and I am thinking of selling the various parts. I'm not sure what the engine would be worth, in today's market. Obviously, it would be worth a fair bit to the owner of the car that originally housed it, although I suspect that the car no longer exists. I've never found it listed on any of the registries. I see people asking what I think is silly money for some of the parts (like an injection pump), although I have no intention of parting it out. I think that it should stay intact.
Any opinions as to what this engine might be worth? Have there been any recent comparable sales, that I have missed? It's one thing to determine the valus of a part, or two, as individual parts come up for sale often. Complete RS engines, on the other hand, as rare as hen's teeth, so how does one determine a value on something like this? I actually did do a search before posting and the only other, similar thread that I could find was about 6 years ago.
Many thanks,
