Porsche's strategy on engines and pricing has been clear for many years, many models.
Face it, they do NOT want to give the aftermarket owner and world any ability to mod their engines and make any money doing it. They have all kinds of ways of doing this and technology has helped them keep this little market to themselves.
BMW has done much the same thing.
If you like to get at an engine and mod it to death, the Porsche route is a road to frustration. Compare that to a Chevy V8. You can go on the Mr. Goodwrench engine site and shop away.
I am not suggesting that Porsche should do this. To their way of thinking, they are doing what is good for them and perhaps their customers.
So, good luck on converting in some sense, a box engine to a 911 engine.
BTW-If you want to give your Porsche parts guy a heart attack, ask him about a engine conversion.
