KT88 always love your posts. It doesn’t matter what you call it, or where it happens.
A private individual in Germany posts on the Porsche forum a certain way to rebuild a 935 motor ( I used to own several) and he talks about many different improvements and he does this in his garage at home, but he really knows his stuff and he talks about his next project that he is going to do build a motor that will yield 850 hp (635 Kw) at 1.5 bar with parts 1/3 the cost a regular motor. So I PM and ask, hey, can I have you build one for me. Sure he says, I need X for parts. I send him X for parts and I will build it. It’s still half of what would cost from the name builders that have the full shops, etc.
Months go by, no motor, he stops responding, I find him on another Porsche forum, start talking again, it will be ready September, no motor, November, it’s ready to ship, no motor, January no motor. There is a post on a Porsche Parts trading site and someone posts that he sent the same guy money for a motor, no motor.
What do they call that in Germany?
