The factory engine fixture is a "p201" tool. There have been two versions that I know have seen. The early one has four arms which was also used by VW.
The later had five arms and looks like it can withstand much more torque. The was an early two arm stand for VW's but I don't think there were ever for porsche's. Not enough steel to holdup the engine.
I personally have not seen a broken/bent fixture, but there are members who have seen it. Do a quick search on "p201 arm" I think there was a thread about cheaper engine stands.
