tensil strength has never been and never will be the issue, a mild steel manifold can support your turbo just fine, if it was the issue everyone would be running around with tungsten manifolds, but that would most likely crack in 15 minutes, because tungsten may have the highest tensil strength of any metal but its also the most brittle metal
its just not cut and dry stronger is better, if your are building a frame that supports weight and never changes temp thats one thing, but being able to expand and contract without cracking is a WAY different ball game
Forgive me if I don't take your word for it. My "Friend" has been doing fabrication for a while now. To say that he has no understanding of that he has no understanding of it is a load of horse crap. He dose't run of theroy he runs of experice because he knows what works and what dosen't. How long have you been doing it? Longer I hope to say he dosen't know what he is talkin about.
