Hi all, wondered whether anyone had ever experimented with an exhaust manifold made of welded plate steel? I can buy a manifold flange for around £50 Euro. Also is the manifold bolt pattern different on turbo/non turbo 606? 
Thanks

Seems like that would flow quite differently than a tube manifold. I doubt it would be better.

I believe that the exhaust manifold mounting bolts for the NA and turbo are the same.

You're going to get terrible efficiency with a big open space for the exhaust gases to slow and expand into. But I cringe at rear mounted turbos.


I remember reading a forum about a guy who made a turbo manifold out of actual box section for a Toyota H diesel. So that's been done.
