designing a turbo manifold
 

I am designing a manifold for my dseries engine. I have seen some setups where the 02 snensor was located pre-turbo and some post-turbo. could someone plesae clarify which one, is better to use?

also, what is the ideal length of manifold from cylinfer head to turbo? (inside diameter???)

so, after all of that, what material is best to use? anyone know the thickness gauge of material to use? (durability)

thanks for all of your help.
