I have seen some fast boosted B series engines. But I have to say that your particular B series engine is not the most ideal to boost. You have high compression, a thicker head gasket will distort your quench along with lowering your CR. You would be better off swapping a H22 or a LS and turboing one of them. And I am sure that your cams arent going to have turbo friendly overlap....

I wonder why MugenT3/T4 dropped his turbo Type-R like it was hot. He could have stuck with a NA type-r and would have been alot better then with a new SI.

Type-Rs have their place as cars, but turbos dont have a place on them. It wasnt in the cards.
