do i have a turbo manifold for a 95 integra LS and i hear that the exhaust manifold are the for a gsr so it would fit a gsr.. but wondering if my turbo manifold would fit a JDM type engine B18C.... would it bolt up as well???

 

B-series cylinder head flanges are all the same, so yes, it will fit.

 

you said flanges but im asking if the gasket side of the exhaust manifold would fit. like where the head bolts to the exhaust manifold of aka header

 

That is the head/er flange.
