hey guys i was wondering if i could use my obd 1 integra injectors and fuel rail on the b20 intake manifold? right now on my b20b i have the b18a( DA integra) manifold and it has the fitv and i want to put back the original b20 intake manifold to get rid of the fitv. and for the throttle body do i just use a b20 one or can i use my integra one?

this is the b20b intake manifold that is stamped p75, it is not the long giraffe style one.

any help would be greatly appreciated.
