i would get used stock engine parts from a newer integra type-R. lots of parts will fit, intake, throttle, exhaust manifold. vtec heads too if your up to the labor/dollars/hp.
these parts pose little risk to the engine unlike nos, and are easy to install
the b20a is the adopted bastard stepchild of the b series family. no other b series parts will fit it.
