an f22 is a 16 valve sohc with balance shaft. an 89 lude is b20a5 in si trim, 16 valve dohc with no balance shaft.
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
