My H22 didn't come with the IAB and I read somewhere that you can use one from a GSR if you can't find the one from a Prelude, my question is has anyone done this or should I just do it and see if it works out?? Any clarification on this would be greatly appreciated.

 

Are you talking about the IAB solenoid & the vacuum reservoir? That'll probably work.

Or does your H22 have an intake manifold without the secondaries? I doubt a B18C1 intake manifold would fit.

 

I am talking about the IAB solenoid & reservor. Thanks for the response Jim.
