I've recently bought a gsr swapped 98 hb. I need to replace the IACV gasket, but am unsure of which one I need. The motor has the Skunk2 intake manifold and I assume the gsr IACV, but I'm not sure as I didn't do the swap. The IACV gasket for the gsr is p/n is 36455-PV0-000 and the ITR & Civic Si share p/n 36455-PT3-A01. Does anyone know if these parts are interchangeable or if they are actually slightly different? I've considered just buying them both, but I'm cheap so I'd like to figure it out beforehand... Thanks for any help.

 

Not 100% on this but I think the GSR used 2 different (very close) IAVC's. The holes that allow air to the manifold are different but the gaskets are the same. Can't speak personally for the ITR's and si's but I thought that all the obd2 DOHC's were the same. If you have the old gasket just bring it in with you to be sure. Thats what I would do.
