Does anyone know which header would be the best one to use with a '94 JDM B18C GSR swap into a '91 CRX Si with a PR3 ECU for only one oxygen sensor? I am not brand particular and I am sure that some are better than others. I am on a tight budget and plan to buy the OBX. I did a search, but can't find a good answer. I was told that the '91 Integra LS header would be the best as it has only one bung hole (yeah, I said bung hole) for the oxygen sensor and the length would be right for my CRX factory catalytic converter. I ordered it from Massive Motorsports and they are telling me that it will not fit. Does anyone know? I read that the GSR header is shorter and requires an additional pipe or a longer catalytic converter. I posted this on Hybrid a few hours ago and have had no hits. I am hoping someone here can help. Please help me!! Engine is in and most of the wiring is done. I think I would be rolling this weekend if I had the header.

the ls header wont hit the crossmember (its 2 peace) but i think just about every outher will (at least the ones i see) but it does not hit buy munch if your looking for the max profamce go with the gsr, it you can stand not haveing the max but want the ease of fit then go with the ls well that is my .02

 

I am running a JDM ITR header on mine. If I remember right the only thing we had to do was modify the front cross member to get it to clear. Other than that it was easy, and it is one of the better headers out there.
