Help me find OCX header number?

[bernard_nj]

This is my first post. I am trying to help my 18 year old son who just bought a 1990 GSX with a newly rebuilt 4G63. He also got this exhaust OCX manifold, with two ports, but it does not fit the turbo in the car. OCX was no help in finding a part number. Can anyone give me a hint what this might be? Or tell me what website might show this part? Thanks.

ill tell you that the manifold you pictured is a different flange then stock dsm turbos are. the manifold u pictured i believe is a t3/4 flange. with a brand name like ocx i wouldnt even bother putting it on any car. best bet try to return and look threw the classifieds for 2g mani. they can usually be had for 50 bucks depending on the condition

First try reading the letters on the flange and you'd realize it's an OBX not an OCX. Contacting the right company may help you out.

To help you out though that's most likely a T3 flanged OBX manifold and the little outlet is for mounting the external wastegate.

Thanks to both of you. I will now call OBX again with your hints.
