What needs to be done to fit a B18c header to a B17a on a '92 integra? Cutting? Bending? Forget it?

forget it i belive that the bolt pattern is different on it but if you got the part already to go use the trial and error method. take yoursoff and try to put the b18c on if it fits it works. but im sure it wont fit. or best take off your head gasket and the one off of the b18. (or just go to autozone and ask the guy if he could compare the two exhaust manifold gaskets for you so you could see the differences in the bolt patterns. all in all even if you do get them to match up there might be some type of leaks.

 

I am pretty sure the bolt patterns are the same on the exhaust flange... I am thinking that the clearence on frame parts or mounting brackets
Thanks

Primary sections of B-series exhaust manifolds are all the same for all engine that use the cast iron primary manifolds.
