For everyone's info:OBX header for s14 (I'm pretty sure its for that model as it had 2 bungs for O2 sensors) will interfere with the steering on an s13.At first I thought it was just from a poorly cutoff bung, but it turns out if the engine is seated correctly (say with new motor mounts that you can't move around with your fingers) the secondary tube from cylinders 1 & 4 will rub against the linkage making it very dangerous to drive as it locks the steering. You can muscle it through, but I can't imagine this to be good for the steering.

Don't they make seperate models for the S13 and S14? Pretty sure they do.

Yes they do have different models. The guy who "rebuilt" my engine ordered the wrong part which does not work. I just thought I'd pass on the info so no one tries to mix-n-match

I guess you cant read he just stated he was not *** who ordered the wrong part. He was just stating this before you tryed a s14 header on your car.
