s13 ka exhaust mani and second O2 sensor?

[d3vilskid]

I have a 95 240sx, my brother is planning to go turbo and is giving me his s13 aftermarket exhaust mani. If i was to use it i would have to get rid of my second O2 sensor. Will this cause a problem with power production or does it just deal with emissions?

The second O2 sensor is located behind the cat, so the S13 manifold will not effect it.

However, I am not 100% sure the S13 manifold will line up under the car with the rest of the system.

The S13 has a bung for the O2 sensor, and one for the AIV system. You would need to plug the AIV port. I actually used the threaded O2 sensor bung from my S14 manifold, threaded it into the AIV hole, then added a second O2 sensor to run my A/F gauge.

The S13 Manifold is a much better manifold, being it is like a long-tube Tri-Y setup, where as the S14 manifold is just a shorty.
