ok so i have a low 240 with a ka and 2 months ago i snapped the downpipe off the manifold. so to fix it i bought a greddy header from a fellow zilvian. but i have run into a few snags,

the header is for an s14 and the o2 is completly different from the one that i currently have. so basically i have a my stock one which wont fit in the hole in the header. and i have the one that came with the header that wont plug in any where becouse it is a four wire connecter.


i have no idea what to do at thios point any ideas would be greatl;y appriciated

Cut off the bung and weld in the correct size that you need? Or maybe sell it and buy a cheap Hotshot header off ebay? I've never owned an S13 (which i assume is what you own) only S14 for me, so I don't personally know the difference in O2 fittings between the 2.
Maybe the header you got was from an OBD2 S14 (1996+)??

hmmm i might be able to redrill and tap the hole to fit my orginal o2 sensor

another question.... what will it effect if the o2 sensor is there but not plugged in. so basically the cpu is not getting a response from it?

O2 isn't there for show buddy. Def need to have one (OBD1) or 2 (OBD2) plugged in to keep the car running well. Don't let a good deal on an exhaust header be the death of your engine. :( It'll run like asssssss without one.

What year is your current motor vs your exhaust manifold intended motor?
Looks like you have an S13 OBD1 that you are trying to make work with a S14 96+. If it's OBD2 there will be another port further down the header.

Maybe just buy the appropriate O2 sensor and wire it in??
