02 sensor location - STD manifold
 

Hello, I'm getting my DP and intercooler piping welded next week and am wondering if I should make a bung for my o2 sensor in my DP or use the stock location in the STD manifold

I figured the high EGT will fry the sensor in the stock location and I'm better to just weld it shut and make a new hole in the DP.

Any ideas?

Re:02 sensor location - STD manifold
 

I would recommend the o2 sensor being after the turbo, either in the downpipe or a housing immediately after the turbo (like how dsms have an O2 sensor housing that connects from turbo to dp).

Some people will argue me on this, but you can do what you want.

instead of welding the hole shut I've seen guys weld in a probe for an egt gauge

Re:02 sensor location - STD manifold
 

Yeah, that would be senseless to weld that hole shut. Just get something to fill the hole.. if it's standard o2 sesnor size then it's 18mmx1.5

Just stick a plug in there or something classy like a spark plug. You could always use it for an EGT probe at a later point in time, it's the ideal location.

thats a good idea on the spark plug put a plug wire on it too running to a secret hidden place and say its ur after burner....lol

Re:02 sensor location - STD manifold
 

sparkplug, bolt.. whatever works - as long as it's 18mmx1.5

Re:02 sensor location - STD manifold
 

i was being serious you wouldnt think to just shove a sparkplug in there maybe a old o2

Re:02 sensor location - STD manifold
 

02 sensors have to be after the turbo. idealy 5-8 inchesz after the turbine wheel. to close and itll behave like an EGT.

I thought I saw this topic before and the general consesus was to keep the O2 right smack dab in the center of the manifold... before the turbo ???

I have mine in it's original location and it seems to work fine... I do have an O2 bung on the downpipe as well for a wideband, but it's plugged otherwise.

WTF?

Re:02 sensor location - STD manifold
 

one question, where did honda put the o2 sensor and there is ur answer ;)

Re:02 sensor location - STD manifold
 

Honda put the sensor there in the first place. I would leave it where they intended.

Also, if it's a 1-wire sensor it will heat up quicker in the oem spot as well.

Re:02 sensor location - STD manifold
 

i've got mine in the manifold before the turbo. sometimes i get a CEL for the o2 sensor but i just flick the key off real quick and it goes away ;) its a new o2 sensor.

Re:02 sensor location - STD manifold
 

i have my O2 in the mani...no problem.

Re:02 sensor location - STD manifold
 

I'm keeping mine in the Middle of the manifold. There has probably never been a serious conflict w/using the stock O2 position, so why worry about it? Unless it is bothering you, I say forget about it, why complicate things where it's not necessary...

I have a lot of research on this at my home computer, I'll have to post it up sometime.
