My problem is the PR3 ecu for the B16 is looking for 2 02 sensors and i need an exhaust header that has two bungs. Is there any available here in the North American market?
I am sure that there was plenty made for the JDM area. Anyone have one for sale?
I am located in the BC area.

 

Yes you can find them around, try http://www.hmotorsonline.com, why not just buy the american header and have then weld another bung in ?

 

I think that i will. I was just curious about the pairing of the cylinders for the 02 sensors and the location of the sensors themselves.
If I could get better performance with a well designed header over makeshifting a US header then it might be worth it.
Thanks for the info.

JUST get a muffler shop to weld them....they are 18mm fine thread or cut some bungs off of other old like junkyard hondas and use their bungs. i have doone that 3 times for b16a & crvtecs...

 

o2 sensors should be located about 12 in. "downstream" of the head, on header and some say the 2 allow for twin bank tuning of two cylinders each

 

So, which o2 sensor goes where? Can I run just one sensor in the collector of a JDM ITR replica? Will it work w/no CEL's or drivability prob's????
After I figure this out, I will just have to find a way to make it fit.(read: hack the sh#t out of my front crossmember)haha doesnt make me too happy but.........

 

You will need to run both, or else you will have a code. And I have cut my cross member and have not noticed anything bad from cutting it.

 

so use the number one and number three header pipe...also k member gets weak if you cut it down...what about z ten or place racing replacement k member

On a stock header the 02 sensor is on header pipe number 1 and , not 3. And even if you cut your cross member, I highly doubt you will even notice it is cut.

 

we were talking about doing it with two o2 sensors so that would be the correct position that i stated - please read the words, so it would be on the #1 and the #3 primary header tube as stated
