swap info:
1st gen b16a into 94 del sol si (originally d16z6)

problem:
i have searched and searched and have found nothing that i am looking for yet. i might just be "search-challenged" but i can't find anything to help me out here. i have 2 o2 sensors in my exahust manifold, as you well know, and my car only originally came with one o2 sensor in the bottom of the manifold/header. i have read that i need to run an extra wire for this second sensor and i have also read that i need to convert to a 2/4 wire something or other?

basically, i just need some info on this from someone that actually knows rather than my stupid *** trying to find something and getting nowhere/it being the wrong info.

gotta get this thing running in 2 days or less, so any info is GREATLY appreciated.
thanks

 

one goes on the cat.

 

what if one doesn't have a cat? (not saying that i don't :wink wink

BOTH of them are in the exhaust manifold/header. one has a round plug, the other is squared. what do i do to make both function?

 

if i remmeber correctly, for an obd1 car, you only need one in the header. the one for the cat doesnt do **** unless u have obd2. even then, you could just do an o2sim.

 

Have a bung welded to your test pipe. When I had my eg6 I recall it having 2 o2's. I still have my old cat with the sensor stuck in it as a matter of fact.

 

if you got the obd2 you could get a secondary o2 sensor eleminitor thingy other wise you just need the one

 

yes, that is what an o2sim is

Something doesnt add up right. Your OBDI should not have 2 o2 sensors. you should only have 1

 

Maybe its for the japanese model. Because when I had my car over seas I had one on the header and one on the cat.

 

then y arent people throwing CEL with the JDM p30 ecu that comes with there swaps. and most people run the DC sports with 1 o2 sensor

 

If you read this right he is asking if he needs another O2 sensor, the car only has ONE and the exhaust mainfold has 2 holes.


answer = weld one up so the hole is closed and use the other one for your Sensor

i have a jdm b16 exhust manifold upper half on my gsr and it has two sensors side by side on the back of the header. i just plugged in the one i knew was an o2 sensor and just left the othere thing in there to take up space

 

i considered that but would that matter that it would only read 2 cylinders instead of all 4 (like it used to?)

 

what ecu are you using for the swap? what kind of exhaust manifold are you using?

 

i have a p30 or a chipped p28 to use....not sure which one yet but i would rather use the p28 i think.

exahaust manifold is the stock JDM 1st gen b16a manifold.

 

p30 or p28 is obd1 only required 1 o2 sensor. as for you manifold got 2 holes like early post had stated you need to cap one and use one for the o2 sensor.

 

alright thanks
