so i picked up a set of used 4-2-1 megan racing headers for my da [stock b18a1]
the guy i got them from had them on a 94 ls

they only have one bung for the o2 sensor on the down pipe or 2-1 pipe

but when i inspected my stock header it had the o2 sensor near the top
of the header.

so my question is does my engine use 2 o2 sensors?
or just the one up top, and if so will it be able to reach all the way to the
end of the 2nd pipe?

thanks for any input guys.

 

you can just splice the o2 sensor wires and make the wires longer , with some speaker wire or sum

 

i heard that messes up the o2 sensor and it will screw with my air/fuel ratio?

 

dood thats a trip cause i have a 93 teg with my o2 sensor like at the bottom and i have stock headers i wanted to get the megan racing ones and the price is reasonable...can u feel a diff in power and tone in exhaust i have a b18a1 as well

 

why dont you just block of the one drill and weld you a bung on it and not have to worry with wire hassle and still be located in the same spot

 

my 91 has it up top, i havent tried putting them on yet.

but if i do ill let you knw.
an i got them for 80 bucks.

 

i could do this, but extending the wires sounds easier.
thanks though. ill lift up my car tomorrow and try putting them on.

 

alright for sure im really interested in those headers cause im dieing to add something to my car and that is on my mind lol i want some headers...

 

dude i went on their website and found out they make different headers
for the 90-91 and 92-93 models.

aaarrrrrggg, if anything i can just buy an o2 sensor from the 92-93 models right?

or not?
cause arent 92-96 obdI???

confused.

help?
more input would be helpful guys.

 

if your integra is a 95 and down it uses one, if it's a 96 and up it uses two. Just plug one of them if your integra uses one.

 

90-91 is a single-wire o2 sensor. 92-93 is a three-wire.

So basically you're right...

 

good info.

im gonna lift my car up in a while and let you guys know how everything goes.
