OK on a b16a2 whats the o2 sensor location on the front of the header or on the rear section the header...... Does anyone know.. Does it matter what location it goes in... Or does it depend on what ecu type...Like obd 1 or obd 2... Any theories on it.

 

at teh rear of the headers, there shoudl eb a hole that it screws into, kinda just below the intake manifold...

 

But the header i have has two one on front and rear or is that because the make of header

 

if you are using a 4 wire heated oxygen sensor it needs to go at the rear of the headers, not the front if it is OBD1.

(if it is OBD0 the two o2 sensors need to go closer to the exhaust ports on teh head.)

 

cover up the second hole with scotch tape

 

where is it located on a 94 gsr? i looked at the end of my header and i didnt see anything. do i need to take off my heat sheild?
