im about to install 2 new o2 bungs on my downpipe and was wondering where would be the best place to mount them, such ***
right near the firewall or near the beginning of the downpipe
and should i put the o2 sensor before or after the wideband sensor
and if they should be spaced apart within a certain distance

would the readings be any different or better?

this is going on a 2.5"dp for a turbo sohc

thanks, tony...

 

wideband should be installed 18inches or more downstream from the exhaust valves according to FJO

i wouldnt put the o2 right in front or the wbo2 or visa versa so they dont interfere with the exhaust flow of eachother (not sure how much effect it would actually have)

IMO just mount them its easy accessible locations less the 24in from the head

 

I've also read from several sources that the WB O2 sensor must be mounted with the end at least 10° up from the horizontal so that water vapor doesn't puddle in the Nernst cell!

 

hmmm all this is getting interesting like research, anyone else have anymore input? not as simple as i thought it i wanted it done good

 

more input neeeded
