SR20DET Turbo Elbow O2 Sensor Bung

[KawBoy]

Doesn't the Redtop SR20DET use a different O2 Sensor then a blacktop? Now when you purchase a turbo elbow, do you have to make sure the O2 sensor bung is for the Redtop or Blacktop or what? Because from what I seen the turbo elbows seem to use only the fat type "black top" o2 sensor. So if you wanted to run a redtop ECU and O2 sensor, what would you do for the turbo elbow/o2 sensor?

Thanks :)

thread wise they are the same size, its only the sensor tip that is different size

Really?

Looked like different thread to me

"The early SRs have 12mm threads, the later ones have 18mm threads." is what I found

Depends on the elbow you get. If it's threaded for the fat o2 sensor and your running a skinny one you can order a adapter from Megan Racing for like $10.00. If you can weld you can grind off the bung for the fat o2 and take a open lugnut and weld it on. The thread pitch is the same. It's 12x1.25 so just weld it on and grind it down a little so the sensor can still stay in the exhaust stream to read accurately and there you go...:bigok:

Oh, try not to get the divorced pipe so you won't have steering rack clearance issues. Try to find the solid elbow.

Im running a 62 Ecu in my blacktop.. so I'm guessing the blacktop fat o2 doesnt work as well with it, and the skinny would be better to match the ECU? I might just get the E5 but I figured a 62 would be easier for tuning

Thanks for the help so far
