when putting a turbo on a 2.4, where does the o2 sensor go, is there a spot to put one on already on the manifold or do u need to custom weld one on . and would it be on the manifold or downpipe?

I'll assume your talking about an o2 sensor for a wideband. If so, its supposed to go between 12-16 inches down the downpipe (from the turbo outlet). If you're just talking about the primary o2 sensor, I'd assume somewhere around the original factory placing would be okay. I usually see people putting the primary and wideband sensors side by side in the downpipe.



Blew it up, build numbers coming soon
