Hey I'm switching a car to fuel injection and I need to drill an O2 sensor any suggestions things I need to look out for before I start... I figured it would be pretty straight forward but I wanted to check first.

 

your gonna want to get an o2 sensor bung welded on, most shops will do it for 20-30 bucks. and its usually guaranteed, dont just drill a dole in your header and tap a o2 sensor in, it wont work.

 

Yeah,I was going to wield it on myself... I was wondering more about placement etc... it's going into rb headers...

 

go between the end of the tubes and the collector.
