Okay guys, so as some of you know I got a OBX header off of Buickboy a few days ago, and I have a couple of parts to collect before it goes on, but I have a few questions about the 02 sensors, and EGR system, since I will not be getting a tune right away.
Here are some pics of the header. Right now it has a bung on the collector, and one on the flex pipe.
Collector bung.
Flex pipe bung.
So for the most part, I think I know what I got to do, to be emissions legal, and have no cell without a tune.
I found this, and I think this is what I need to do. http://www.focusfanatics.com/forum/showthread.php?t=161467&highlight=obx+header+sensors
But my question are where do I need to put bungs, and the EGR pipe.
Now I have two o2 sensors that comes off the trans, one with a blue plug, and one with a grey plug. I believe the blue plug one is before the cat.
And I also have the one which I think is the primary, coming off the valve cover.
Now if I have everything right in my research, this is how it should look.
Green line: primary o2
Red lines: upper and lower o2's, which will require the parts in the link^.
Blue line: Is where I should weld the EGR pipe.
Am I right? Or do those upper and lower o2's need to be moved to the pipe next to it?
And I figure I would just plug up the collector bung, since I don't think I need it, and put my A/F wideband gauge in the flex pipe bung.
Thanks for the help guys, I've done my research, I just want to make sure with the pro's before I commit to having someone weld it all on.
