I will crawl under there again. I recall seeing only one pipe from the manifold to the turbo. How thick is the wall on this pipe? I assume it is thick enough to tap threads in it to get the egt probe to bite???????

 

If I had to guess I would say 1/4" to 3/8" thick. Definately thick enough to tap.

 

I am going to assume that based off of the thicknesses that you list, you are describing the thickness of the exhaust manifold walls and not the pipe that runs from the manifold up to the turbo. Please bear with me on all the questions, I don't want to screw this up.

 

Yes ........the thickness of the walls.
