Had some progress and some set-back today.
Here's the system drawing off what I am working to adjust. Highlighted sections are involved.
I removed the EGR valve and made a block off plate.
Pick showing the -AN oil feed line on the turbo side
Downpipe installed

O2 sensor installed. Note on the left side is the plugged bung for a wideband O2 sensor. LOTS of Anti-seize used on threads.
Onto working out installing the plumbing from the Air Flow Meter to the turbo inlet.
This is the area I have run into some clearance issues I have to sort out. There is some interference issues I need to address which = space issue and the only way to resolve is via moving a welded bung about 1". Ugh. So close, yet so far. Don't you hate when math fails you? Actually, math was fine, but I missed something else that is causing the interference, so time to adjust.
Still, working on hooking up everything else I can. More work tomorrow.
