So got most of the plumbing done today except for the coolant return because I need to dig the radiator hose out to measure out the AN line and install the bulkhead fitting.

Nice pretty front shot of the 6AN coolant inlet line (top) to the turbo and the 10AN oil return to the pan (bottom)


4AN oil feed and 6AN coolant lines

Last step of the puzzle really is getting this wastegate flange welded up to mount the wastegate. Pretty much just need to cut the 45 degree 1.75" pipe and weld it to the flange I just finished drilling out last night. Turns out using a hole saw on a hand drill on .25" plate steel is pretty difficult haha. My biggest worry at the moment is that the plate is mild steel and the pipe is stainless and I only have mild steel filler rod so we'll see if this flange holds up at all with these welds.
