Where the blue vacuum lines connect here, to the black tube where his thumb is - I broke one of the two "nubs" that are sticking out that connect to the blue lines.
After much painstaking research, I found the part #11666769086 - it's part of the "Brake servo unit", which is odd. Apparently it's a pressure tube that's shared between both that creates a vacuum.
Looks like I will be able to replace it fairly easily (surprisingly) with the part, which was less than $30 at my local dealer.
Currently, the car is drivable but it sputters and shakes a little, which I'm hoping is completely due to the loss of vacuum power in the turbos. If not, I'll have to look at my coil packs again as perhaps I didn't seat them properly? It drives worse when I accelerate more than a snail's pace, but once I'm up to speed it is fine.
