This Is specifically made for S400's like what we use on our 6.0 compound turbo kits but works on most mid/large frame turbos. We use an o-ring flange made by Fleece Performance, a thread in ORB adapter, and stainless steel 12point ARP bolts for a clean, low profile look.
This uses M8x1.25 thread pitch which is what most mid and large frame turbos use.
This is -10AN and matches our drain line kits perfectly.
