Yeah - I run one of these (It may be sliigggghhhhhtttlllyyyy different) and a JWT spacer…I also welded on a small sump box for my turbo.
The ports are used for turbo (likely twin turbo) oil scavenge deposit back to the oil pan.
I like mine, I “joan-rivers’d” mine pretty well but between the bigger oil pan, the spacer, the cooler, and a mile of hose I run about 8quarts of oil in my system.
