I just pulled off my stock twins and found 1 supply and 1 return for oils as well as for coolant. It doesnt'l look like the circulation is very good because the supply and retun are in the same hole. Can anyone confrim that these turbos are coolant cooled?
yes they are. there is a water in, water out, and oil in, oil out on each turbo. the water feed comes straight from the pipe going to the upper radiator hose.
