Subaru Cooling, Bypass Cooling - No Heater Core Options

[turnaround89]

Hi Everyone,

I have an subaru EJ20 turbo engine that I'm working on getting into my car. Right now the main project is getting the coolant lines back into the engine compartment. I've made it that far and will be reinstalling the engine to hook up the cooling to the engine. However, my question comes from my potential (mis)understanding of how the cooling system should work. My question is about the two ports on the side of the water pump. I believe these are used for the heating system in the original car. All the fittings on the water pump are used as a bypass for the cooling system when the thermostat is closed. Does this sound correct?

Since my car won't have heat, I still need some type of bypass for when the thermostat is closed. What I'd like to know is if my potential idea will even work. My idea, is to leave 1 of the ports on the water pump plugged. And use the other as a return from the Turbo. What I'm hoping would happen, is the water pump would pump coolant to the oil filter/oil cooler, then from the oil filter/cooler the coolant would go the turbo bearing. Once the coolant reaches the turbo bearing outlet, it would go into the small tank on top of the engine. The tank has an outlet on the bottom which I was planning to route to one of the ports on side of the water pump.

Would this even work as a bypass or am I completely off on how to get the cooling system to work? Previously there was a port that came off the back coolant cross-over tube which is now blocked and is being used for the water temperature sensor location. I think this is where the small tank drained coolant back into the system. I think that off those 2 ports on the water pump, that I plugged for now, were some hard lines that went towards the top of the engine and then fed into the heat core.

Thank you for your help!
