quick question about how to get coolant to my turbo on my 16v 4age. i am running genuine rwd water inlet outlet and thermostat setup with no heater btw.

im just not sure of the flow of the coolant through the engine. by this i mean should i feed the coolant from the small pipe that comes out of the back of the thermostat which is located at the front of the engine or does the coolant flow the opposite way and i should run the coolant feed from the rear of the head.

here is the picture for reference.

rear outlet


any help would be appreciated as i would like to finish this engine off these holidays and get my cooler piping fabricated.

also where would i put the coolant return into?


cheers
