So my K20a build is almost complete but trying to figure how to route coolant lines for GTX3076R Gen II turbo.
I'm waiting for connectors and hoses from Honda that routes coolant as in marked picture below, which I belive is for the heater. Can I just route one side into the turbo and the other side back or use the oil cooler in the second picture?
The two ports in your first pic ARE the "in" and "out" ports for the oil cooler itself. I don't think I would run the turbo circuit through the oil cooler circuit... this will reduce the effectiveness of the factory oil cooler... and it isn't particularly great to begin with. I would "T" into the heater core lines... found at the top left of your second picture.
Found this in one of your old posts, but I'm still trying to translate this into actual layout on the engine it self.

From the photo that you have just posted... I would disconnect the blue arrow hose from the throttle body and connect it to the turbo coolant inlet instead. Then connect the turbo coolant exit port with a similar hose back to the throttle body.
m14x1.5 like oem size on chra. you can use 2 art of return. weld an bung m14x1.5 on radiator or delete idle air assi on intake manifold and install a npt fitting with hose connector. there some k tuned fitting size for this assi.
Engine's all back together now and I've figured the connections from the diagram posted, mainly cause I've installed a SK2 throttle body and it doesn't have the coolant input or output ports. My new question, is which directly does the coolant flow from? Does it come in through the line with the blue arrow and exit back through the line with the read arrow or is the other way round?
