what? it doesnt really matter, route it however you like to make it the cleanest. engine to core from core to valve and from valve back to engine behind the turbos is cleanest routing..
i needed to know what hoses to use, i bought the supra tt heater hoses and am kind of confused on which ones go where. there are a total of 3 of them. i wanted to know if anyone with a gte swap could take a pic of how their heater hoses are connected so i can have a visual to go off of.
I used the origional SC hoses for the lines that go to the heater valve. The only hose I had replaced with the supra TT hose was the one that goes to the drivers side heater core inlet/outlet to the hard line coming from the back of the turbo. Hope this helps.
Thank you guys, so the hose from the back on the head goes to the side of the heater control valve, then the pass side heater hose goes to the lower part of the heater valve and the drivers heater hose goes to the line for the rear turbos.
