There should be a hose that comes off of the passenger head that feeds an inlet tube that is below the banjo connection on the turbo. same style connector as the one that is there but heads down and towards the top of the picture under the turbo to a short hose that connects to a hard line that goes on to the head. That is the inlet turbo cooling line.

 

The one that is u shaped in your picture goes straight out with about a 5 inch hose to the other connection that you have marked in your second picture. That one leads back into the cooling system right before the thermostat housing.

They must have had an extra coolant tank of something plumbed in there.

 

 

If you can't get it figured out let me know and I will run out to the wifes car and shoot a picture for you.

 

One problem with the way that it is hooked up originally is that the passengers head runs hotter that the drivers head because of a design flaw in the engine that slows cooling to the passengers head.

 

On my turbo (have the engine out and can take pictures of what I am talking about if you want) I changed it around to run the coolant inlet line from the drivers head.

Turbo outlet hose hooked up.

Turbo water pipes not hooked to the turbo.

Top goes to thermostat housing.

Bottom goes to passenger head under the turbo.

Oil inlet and outlet as they connect to the head.

Not sure what aluminum part you mentioned.

Are you adding a Water cooled turbo to this car?

 

I thought EA81t used an oil cooled only turbo?

 

 

EA82 trubo water supply comes out off the drain bolt in the bottom of the passenger side head, then comes up and under the uppipe flange.

I did not even catch that Gloyale. I think you are right. All he needs to do to run it is cap the ends. What he needs to do is route his heater core lines over to the turbo like I did on my 84 coupe.

No,that is not right.
The empty fitting in the 2nd picture is the intake air source for the AAV(auxilary air valve).
It connects via a U-shaped hose(8075 12112 officialy,12 x19 mm,about $15,you want fuel/oil resistant hose for this one) to the AAV(auxilary air valve,the black square thing) that you have connected to the turbo at present.That is not a water line.
Take the RH hose off the turbo and bend it up to the fitting if possible.


I have the upper turbo water line Teed into a heater line.
Lower goes down to the bottom of the RH head.I improvised a heat shield.

Turbosubarubrat your car did not come with a water cooled turbo (you are using an EA82 turbo) so to use it you have to be a little bit creative to run cooling lines for it. I just ran T,s at my heater hoses and used it that way but it sounds like naru found a return spot on the RH head to to tap into. I may have to look into that myself.
