    Coolant flow diagram

    I have a Holset HY35 turbo en route for my project AAN. Since this turbo isn't water cooled I am going to remove the extra cooling circuit. I have made the assumtion that I can just convert the AAN to the 7A setup. Does anyone know if the coolant direction of flow is correct? If it is, does anyone have a diagram. I can find pics for the AAN but none for the 7A. Once again I'm assuming that I just need to remove the after run plumbing and all will be well. Let me know your opinions.

    why not just block the pipes that go to the turbo and leave it like that?

      I thought about that, but in the intereast of simplicity and weight reduction I figured it best to remove what I can.

        I will just block the line on the passenger side of the block though.
