you can probably plumb some A-N fittings from turbo to engine block. My block has a 1/2 pipe thread hole in the back that i have no clue what it's for. I believe one of the A-N fitting companies makes a adapter that bolts up to the oil return on the turbo then you just have to make up your steel braided line. You may of given me an idea for my next project. I will post pix if i get it done.
