Figured I should do things legitimately since I had this motor out.
-10AN fitting welded into the pan with a -10AN nylon drain:
-6AN bung welded into the mixing manifold, with 3/8" hardline for the coolant feed/return to turbo:
Since the 99 block doesn't have the M12x1.25 port on the side, we tapped the aluminum port that's normally for the coolant feed to the oil mixer and placed the feed line to the turbo there:
We also elected to use the 99 water neck vs. a 1.6 water neck, since the 1.6 water neck doesn't allow me to use the stock temp sensor port. Puts the coolant up a little high, but if need be I can add a secondary cap next to the intake manifold to bleed the system.
Drilled and tapped the head for a heater core feed as well:
Not too much more to do now. Waiting on the Tunertoys BSP adapter to get the feed line hooked up, and other than that it's about ready to drop back into the car.
Look at the pictures / I am ready to debate
