The fitting is 30mmx1.5. I plugged off the existing hole and took a nut with the same thread pitch, grinded a radius on the one side, drilled the pipe with a hole saw and welded the nut on. It makes it a lot nicer to fit an intake.
Also I studded the pedestal to make it a lot easier for turbo swaps. 10mmx1.5. Get Grade 10.9 and red loctite them into the pedastal it makes it nice!
