It is 1/8 BSPT

Its a british pipe thread, its soooo close to 1/8 NPT only not. I would drill it for 1/8 NPT tho, because its easier when your shopping for fittings to get 1/8 NPT. All I did was run a 1/8 NPT tap right over the existing threads and it worked fine. Even if you intend on using stock EVO lines, I dont see why you cant tap it for 1/8 NPT and just buy a NPT threaded banjo bolt so it would be compatible. Other than a professional machine shop, I dont know who would have a 1/8 BSPT tap. I have a $600 Snap On tap and die set, and it aint in there.

Hey on the back of your Sonata head, is there a recessed hole that is plugged up and covered by the intake manifold? EVO's have this hole, Im just saying you can use it for comparison because its only 1/8 BSPT or BPT whatever they call the british thread.

What type of turbo are you going to feed with oil from the head?
