thread pitch size 4 blocks turbo oil drain?

[260sr20]

Im sorry if these seem silly. Need to order parts for next week, and live far away from the project. Also the search tool has not been kind to me.

This is for a black top sr20det s13

Building a -an oil drain line for a turbo. I am not sure of the thread pitch for the turbo's oil drain fitting that screws in to the block. Does anyone know?

Does any one know the thread pitch for the three lower vaccum ports on the bottom of the freddy intake?

Thanks
