Default CHRA thread sizes

I am getting ready to order some fittings for my car. I am going to run -4 braided stainless lines for my water lines to the turbo and my wastegate. I have all the fittings for the wastegate, because they came with it. The turbo CHRA is a different story. What size are the fittings for the water ports? This is a standard SR20 CHRA. When I used to run a standard SR20 turbo, the one side I used the stock banjo fitting. The other side was I believe 1/4" NPT to 5/16" barb. I used rubber lines before...not this time.
Is it pipe thread? Or something else? It looks like it has a taper to it like pipe thread should, but then again it doesn't? The banjo bolt definately isn't pipe thread...is it metric? HELP!!

Lol, so it is bolt thread.
I went for like 4 years with a 1/4" pipe fitting in one side with no issues.
It's time to sort this setup out right and get away from the rigged up.
