What sixe orifice for a small T25 based turbo?

I'm about to get a oil restrictor for my motor (trying to get one -4an based so I can install to my existing line/before my oil gauge) but don't know which size. I have a GT17 t25 based .53/.49, should I get a .52 or .63 orifice?

I did a DIY oil restrictor on my t25... Drilled a 1/16 hole, which is comparable to .63 size...
I'd go with that, as .52 sounds really small. Mine was small enough as is.

Okay so .63 male x male oil restrictor. Problem is that I want one that I can thread onto my existing line and tee to a autometer oil gauge them to the turbo. They have 1/4" and 1/8NPT so which will thread onto the -4an oil line?
