Situation:
Got my turbo kit in and running but now im missing an oil restrictor.
Turbo is off a r32 skyline (rb26dett) and it is a journal bearing turbo.

Problem:
I have established that i need an oil restrictor but i can't find the right size!
I've tried a few that my friends here have gave to try but they are all too small.
I think since it is a japanese turbo is is also metric.

Below i have provided some pics, maybe you guys can determine what the right size and thread or an oil restrictor i need.

I don't want to make one myself because i dont want to mess it up. I know places like ATP Turbo's and other vendors carrry them, but i can't order if i don't know the size. I also don't know the thread of the oil line kit, it was ordered a while ago from my friend and can't find the site or paperwork.

This is the last piece i need to get my car tuned, i miss driving the stupid thing so please help!

 

bb is usually .0045 and journal .0065

 

^ didn't mean the size of the hole on the restrictor, but the restrictor size itself in terms of NPT , -3an/4an etc, those types of measurements.

 

u mean like 1/8 or 1/4 ect

 

i try to fit my 1/4 fitting on a same turbo like this last night and it was just a little bigger.

i would say a step down from 1/4"

 

atpturbo sells them.. I thought journal bearing turbos don't use restrictors..

 

they sell them but i need to know what size this is first..
