I've searched and Google'd but I can't seem to find a definite answer. What are the threads on a t28 journal bearing turbo not the bb. I'm trying to buy an adapter from the oil Intel to a -4an. I think it is m11x1 threads (7/16-24) but not hundred percent sure. And for an oil restrictor can I just use a -4an male to female .06. Then an adapter from -4an to whatever the turbo inlet is? Sorry if it's been covered but I can't find any solid info on it.

You are indeed correct, it is the 7/16"-24

Ok thank you is it ok to use a 4an restrictor right before the 7/16 to 4an adapter on the oil inlet ?

You can buy the fitting with a restrictor from kinagawa. Just make sure you choose the correct one. It will list BB or journal bearing.

So I ended up buying an unrestricted adapter from the oil feed hose to the turbo. And I bought the 4an male to female restrictor .03. My friend works at a machine shop so I'll just have him drill it out to .06. Thanks for all the help! It might be time for me to start a build thread. This 99 will be boosted in no time.

I wasn't sure about the adapter with the jets cuz it didn't list the size of them.
