Need help with fitting sizes. (Pic heavy)
Looks like the oil inlet fitting that I got with my turbo wasn't exactly the right size. I had a pretty steady leak between the adapter and the turbine housing when I started it up. I felt like it was going in correctly so I tightened it up. Anybody have any idea what size the inlet on the turbine and my oil line is? I bought all of the stuff off of someone so I don't know what kind of oil line kit it is or the fitting sizes. As for the turbo all I was told was that it was a garrett T25 turbo. If anyone knows the fitting sizes that would great or even if they could just identify the turbo for me so I can email online shops. I don't know of anywhere locally that could even determine the thread sizes for me. Most places around here only handle the standard sized stuff. Besides it looks like the threads inside the turbo are to messed up that even if I found the right fitting it wouldn't feel right going in. I'd have to know it's the right fitting and just force it in there. Maybe JB afterwards just to be sure. Here are some pics:
Compressor side
Exhaust side
The stripped fitting
The fitting again. Think I should use a restrictor?
Various pics of the inlet on the turbo plus the stamped plate for id'ing.

Anything, guys? Doesn't even have to be exact. Even if it's just a good guess. I'm even willing to buy a couple different fittings with the hope that one will work. So long as I can narrow it down just a little.

What you should do is take the turbo down to a local hydrualics/hose shop and get the right fitting.It is probably 7/16 inverted flare,1/8 NPT or metric[take a couple bolts from store and try them].

I have the same turbo. Its 7/16 24 thread for inlet and 44.45 spacing on the outlet bolts. Steve told me its a T25 kit I needed and thats what he is sending me. Its a tiny turbo. It has a T3 inlet right? Mine does but a 4 bolt outlet.

Look at the T25 listing. Looks like you may have a 14b kit.

The threads in the turbo housing don't look too bad. In the 2nd to last pic I can see a metal chip/fucked up thread. Make sure no metal shavings can work they're way out down into the bearing housing

Re: Need help with fitting sizes. (Pic heavy)
Actually with what 90dx said reminded me. We do have a hydraulics/hoses shop here. I actually had to go there earlier for some female 5/8" with a 1/2" hose barb. Completely forgot about them. I'll have to bring it by there on monday. So it is a T25 then, right? I knew it was a smaller turbo but never knew if it was a gt-25, 14b or any of the other small turbos. Any idea what kind of car this came out of?
BTW are those fittings/adapters something a hydraulic/hose shop would have or are they specially machined on those turbo sites?
