Garrett 2560 Oil Supply Fitting Issues
I am in the middle of my first turbo build and I am having some doubts about the 7/16" -24 Male Inverted Flare fitting that I bought for the turbo oil inlet. The threads are correct, but it bottoms out well before the nut reaches the turbo. The way it sits, I would not be able to use a crush washer and it would leak a lot. Am I missing something? Is there somewhere that I can buy a fitting that is not as long so that the nut actually bottoms out?
Also, does anyone know if I will need a restrictor for this turbo? It is a journal brearing model and I cannot find any definitive information online about restrictors for it.
Oil inlet fitting, it is bottomed out in this picture:
Oil inlet without fitting, it looks like there may already be a restrictor there but this is the first time I have ever dealt with turbos so I am not sure!
Thanks in advance for the help!

Thanks guys, I see that the flares would match up, but it just seemed weird to me that it bottomed out so early. Also, the fitting that was on this turbo before I bought it appears to have used a washer to seal the fitting.
I did search before posting this thread, but I was not able to find any specific information or pictures on how the fitting should look on the turbo. My searches just give me inverted flare fittings for sale. Could someone point me in the right direction for search this topic?
Thanks!

Flare fittings seal at the flare face. It's fine if the threads don't bottom
Just make sure the conical seat at the bottom of the port of the turbo matches and engages the flare on the fitting. It's an inverted flare, so the male threaded fitting has a "female" flare and vice-versa.

Thanks guys! That makes sense. I was unsure and could not find my answer online.

Most of the info when you Google flare fittings is about differentiating different types of flares. Not as much in the way of explaining the very basics of what flare fittings are.
The left image is an inverted flare. The bottom corresponds with the turbo. You have an adapter with the matching geometry in place of a flared tube & tube nut.

Also, when I type the numbers on my turbo's tag into Garrett's site no information is found.

As far as I have seen, 4 bolt = JB, 6 bolt = BB for Garrett small frame turbos.
edit: and don't go to garrett for archive information. Google the number ... the garrett number will usually be the 6 digit number (ex 466543-2) and the manufacturer nuber will be something like 14411-05u20 (nissan).
those 240sx/silva guys have some good nissan info
