pretty certain it is a standard 9/16 cuttoff to -6 fitting if you are going to run -AN lines.

thats what it is on mine.

edit:

then again you said oil, that 9/16 is for water.

i cant remember what the oil one is come to think of it, i have a 90deg converter that makes it a -4 so i guess i dont remember.

i can go look though

it looks like a 11 mm with a 1 mm pitch from looking at it with the calipers.
mabye someone can confirm that as i didnt have any known bolt to compare it too.

Why don’t you just get a bolt and thread it in and see if it fits?
Do you even have the turbo? Why not just test it out instead of asking people for 5 days? It could only take like 15 seconds?

What if you don't have anything that fits???
I have a feeling it's an NPT thread, which is next to impossible to find in the Czech Republic.  Garrett likes to use NPT fittings on their T3 / T4 turbos, but we know for sure it's not a 1/8"NPT-27.


Do you even have the turbo?
YES HE DOES.  What kinda stupid question is that?
You think he's doing this for someone else???

You know, that's a legit question.
If people would actually follow your recommendation, we would cut down the numbers of questions on this forum by at least HALF.

It's funny you're all ragging on hIGGI when you're the one asking about CO2, N2(?) injection cooling for your intercooler...

First off, you’re a ***** Ted!…
J/K you are a great asset to this forum and I know its easy to get people confused on here. I was helping that guy with his thermo, I thought it was a dumb idea personally I love my AC and wouldn’t give it up for some crackpot idea that would have been done already if it had proved worthwhile.

pretty sure its not a NTP, it has no taper and it is a flared compression fitting. And the thread type matches up exactly with a 10 mm bolt so I am assuming it must be a metric thread oddly enough. The dia on my fitting is right at 11mm and the thread spacing/pitch is right at 1mm. Pluss you will need to convert to –4 to really do anything with it anyway unless you some special fittings I haven’t found, this would be your best bet http://www.atpturbo.com/Merchant2/m...tegory_Code=ACS unless you want to talk to aspec.

The kind of question that finds out why hasn’t he just threaded something in there to find out what it is for himself rather than sit at a forum and have someone else do it for him.I mean Im lazy, but damn dude pull your *** out of that chair

I have turbo and spent last 3 weeks finding out which bolt will fit in that thread, already wasted money on bolts with odd threads which were supposed to be right. As u probably know there is bunch of thread pitches and sizes which will be ALMOST right but not exactly (u could screw it up).

I am asking for simply reason, why discover America again when it was already discovered??? U think everybody should invent his own stuff when its easier to just ask simple question to those who are already there?

And of course any info stored here in thread like this could help someone else next time. Guess its not what u are posting for. Oh well....

O.K.


Try this http://www.atpturbo.com/root/navigation/contactus.php

Like I said earlier, they sell the fitting. They also sell the turbo. I was in your shoes not long ago.
