cooling feed fitting size

[johng96gst]

After seaching I found one result, I'm looking for confirmation.
I'm finishing up my 6 bolt swap into a 96 gst, it is the cyclone if it matters, and I'm doing the plumbing now, when I relize I'm missing the fitting for the coolant feed. I had extra banjos off other turbos thinking it might be the same (12mm x 1.25- I think thats the right pitch). When I put it up in there it was to small. I saw in another thread that people where plugging with a 14mm x 1.5 x 1/2" bolt. I don't want to plug but is that the correct thread size, and do I get a banjo bolt and matching hard line for that. Or nipple out (like a hose barb) and rubber line.
Thank you.

14 x 1.5mm is the correct size.

Thank you for the quick answer, I've been beating up the refresh button hoping to get a answer tonight, so I can get it in the A.M.

Well I ordered the 14mm x 1.5 fitting and it is also to small. Is there a chance that this hard pipe might not be the correct one. Is there any models that have a larger than 14mm line for the coolant turbo feed line. Im completely lost.

I found this pick thanks to google.
This is the fitting in question.
