Do you know what that would equate to in NPT?

It doesn't equate to anything in NPT. NPT threads are different than std. metric threads.

you want a straight 10 x 1.5 to -4an or you feel like a banjo bolt?

summit has em both

the straight -4an to 10mm x 1.5's part number is EAR-9919BFDERL

the banjo has 2 part numbers,
the bolt - EAR-977520ERL
the banjo fitting - EAR-997641ERL

See these two threads on the subject:
http://tinyurl.com/zjfxy
http://tinyurl.com/fgaue

I went down a similar path to Jayc72 in the first thread with the brake banjos. Very elegant. Unfortunately, -4 banjos in the 90* configuration are hard to come by, so I suggest using a -3 to -4 coupler just after.

http://www.summitracing.com/ is your friend. Go to "Online Store" and hit the plumbing section. More hose ends and adaptors than you can shake a wastegate rod at. You'll have to be somewhat creative in how you search, but if someone makes it, they've got it.

Often times, using the search engine near the top of these pages (on the blue bar) will produce a wealth of knowledge. For example, entering greddy oil lines turned up those two threads I linked to near the top, and a wealth of other data.

I've know I've personally been involved with at least half-a-dozen oil line threads in which I've posted direct links to the parts needed on Summit's site.

-3AN is closer to the stock greddy line than -4AN. Which is a bonus since that's more common in brake lines/fittings.

And you don't need a 90* fitting, I did it with a 90* built into the line. I have the 90* coming up to the turbo.

No ****? That's more or less what I'd consider the perfect solution. Any pix?

Sadly, the only M10x1.5 to -(x)AN adaptor that Summit sells is aluminum.

Ok, I'm impressed. Somehow I doubt I could weld something that small, keep it straight, and get good penetration, without burning a hole through the damn thing and filling the passage with slag.

All I gotta do is lathe a hole in the bolt. Hmmm. Gotta buy me a lathe first, though. <grin>

In all seriousness, I appreciate the offer, but I'll stick with the Banjo fitting for now- no sense changing what works. Just wish I'd have thought of your idea first.

Okay thanks for all the help guys, i really appreciate the help. I got one more question though. What fitting do I use on the Oil supply side of my Turbo? I have a Garret T25 off a DSM. I will be using a -4an Hose.

Thank You!
