First post of thread.

 

I was told from othermember it was 18x1.5 size to -10 AN? Can someone who it's good friend with Chuck or Steve Khan call and find out what size it's really is? I am planning to do the mocal twin oil cooler setup and I need to start gathering the parts and my biggest problems is with the fiiting, and everybody have a different size when this question comes up? khris

 

Khris, I was asking about the oil feed/outlet that comes out of the front iron, not the front cover. The one you are talking/thinking about is the one on the front cover.

 

14mm x 1.5 then the AN size line your connecting it to...

 

Here is my setup. The trick looking banjo to -3AN fitting was special order from Germany :p

 

special order :P .. ill stick to the adapter fitting. thanks for the info guys.

 

Bumping this one up for the great info provided by my old buddy CCarlisi

 

Keep in mind, some of these fittings are too long for the iron. I had to grind off about a thread and a half off the one I ordered.

 

I put together a table when i had the motor out last, about halfway down this page showing all the thread sizes for oil and water around the turbo:

Project Part 7 - Engine Build, Megasquirt, SDR manifold, rack and pinion steering

Scroll down to the heading "Rerouting the Turbo water and oil". The engine is S5 FC, FD housings, and S5 FC turbo. The pictures should show the context of how it goes together.
