I am thinking of just putting the stock oil feed line hardpipe back in and adapting to the fitting on the end then to the turbo. So either I find out if this is a normal fitting I can attach to or I just cut the end off and weld a new AN fitting on. Anyone know?

 

I don't mean the banjo fitting side as I wasn't clear with that

 

Might be worth looking in the single turbo section. The turbo side of that pipe is kind of a weird fitting, I don't think you can really directly adapt to it. I think you have to cut that end off and use a pipe to AN fitting of some kind.

I ended up replacing the whole thing.

All you needed to do was get a male 14 x 1.5 to AN adaptor and avoid any braid chafe.

 

I thought about just doing the fitting straight into the block. This just seems like a nice solid way to run it just to the side of the block. Figured I might have to cut the end off to make something work. Was just curious if that end was at all common.
