ive searched and searched, didnt find what i was looking for.
im throwing on garrett turbo. i need to know what size oil lines i should be using, also what size fitting i use for the return line on the front cover . and the size fitting i should use for feed line.

 

Oil supply line - smallest thing you can get - usually -3 or -4, smaller the better.
Oil return line - use the biggest thing you can get - typically -10 or -12, but I don't like to go any smaller than -12 if possible, larger the better.

The "fitting" on the front cover in not threaded.
I've seen people tap the front cover to install an AN adapter.

I *think* the oil supply line banjo bolt size is M14 x 1.5, but don't quote me on that.
