AN line size for the ATS turbo kit

[phazertwo]

Anyone know what size the oil feed line is on the ATS 093 turbo??

I am thinking AN 4 or AN 5. I am just guessing based off of the 1/8 npt fitting its feeding from and into...

I don't know about that system. My 088 ats had a 1/4" steel line to begin with which works out to a -4 (1/4"=4/16) I ran a -6 on mine for the heck of it, but that's really a 3/8 line which is a bit of overkill, but later when I added a cooler line tapped into that circuit it worked out rather nicely because the size worked out well for the volume

My current line is an-4 and I am trying to decied if that is enough. Since I have the factory turbo, I am going to run an oil pressure gauge with the sending unit at the turbo so I know for sure when it has pressure.
