The SS lines are from specialtyZ and I am not running the restrictor that's required for BB turbos. I checked with Greg before purchasing them. If I could do it again I would stick with OEM oil feed lines. The SS lines required a bit of extra work that wasn't necessary for OEM turbos. At least I have them for the next set of turbos I'll be putting on in the future.
I set the piston ring gap at .017 for the top ring and .019 for the second ring.
