I'm replacing my rear turbo oil lines right now as well. I went with the Dorman lines from Rock auto. At 145,000 miles I wasn't concerned with getting another 100,000+ miles out of a northern car with oem parts. Hopefully I can get them replaced without taking the turbo out. I have a 2012. Parts are as follows.
Coolant lines
667-673
667-674
Oil supply
625-814
Oil return
625-816
