i cant find a straght yes or no answer, and i know that there aint a straght answer so all i want to know is if this is a good feed/drain line for my holset.....

feed:EXTREME PSI : Your #1 Source for In Stock Performance Parts

drain:EXTREME PSI : Your #1 Source for In Stock Performance Parts

and is i still need a oil restrictor , would this work: EXTREME PSI : Your #1 Source for In Stock Performance Parts

Ingot the same feed i'll be runnin with no restrictor but in going to test my oil pressure at the feed source, the drain needs to be -12 to be closest
Possible to holsets drain specs (19mm ID)

Feed, sure- drain is too small according to Holset but has worked well for some. You may or may not need a restrictor based on your oil pressure and the turbo's ability to drain properly, and none of us can tell you what your oil pressure is.
