I know I need an oil restrictor. I know for a 2860rs I need one that's about .040". I am swapping out the OEM T25 on my completely stock CA18DET, which has an OEM oil restrictor which looks to be about .060". (See picture) The bolt in the picture closest to the OEM restrictor has a 14mm head (for size reference). I'm trying to find a restrictor for the turbo side oil feed so that I can retain the OEM line. OR at least figure out what size hole I need to drill in my home made restrictor so as not to starve the turbo of oil with two restrictors. I've searched for days and found nothing but AN fittings. I hate AN fittings since they do not share the same flare degree as OEM flared fittings. I do not wish to purchase AN fittings or anything having to do with them.
