gonna put -6 AN fittings in the turbos for new feed lines. need to know what threads they are for a H1C and a BHT3B. and if they need to be o-ring or not. thanks in advance
Little turbo should be a 12mm to 6AN or JIC unless you use the holset fitting then it is 5/8th flare to 6AN, big turbo is the same or a 14mm but I'd have to try it to be forsure.
