As the title states I'm requesting oil feed setup pics and info about differnt oil setups. The more info the better im doing this because i keep blowing seals in turbos, and want to make my lines stainless. Btw the turbo im running is a holset hx35 which looks like I need another one.

I am running the stock drain and a -6an feed line (EARLS) with a restrictor that's sold on eBay for journal bearing turbos, its marketed for a DSM but its the same thing. Also about rebuilding the holset, its really easy, D/L the manual from their website and read it then get the kit and do it. I got my kit from Penn Diesel for around $80 and its a genuine holset kit not a knock off. Just make sure to line everything up with scribe marks and don't bend the exhaust seal ring (I bent it trying to get it in and it sucks becuase its like a 3 dollar part that no one stocks)

Thanks that's the stuff I'm looking for, for rebuilding I don't want to rebuild it cause its not a real holset I found out after I bought it. I was waiting for it to blow to buy a real one. But now I wanna see what most of the rb community is running so I don't blow the next one.

chances are its not blown but being over oiled.
what size feed line are you running to the turbo?
im willing to bet it needs a restirctor.

I second that. Thanks again for your help on sizing mine Carl. Previously, mine would smoke a little while sitting at a stop light. It has been running flawlessly since. :cool:
