Weird 16g bolt hole, underneath coolant line(searched, need help!)

[2GEEZEY]

Okay so im almost done with my 16g install I have a few questions. Yes i searched i cant find these answers so if someone could help that would be great.

Im running a stainless steel oil feed from the turbo to oil filter housing. is this okay? I heard it could be to much oil pressure.

I re-used the factory water line from my t25( bent it a litte)

HERES THE QUESTION!! There is a empty bolt hole underneath the coolant line on the turbo. Its facing the radiator( same as the coolant line banjo bolt)

But theres nothing there. what else goes here!?

I have both the coolant lines hooked up and the oil feed. HELP!!!!! I need this to start my car!

yeah its a ebay. Nevermind problem solved. My friend checked his and said nothing goes there. I have all my coolant lines done and oil feed, and return.

Is it okay to run a stainless steel oil feed line from the turbo to oil filter housing?

yes if your line has a restrictor. it should have a pinhole kind of deal. i got one from ebay.

Correct me if I'm wrong, but from my understanding, with journal bearing turbos i.e. ebay 16G, you don't need a resrictor. Journal Bearing turbos like as much oil as they can get.

Im pretty sure I dont have a restrictor. Its just the stainless steel line screwed right into the top of the turbo.

All turbos are only designed to handle a certain range of oil flow rates, oil pressures, and crankcase pressure. Causing any of these to be outside the designed range can cause oil seal leaks, lower turbine/mechanical efficiency (due to higher loses in the bearing), and bearing realiability issues.

I have no experience with running a 16G oil feed directly from the OFH, maybe member "jusmx141" can help you out. He is quite knowledgeable and probably has your answer.

If you have your balance shafts eliminated and your oil pressure relief hole not ported out then you might have too much oil pressure to the turbo. But if the balance shafts are still in then it should be fine. If you had a ball bearing turbo then a restrictor is a requirement but your oil pressure should be fine for the 16g.
