somewhat confused???
 

i was wondering where my oil feed is and my oil drain is on my turbo.
im guessing that the small hole with the threads is the oil feed. and the big hole one is the oil drain, but what also gets me that the big hole is the oil feed because ive seen adapters that connect like that. the little one has threads to stick a smaller line? any help would be appreciated...this turbo is pwning me. thanks in advance.
here's the pics (oh, and the turbo is a gt35 journal bearing!)

Are there 2 holes or 4?

there are 4 but i know the other 2 are the water lines, its just those 2 stumping me, but i might return this ebay crud due to being really afraid of a 250 piece of metal

I am not 100% sure, but if I remember correctly the threaded side is the oil inlet side.

hope your right because theres a video on youtube with the same turbo but that big hole is where his oil feed goes, but funny part is oil and water was leaking, maybe he didnt wrong and screwed it up on his own, but i will be making a build thread, starting tomorrow. i already got the intercooler on.. check the video out, its the exact same turbo but the oil feed is the other

I used to work for caterpiler, the threaded hole was the oil inlet hole on those turbos, but those were also 14 liter inline 6s.

hehehe, well those caterpillars have 12 liters more on me...lol
well hoperfully all goes well, should i use restrictor, so many peeps say yes and no, volume restrictor? wtf does that go/ i want to make a real good build thread showing what this ebay turbo can do or last, will keep updated constantly. but thanks for the help.

looks to me like the lil hole is the oil feed, and the other is the return, ive never seen a setup like that, and yes i would use a restrictor, but as in how you would use one i have no idea, one way to restrict oil is use the same thing i did for temporary oil line, was copper tubing for gauges, that way ur not flowing as much oil as u would with a steel braided line, thats just my 2 cents, i dont have that many miles on my setup but my ebay turbo is doing fine, and so are all the other peoples that i kno that have them

the side that has the threaded holes is the oil return requires you to have a flange to fit flush with that and a gasket it...and the other side that has threads and a flar fitting type is the oil feed...all that you can get from tunnertoys.com or w/e good guys thats where i got my kit...flawless

As a few others have said, the little hole is the inlet, the big hole is the outlet.
