Ok, i just purchased a t3/t4 turbo used.. it has three holes in it and need to know how i run my oil lines to it. There is one small hole threaded(oil feed??) one big hole which i believe is for coolant??, and one hole that has a tube coming off of it whcih looks like the oil return.. Click this link and look at the pics of the turbo and can you tell me what they go to... Thanks..

Also, for the oil feed line, do i just get a fitting that screws into the middle hole or do i need the whole bracket assembly.. ****, better yet, anyone have any pics of their turbo hooked up so i can see the oil feed lines and return lines???

come on, someone has to have a basica simple diagram... Im pretty sure of what goes where but ive never done it so id like your opinions and pics if you have any...

this has been covered so many times before

 

Alright here are your answers, i believe...
Oil feed and oil return should be straight across from each other. the one with the tube sticking out is the oil return line. i am not sure about the water cooled section of the turbo, but shouldn't there be one more hole (4th) for the exiting of the coolant. Yes you need a fitting that will screw into that.
Here is the information for the oil feed line. https://honda-tech.com/zerothread?id=232145

 

I have to aggree with deepsi.... the tube that is bolted on is the oil return line which goes to the oil cooler or the oil pan..... Strait up from that tube should be another hole (smaller)..... that's the oil feed line and there should be two holes on the left and the right..... those should be the coolent feed and exit holes.... you hook those up to your cooling system..... make sure you have proper tubing that will be able to withstand the coolent temp... you also might need an electric external water pump.... to keep it cerculating.....
