Need a little help with the t-78 install

Ok fellas, After trying to figure out the english directions, I can't figure out what the 3 way "Y" connects to. I have the one metal pipe right below the oil line, but I don't know what the other two sides of the "Y" go to...
it appears one may go to the hose that comes off the oil cap neck...but where does the third go?
Here is a pic to show the hose I am talking about.
You can see I have caped off the water lines, and I have since put the one hose on the metal line with the "Y"...
What next?

So you connected that metal pipe to the rear oil return?
how did you connect the two?
I will take some pics today of what I have...
Did you use a grinder to shave your LIM? I assume you did it to fit the DP, I havn't tried fitment with that yet...
you don't happen to have a pic do you?


Also, why is the WG plumbed so far back? Is that the only place it would fit? It seems like you would want the WG as close to the engine (or turbo) as possible to release the pressure...

the best way to do it is to take your downpipe to a muffler shop and just bend the pipe. grinding is a sob. i will take some pics for you when i get home from school.

humm.. that is a good idea...would a shop be able to bend it without hurting the DP?
I will look into that...but first I will see how it fits

it will not fit unless you either get a JDM lim or you can bend it. any muffler shop will have a pipe press.

Is this correct?

My kit came with two of these...am I using it correctly?
I used the other flange for the front oil return...
but I only have one of the gaskets that fit these metal flanges, is that gasket supposed to go on the front or rear flange? I just reused the metal flange on the front gasket....



Also, here is the metal y I was talking about...What does this 'y' into?

Dave,
You need to put a block plate on the rear oil return line. You dont use the pieces shown in that pic.
That is used to replace the stock oil return pipe that is mounted to the front of the block. Give me a call.

Dave:

I hope this might be the answer you are looking for, here is what I did when I installed my HKS kit.. it had a similar Y-piece that you are showing there. The hose you have it attached to already looks like the PCV line that returns to the intake. I ran one silicone hose from each oil injector, T'd them into one line and then connected that hose to one side of that Y piece. The other side of the Y-piece I ran a hose back to a nipple on my intake pipe.

In stock form both the PCV and the oil injectors run back to the intake pre-turbo inlet. The PCV dumps it's gases back into the intake, and the oil injectors must like the vacuum.. not too sure on that one. In any event it works perfect for me. HTH.

Not really but I dont see a way or a reason to use the rear. The line would probably be touching the downpipe or the wastegate.

the guy that had the turbo before me used the rear so i attached it before i dropped the motor in. it doesnt touch anything but i was gonna change it if you said it would hurt something.

Ok here is some more info...
removed the studs from the LIM that interfere with the DP, I hooked up the DP and marked where I was hitting.
Using a hammer I put a slight dent in the DP and it now mounts onto the turbo without a problem...of course I havn't put that block off plate on that LIM yet...

I purchased an extra bung from NApa for $1.69 and had it welded onto the DP towards the end at a local muffler shop for $10...
I don't think I am going to plumb the WG into the DP...not yet anyway.

Once the other parts arrive, I will be able to put block off plates on, install my primary and secondary rails...and then figure out what fittings and hose I need for the fuel system. I will need to order the 3row Greddy, and decide if I want to go with a dual intank pump setup...
