I have a digital FSM that I got off the FAQ page and a Hanes manual but both of them are eluding me on where the turbo oil feed line and coolant line attach.

It is an BNR S5 turbo on a S4 block, and it has been a while since I took the car apart so nothing is fresh in my mind. I see the oil return goes ruin under the OMP (it is too long so using SS lines), and the coolant line is right off the water pump housing.

Now what I have inferred is that the coolant feed line comes out of the LIM? I am assuming most people don't keep that? Also in the diagram it kind of shows a place to connect the threaded end of the oil feed line? What is it showing, because nothing is attached to the block there where it points.

Yes, the coolant feed comes out of the LIM. Most people seem to keep it, I modified mine to come out of the coolant nipple on the rear of the engine. If you do this though you have to take the LIM off and cap off the holes in the housings or make a block off plate.

you can use 20mm freeze plugs:
Rotor Housing Coolant Passage Plug

the oil feel comes out of the block with a banjo bolt. it connects to the top of the front cover right behind the crank angle sensor.

The oil feed line is two pieces. Need both

I see now where it goes with the banjo bolt I barley noticed it until I found a diagram in Mark Warner's "Street Rotary" book. Unfortunately I look all day and have not found that second piece of the banjo bolt -_-

Any ideas of what I would need to size wise to find something that'll work locally?

I shall order, still need the banjo bolt though. I was just hoping to make it work just to start the car, someone is coming over tomorrow to help me get my rebuild going. This was something I overlooked :\

email them, he knows what size the fitting is on that end, he'll probably know what thread pitch it is.

im actually in the process of doing all my oil lines as well. i'm using a 12x1.5 to -4an adapter on the block for the oil feed and using an fittings and hose to replace all the stock stuff since the original feed is part of the rats nest

What about the need for oil restriction in the feed line?

I read somewhere on here the stock turbos have a built in oil restrictor but I also went with an undrilled flange for the the turbo
