Coolant comes in from the lower intake manifold, and drains into the bottom of the waterpump housing.

Oil comes into the turbo from a spot on the top, front of the engine behind the CAI, and drains into the front cover.

The lines are not flexible, just put them where they fit.

Rebuilding my S5 NA with S4/S5 NA/TII parts in preporation for the best possible NA Turbo install... don't have the lines, don't need the lines for a while. I just want to know where everything goes.

TII and N/A rotor housings differ in that TII housings have a water passage, which flows through the manifold and then through the turbo. You'll need to deal with that either by using a TII rotor housing and blocking the water passage off at the (TII) LIM, or using an N/A rotor housing and manifold and tapping for water later. IIRC, the TII front cover is the only one that has the fitting for the oil return, but both TII and N/A front housings have the oil feed fittings.

Where is the oil feed fitting on the N/A front cover??

As per the water feed/drain, I'm thinking to use the coolant passages that the BAC uses (rear housing to the waterpump). Just tap the inside of the nipples, and put a plug in them; then if/when I decide to throw a turbo on it, all I have to do is unplug the passages, and run some lines.
