Ok, I've got an S4 TII swap into an 88 vert about 90% done, trying to finish up the odds and ends before trying to fire her up.

Just to make sure, the hose from the top of the oil injectors (not the oil feed hose) is connected to vac/boost, after the TMIC?

Where is the best place to connect the FPR and brake booster to vac/boost?

There is a second nipple emerging from under/behind the water pump that isnt present on my NA engine, that wasnt hooked up when I got the TII engine. Where does this go?

Does anyone have pictures of the throttle linkage on a TII? The TII cable i got has the same connector on the engine side as the NA cable, yet the holder for it on the throttle is different.
Also, the throttle cable bracket is (i'm taking a guess here) screwed onto the UIM right near the throttle body? I'm adapting the NA bracket to work in this location, is this stock?

Thanks a lot for your help, Im trying to get a lot of this stuff resolved by the end of the weekend

What hose from the oil injectors? The vacuum lines that connect to the spider?

I'd hook the FPR to the same vac line as the pressure sensor. The brake booster goes on the massive nipple kind of on the under side of the UIM on the firewall side.

The t2 throttle cable just kinda wraps around the engine bay. I have mine bolted to the front engine hoist hook and zip tied to the upper coolant hose.

Yes, that is the stock location for the throttle cable bracket on the back of the UIM.

*****Just to make sure, the hose from the top of the oil injectors (not the oil feed hose) is connected to vac/boost, after the TMIC?*********

The line on top of the oil injectors goes to a Spider, just like your n/a did. Then the single large hose off the spider goes to the LARGE nipple on the back of the throttle body. There should be three and maybe four metal nipples one above the other back there. The large nipple feeds the oil injector spider.

The brake booster vacuum hose at the rear of the throttle body is located to the right of the four metal nipple just mentioned above. You need to find a hose with bends in it that will reach from there on the throttle body over to the right hand side where the n/a brake booster line exists. There''s other ways but that will do.

The FPR vacuum line can be connected to the ANGLED metal nipple on the upper intake manifold. It's the nipple just above the oil injectors on the manifold.

great, thanks a lot. Any ideas on the nipple sticking off the bottom of the water pump, behind the one that connects to the hose that goes to the bottom outlet on the rad?

HAILERS

Oh. That nipple. It sounds like the nipple for the Turbo water outlet, if I read you right.

The water outlet for the turbo is on the inboard/bottom side of the turbo. It's a metal line and ends just above the oil return line where the oil return line enters the front cover. Make sense?

Let's hope you bolted up the coolant return line before bolting the turbo to the manifold.

no, when I got the engine it was already bolted to the manifold, and that to the block. I only noticed this yesterday, after the engine is in the car and mostly connected. I hope this doesnt turn into a real pain in the ***... can I use a normal coolant hose for this, or does it get too hot for that?

Ok, i got pictures of the items in question. In the first one, the nipple is circled in green, and in blue is the hose that connects to the hard line running between the turbo and the engine. This hose is routed up around the LIM into the back of the waterpump, shown in picture 2. The other coolant hose goes directly into the LIM (but not into the runners themselves) in picture 3, in red. Is this an acceptable way for the coolant to be run? It seems to be bypassing the water pump for some reason. If so, should I just cap the other coolant nipple (green one)?

HAILERS

NO. The Blue line that is now attached to the back of the water pump housing should be going to the BAC. To be clear, there should be a hose going from the back of the water pump housing to the water fitting on the BAC.

The Green nipple is for the turbo water outlet.

The RED hose is right. It is feeding the turbo water. That's good.

there is no more BAC, emissions, rats nest etc... the previous owner of the engine ripped all that stuff off. In that case, is this correct? And thus, the blue hose has nothing to do with the turbo? In that case, the prev owner didnt put it back on. Fortunately, I do have a stock S4 turbo (the one on the car has a different cold-side) that I can compare with tho. So the tube circled in yellow is the turbo water outlet then? looks like i'll be removing the turbo then...

a bloody knuckle later and the turbo's off.... but it does have the turbo water outlet, and that's what the blue tube is attached to. So i guess that begs the question, where is the blue tube supposed to go? Normally its water pump to BAC, after BAC where does it connect to?


Edit:
upon second review of the FSM, it seems that the blue hose should connect to the green nipple, and the nipple that the blue hose is on now (on the back of the water pump) should be connected to a nipple on the rear housing, completely taking the manifolds out of the loop (since the BAC is gone)

Which brings yet another question... most diagrams of rats nest/emissions removal let the BAC live, why would you want to remove it? Is it the same from NA to turbo engines?

Well, I seem to have gotten it sorted out. One hose from nipple on the top of the rear iron to the back of the waterpump, one from the Turbo water outlet to the nipple behind/under the waterpump, and the vac lines hooked up correctly (with the exception of the BOV, which i dont have yet). Just need to put some stuff back together (fan, alternator, TMIC) and add fluids, and she should be ready for a test-start. Thanks for everyones help, this project would have been a lot harder without your wealth of knowledge.
