there are a few things i need to know where they go and what they do! I had a freind help me with taking the engine out and didn't label everything, so now i have things where i don't know where they go any help that you guy'd could help me with would be great!

Here it goes the first one;
i do not know where this goes or what it does!


i know where this goes but i want to know what does it do can i remove it? if not then what is it's purose!


This one is on the lower intake and it pump coolant but to where! where does it pump the cooland to?


this is on the upper intake i need to know what it does and can it be removed?


Thank you all in advance!

 

tho part in pic three is the cold start thing it can be removed and blocked off. you don't need it and it harms the engine when it activates.

Pic four is the BAC valve I am pretty sure it can not be removed it adjusts the idle at differend loads.

 

Picture 1 hurts my eyes.

Picture 2 is the air supply valve .. it helps with hot starts, and engine load draws like the power steering. Keep it.

Picture 3 Pumps a almost pure miture of antifreeze into the upper manifold for cold starts in really cold climates, keep it if its really damn cold where you live, there should be a return resivoir for the antifreeze mixture. Otherwise you can pull it off if it's not that cold where you are, I removed mine, but I live in CA

Picture 4 is the BAC Bypass Air Control valve. It helps steady your idel, and help alot with the idle when the AC is on .. its not neccisary but I kept mine ... alot of mixed opinions on weather to keep them or not .. but I think it improves your idle, under loads especially.

well then maybe i should also mention that i removed the vacum spider and all sylnoids! and all! the BAC connects to what exactly. as the metal rack of vacume crap will be gone as well as the cylanoids!

 

Ok here it goes I also need to know where this goes and what it does!


also i need to know what this connects to so that i can reinstall it,



also i know the pic sux but it is the best i have does it resemble anything you guy's thinks goes anywhere?

I really need your help on these thanx guys

 

that crappy pic that hurts my eyes allmost looks like the thing that goes into the bottom drivers side of the rad, its probably not cuz I dont know why you would take it out to rebuild your engine

 

the thing in the last pic bolts onto the upper intake mani and the rubber hose connects to the intercooler, but off of the top of my head I can't remember what it is or what it does. sorry.

 

anybody else especially the little copper sensor can anybody tell me where it goes, also the red top thing?

 

Ok you ready?

First pic: It is the motor/block coolent temp sensor it goes in the rear side housing below the oil presure sensor.

Second pic: air bypass solenoid valve (part of the fast warm up system attaches to the upper intake manifold and hose goes to BAC)

Third Pic: Cold start valve this is where the” special juice" is pored into your motor to help you start faster if you live in super cold weather.

Forth Pic: that is the BAC Valve helps to regulate idle (like when you turn on your AC and put a load on the motor) and more fun smog stuff.

Fifth Pic: this is a S5 stock boost control it bolts to the bracket assembly on the drivers side. It sandwiches between that bracket the oil filler tube and a bolt

Have fun

 

you say that the fifth pic is of the s5 stock boost control The one with the red top? do I keep this or not! I have a T04RR turbo and well i heard that the stock one for upgraded turbos does not work well so do i just not reinstall this

 

With that set up you are going to need an aftermarket boost control. So no you don't need to re-install it

 

Ok thank u that answers almost all of my questions thanx alot! Rotary Racer!

 

I think you're going to want to install that red capped blue solenoid, partly as it is used to open your wastegate. If you go with an aftermarket boost controler, ignore that statement. I've seen people just bypass it and run the actuator straight from the turbo's boost, but that dramatically effects your boost pattern (partly because it opens the wastegate before the ECU normally would)

 

No prob

 

Sonic Rat can you do me a favour? I have heard from many people with large Turbos that this sylanoid accually does no good for a the larger amount of boost created! It makes sense to me that this sylanoid was designed to open and shut the WG for a factory turbo! so it would not work as well with a large Turbo!
Tell me i am right or wrong? that is just my understanding of it!

 

I cannot find where this goes still , does it go on the passenger side of the rear side housing or the drivers side of the side housing? It is one of the last few things before she gets going again?

Dude, you can get rid of all that bullshit.

The first pic goes under the oil pressure sending unit (round brass thing on the d. side below the oil filter). You MUST keep that, it runs the gauge on your dash for temp.

Everything else can go. You'll have to block off the BAC with a plate, or a lot of jb weld. IT is supposed to assist in idle fluctuation control and under load, but half the time they either under or over compensate, and theyre just general BS. The only time I'd keep it is if I were not doing the TB mod, as in removing the thermowax from it (and it's coolant lines, which can also be blocked off with caps).

Oh and leave that dumbass boost solenoid off too. IT works ok for a stock car, but not for moded. Be sure to cap the extra nipple on your stock turbo (if you have it still). IF you have a modded car, boost will rise on it's own, you dont need the damn solenoid.

 

where can i buy the cold idle assist block off plate . thanks alot please post a link thanks .

 

I made mine out of 1/8 steel cut with a hacksaw and then a bench grider and then a metal file to make it even more smooth then i polished it off!

 

I have just bought my first turbo gen 2 and am wondering how to run the vacuum lines to the boost controler which is now somewhat hooked to the by-pass valve. Not my work, bought it this way.
