I studied the single turbo installation. I weed out the rat's nest but I have a couple of vacuum hoses and nipples in the picture that I don't know where to connect or maybe to cap.
The #1 blue vacuum hose is currently connected to the oil filler neck.
The #2 blue vacuum hose is currently connected to the oil sensor (head/block).
Where do I put both ends ?

The #3 are bunch of nipples in the intake - can i cap this?
The #4 & #5 are two nipples at the top of intake - maybe i can use this for
boost gauge and the other for boost controller ????

I appreciate some feedback...thank you

 

#3 is just a vacuum passthrough to the other side. You can leave those open as they will not cause a boost leak.

You can use #4 and #5 for what you want to do, that is fine.

 

Thanks RENE --- maybe someone might have an answer to # 1 & 2.

 

Hi, check this out it might help. If you scroll down it shows the vacuum diagram for a single turbo.

All the vacuum diagrams you will ever need.

 

OK --- The #1 that I'm asking that is connected to the the oil cap should be capped in the diagram. (Single turbo installation diagram).

The #2 blue hose, which I can't find in the diagram. What is the name of this part? It's behind the 1st injector (front engine). I pointed it with a screw driver in the picture.
I have a vacuum hose and I don't know where to hook the end.

 

That is the OMP injector.

The hose going to it is just a vent and can be vented to the atmosphere. Some people put a small filter on the end to prevent debris from getting into and clogging the hose.

In the OE application that hose leads to the intake side of the primary turbo inlet tube due to emissions reasons.

 

tHANKS RENE --- i will do so, I appreciate the help.
Oh! my # 1 & #2 can also can be vented or hook up a small air filter?

 

you don't even know which part is which and you are doing this ?

 

Hey...i'm new to rotary -- for a rookie, i've done a lot

 

Not exactly on-topic, but is silicone hose is the best choice for that line running to the oil filler neck?
