Okay, I removed my OMP and no longer need to use the lower nipple on each of the two solenoids (wg control & turbo precontrol solenoid) that used to run to the nipples on the fittings for the omp lines. So do I just cap off these nipples and continue to use the upper nipples for wg and turbo pre control, or do I even need to cap them off?

 

Um, you are mistaken.

the oil injectors on the rotor housings have vacuum lines that ultimately go to the black plastic elbow that bolts to the front compressor housing, this way they get filtered but unboosted air.

I have minimal experience with removing the OMP, I like to leave them on when at all possible.

I can tell you this though---if you remove your OMP you should NOT be messing around with your boost solenoids.

 

The line coming from the compressor elbow manifolds with the pc/wg dump lines before feeding to the OMP nozzles. They are the royal blue lines in this diagram:

You don't want to plug the bottom nipple on the solenoids or else they won't control boost.

I'm not sure why these are all plumbed together, but in any case yes you could leave those lines open on the wg/pc solenoids. However, by open I mean install a short length of hose with one of those filter baskets on them so that dirty air isn't getting sucked in and jamming the solenoids, or have them empty into some other part of the intake that has atmospheric pressure.

The other option, which I would do, is plug the lines leading from this manifold to the OMP nozzles.

 

I see why I was thinking what I was, I didn't pay close enough attention to the diagram.

This is the one I am using, but minus the OMP lines.

So with this setup I could just do what you are saying and run a filter for both lower nipples, correct?

 

just leaving everything plugged in but cap the nipple that had the vacuum going to the oil injectors.

 

^ that's the simplest thing to do.

What exactlt is a filter basket?

Is it the same filter that the MAP sensor uses? Could I use even something like a little lawn mower fuel filter or anything a parts house would carry, or would the flow rate of the wrong type of filter throw it off for some reason?

I kinda like the idea of just running a short amount of hose out the bottom nipples and then just filtering them.

 

Or are the basket filters the same filter as what a solenoid would have plugged into it?

 

I was referring to the filters that snap onto the solenoids.

Awesome, thanks man.

One last question(s)....those 2 nipples coming out of the y-pipe (one points up and the other points down I believe), the white one in the diagram I'm not sure what exactly it is going to, and then gold one it just disappears.

Does the gold one go into the the LIM first and then into the pressure chamber or does it go straight to the pressure chamber from the y-pipe?

And the white one, only nipple I can remember in that area is the nipple on the LIM that sits below the fuel rail, but I am using that for the fuel pressure regulator. I believe that when I bought the car that nipple on the y-pipe (the white one in the diagram) was just capped off and not used. Is this the correct way to have it?

 

gold one goes to the other side of the LIM. You can see the same color coming out of the manifold but nothing is plugged on the other side. it goes there. It is your boost source to put pressure in the pressure tank.

You are using the wrong one for the fuel pressure regulator. The white line is used for atomisation of the secondary injectors, i don't think it is a good place for the FPR. The nipple for the fpr is a little more by the back of the car, at the same height on the LIM. Or you can just use any nipple that is unused on the UIM but make sure you cap those that are unused.

 

I had a chance to look today so I had the white line correct and wasn't using it for the FPR like I thought I was, so that was good to go. There is a bigger nipple on the "front" side of the LIM, and a smaller one on the back side, I just didn't remember there being 2 nipples in that area.

I just didnt understand the disapearing/re-appearing gold line but I definitely do now.

Thanks to everyone.
