I found the vacuum diagram under the 3rd gen FAQ but I don't understand where this one vacuum line goes on my new turbo because it doesn't have any vacuum fittings on it.
I have attached a picture with a yellow arrow pointing to the yellow line that I am referring to. Thanks for your help. Also if there is anything else that you could add that would be great!

 

I was also thinking while I was working. Where do I put the Blue hose from the oil injectors?

 

So I guess no one in the single turbo section has gone to a single turbo huh. Well thanks for not helping me again. What has become of this forum?

 

Attach the yellow line anywhere before the throttle body or lots of guys just cap off the nipple and delete the line, its the injector atomization port. Idle quality and afr's may suffer somewhat but as long as you are not running side feed 850's as primaries you should be able to get acceptable results with that line deleted. I premix and have never ran the omp or bothered to learn its plumbing but looking at the diagram it would appear it needs a pre TB source as well, you could have a couple nipples welded in your cold side ic piping, tap the outlet on the compressor cover for a fitting or use those quick tap fittings that install in the couplers, it is nice to have at least one vac fitting in that area for your wastegate side port if you find it creeping a bit past spring pressure which can happen if you plumb it off the uim.

 

Actually blue line is debated. Most people say that its fine to just vent it to atmosphere as well with a one way check valve facing the injectors. Others say it needs to go pre turbo in the intake line so it receives constant vacuum. Your choice.

 

The pink and green lines are not needed. Mazda got rid of the pink system in 95.

 

I had a collar made that I put between the intake of the turbo and the filter. I had 2 connectors welded into it. I use one of them for the oil injectors. The other I have running to a catch can and them to the oil filler neck. I removed the pcv valve. That way they both always have vacuum like the original setup. I'll look around for a pic...I think I may have posted here about 6-7 years ago.

 

here you go... pics in this thread.
