OMP and Single Turbo?

Where did everyone connect the vacumn lines off the top of the oil injectors to once they went single? I know some of you simply got rid of the OMP and all that and just run premix, but for those of you that still have your OMP, if you could, that would be great.

Thanks,
Scott

A simple solution if you wanted to avoid all the vaccum lines, would be to call Atkins Rotary and ask about the banjo bolts that replace the stock injectors. With them there is no need for the vaccum lines, yet would work the same. They were like $10 for 4, and since you have an FD it would be like $5. That's my suggestion, but I also don't know what I'm talking about.

You made your own intake? What does that have to do with the oil injectors?

I know they need a vacumn source at all times, no boost, I believe. So would a one way check valve work and just hook it up to a UIM nipple?

sorry - guess i skipped a few steps in what i was trying to say

you need to provide them with vacuum, so plumb it into the intake side of your turbo (which sees increasing vacuum with rpms/boost)

what i was trying to say is that if you get creative with some simple parts from home depot it is very easy to construct something like this.....that is what i did.

is that clear now lane change??

btw - there were a few threads a while back discussing the oil injectors and how they actually work. when deciding whether you personally want to cap them off, route them to the manifold with a check valve, or supply them always with vacuum, i would suggest reading through what was written there first.
