Talking Single turbo vacuum diagram

After extensive search, here is an attachment of:

single turbo vacuum diagram
oil catch can routing
boost controller and boost gauge hook up
boost control solenoid and/or WG solenoid hook up


All in one that might be helpful for those who are interested converting to single turbo and wanted to add some goodies or two.

This attachment is only for SINGLE TURBO with ALL emission and charcoal canister/PCV system removed with OMP system blocked off.

The routing of the oil catch can is actually what Damian suggested. I just basically put it down on paper =),

If I have made ANY mistakes, please feel free in correcting me and I will remap this diagram for the needs of us who are going for single turbo. Hope this can be helpful!

If any1 need me to add more bell and whistles to this diagram I can do that. Let me know so I can do some research and make this as easy to comprehend as possible. Many diagrams out there either is incomplete or is confusing as hell. Hope this help out the future single turbo owners out there!

Vacuum routing is always a debatable thing on at least a few issues, everyone should keep that in mind.

1) Your diagram caps off the atomization ports ("air bleeds") and the OMP injector air ports, all of which need to see fresh air (not manifold vacuum).

2) Those tees need to be BRASS, not plastic which could melt.

3) Mc-Master Carr sells high quality vacuum caps that will last much longer than the autozone stuff. http://www.mcmaster.com/ctlg/DisplCt...54344087987953 . part # 6448K74 are 5/32" caps, the most common size (aka 3.5mm)

4) The pressure source for the boost controller is debatable. Some have reported more boost stability by taking the pressure source from after the intercooler. Others run two different pressure sources, instead of one source with a tee. The side port source would come from before the intercooler, where the lack of a pressure drop will force the gate open earlier, while the solenoid (and thus the top port) pressure source comes from after the intercooler.

I understand. That's why I stated "with ALL emission and charcoal canister/PCV system removed with OMP system blocked off. " I should've elaborate more. This actually requires the "Premix". Hopefully this cleared things up. Thank you for pointing this out.

2) Those tees need to be BRASS, not plastic which could melt.
Word. I should've been more detail in this thread again =)

I agreed with you. That's why this is sort of an generic vacuum diagram for those that wanted things to be clarified and easy to read. If you want technical and exact locations of each bell a whistle that is up to the owner to decide. It is a reference for those who does not know where to start off =).

Guys, please input your information here like arghx. That way in the future, I can complete a much better, more detailed vacuum diagram for most of us.

Great response Arghx. Thank you.

It's a pleasure. I am actually looking for one myself before, but NON of them are complete and as detail. And I couldnt sleep that night (too much starbucks haha) Then I just started to gather information from many threads and put this one together myself.

Glad I can be of help =)

yeah I did a similar thing with LC1 wideband wiring. there were a bunch of threads but all the information was scattered and sometimes conflicting, so I compiled a complete wiring diagram based on what I read.

Why not just cap off the FRP? If you have an aftermarket FRP you can run it off the UIM. Instead of tapping into the Intercooler piping you could also run it from the UIM. I'm talking about the nipples that come out right after the elbow and throttle body. Just wanted to add that. Hope it makes some things easier. =]

Thank you for your thoughtful input. I totally forgotten that all of us(or at least most of us) will be using aftermarket FRP. Therefore you were 100% correct on this one.

As for the first nipple you were referring to, is it # 4 on the picture i've attached below? I just wanted to make sure before I fix the diagram =).

Thanks in advance.

I'm pretty sure that 4 works.

I think that all 4 of those nipples work, however, I'm not sure. Right now I've got my lines running off of all 4 of those though. I haven't actually tapped into my intercooler piping or anything.

The gas filter that's in the pressure sensor line. Where can I get that?

I am about to write up some full instructions on the single turbo conversion, i have compiled most of the info from various sites and just need to put it all together (minus all the dribble) so it is easily read and understood. Would you mind if I used your diagram as part of the instructions once it is finished??

No, I do not mind indeed I feel very pleased that people are liking my compilation and simplified form of this single turbo vacuum diagram. Just make sure you let me know once you get everything put together, I would like to see how yours came out =).

Any chance you have an updated diagram with the new input?

Thanks

No I havent mike. I've been way too busy dealing with insurance company (totaled my civic)and selling all my old parts in the FD for this single conversion. I wont have time until I am close to finishing up the engine bay.

No problem. Just wondering since I'm ready to start putting parts together. I'll just use the original diagram along with other's inputs.

For the boost source on the boost controller, could you just run it off of nipple 1,2, or 3 instead of before the intercooler?

So I am starting to plan my simplifying out as I all the intake and exhaust portions off for a single conversion. It seems that the first picture is still good except to use a separate line for the stock fpr on the UIM? I am running no emissions with everything blocked off including OMP. I am debating to cut all the extra nipples off the manifolds and filling the holes with a putty weld I used for the secondary plates. The excessive LIM has no nipples at all which would mean that the UIM would be the source for everything it seems.
