Confusing vac diagram? Help. 87 T2. no emissions.
The Car: 1987 Mazda RX-7 Turbo II
The Motor: S4 w/ S5 Rotors, 2mm 2piece Atkins Apex Seals, emission block off plates, and a wild street port.
The Dilema: Ok I found this pic of the S4 turbo vacuum diagram with the emission block off plates, but I've ran into some issues. I made a video to show what I'm talking about.
The Video: http://www.youtube.com/watch?v=pirVoXrEtkg&fmt=22

**7:27AM Eastern time: The video is still processing in youtube so the HD version might not be available YET. Video was shot in 1080i HD with my Sony hdr-sr5. You can still watch the low quality version provided on the link, although I don't know if you'll be able to make out an of the footage. For sure by this afternoon the HD version should be up and running. I'll keep you posted on the video status.**

Bump! HD quality now available for the video. I also found out that on the oil injector air bleed line, that thing at the end is the "air tube connector" mazda part number N326-14-617. I'm not sure if it is special or needed though. All i know is that I don't have enough vacuum ports to connect my oil injectors to, so can I just use 3 vacuum tee's in series to get 4 nipples that i can route to my oil injectors or is that "air tube connector" like a fancy check valve or regulated tee? cuz otherwise this is my plan...
the top single nipple will go to the upper intake manifold nipple designated for the oil injection air bleed and the 4 white nipples will go to each oil injector. WILL THAT WORK?
Ah.... that would Explain my dilemma... I did not know I had an s5 intake manifold...hehe... could someone point me in the direction of the S5 Vacuum diagram with emission block off plates please.

ok there are 4 vacuum ports on the lower intake manifold
i'm not sure what the one on the lowest point is... guessing primary injector air bleed.
one at the mid point that sticks out at an angle: FPR vac line right?
Then the three ports at the highest position: 2 in the center, 1 coming out towards the firewall: guessing secondary injector air bleed right?
Is my assumptions correct? if so what vac/vent ports do I hook these up to?

Ok well there seems to be a lack of help here. LOL! anyhoo this is what I did. Since I have an S4 motor and T2 ECU i'm assuming that even if I have the S5 intake manifold, I still have to run the vac lines like the s4. so what I did was cap off what I believe is the secondary injectors bleed off lines and the rest I routed like the S4 w/o emissions.
pic provided.
and the 3 large vacuum nipples on the Upper intake manifold, I capped off the 2 near the throttle body and the one near the passenger side strut I routed to the line near the turbo.
Is this how its suppose to go?

Ok so then should I change my routing of vacuum lines to the S5 way. because right now I have it just like the picture posted 2 post above this one. I have an S4 motor, S5 internals, and an S5 intake, possibly an S5 turbo and manifold. but its ran off the s4 ecu, so shouldn't the vac lines be routed like the s4, so anything I don't use on the s5 intake I just cap off?

whats going on?

It does not matter how vacuum is routed. hell... you can tape a single vacuum source and use that for everything.
As far as using the s5 diagram, that is the one i would use. i would also get new lines, and get the pain stripped off all that damn stuff while your at it.
