Can anybody please help me identify or tell me what these are for?
Are they necessary for full-none sequential twins?
And what size rubber caps are needed to cap off the system?
Refer to this website for sizes. (mcmaster.com/#epdm-rubber-caps/=wrlqvk)

Just installed stock twins, Pineapple pulley Kit and i'm not 100% if I've finished correctly.
Thank you so much for taking your time to help.


^^ I installed an aftermarket elbow, the elbow does not have a bung like the OEM does. now I have a hose (of uknown diameter) just floating around shooting oil into the engine bay. where am I to route this hose?






green:

 

Have you referenced the diagrams in this thread for non sequential?

https://www.rx7club.com/3rd-generati...-turbo-749702/

I ordered caps from there as well, can't remember what size, I'll have to check, but I'm pretty sure I have about 20 left over.

 

okay.. well there goes Pink and Red.

the rest is still a mystery do me. thanks for your help.

red: solved goes to block.
green:
blue:
brown:
pink: solenoid valve pressure regulator
yellow:
orange:
purple: (note i have this blocked, is this okay?)

 

Has anyone printed up a poster-size version of the stock vacuum hose diagram? I am going to put one on the wall of my garage. Seriously.

 

That hose spewing oil is your AWS.



Did you remove the emissions and other "unnecessary" components from the car?

You should probably look into getting the block off kit from Banzai

FD3s RX-7 Block Off Plates

 

thank you!

Only one Left needs identification. Hose marked Green

 

I printed out a few copies on 11x17 paper. Very helpful.
Some people also get them laminated so they last a bit longer.
Definitely worth it if you stay with the stock setup. Once you go single, the vacuum lines are quite simplified.


I checked out the diagrams again and went and looked at my engine in the garage. That green one is what I've highlighted in yellow. As long as that has some new vacuum line in that section that you have green, the rest is hardline back to the engine.

 

Thank you so much. anything on the vacuum cap size?

 

I ended up getting the 5/32" PN 6448K74.

They are a little long, so I ended cutting them in half, but the diameter is spot on.

 

woah, turns out the shop is in my city lol. thanks for your help man!!! Did you run into any problems plugging up the system? Maybe something I should look out for?

 

It's not really that hard. Just take your time and keep the vacuum diagram handy.

Are you replacing all of the vacuum lines as well?

 

I'll take my time, yea I have new thick wall Vacuum lines coming in tonight.
Printed out OEM & full non-seq vac diagram in 11x17 paper at work.

If I cap em, it wont trigger a CEL unless i unplug the harness to any of the solenoid(s), right?

 

When I replaced my lines I had one clean diagram, and then one that I marked up. It makes the task a bit easier just focusing at one line at a time and crossing them off.

There's two options for the rats nest/solenoids.

1. Cap and leave plugged in
2. Cap, remove rats nest, install resistors.

Either option works, I just left mine plugged in and capped the ends.
