VACUUM MESS *Cluster FTuck* How Do I Get Her Hooked? A6/Z6/Venom
Im having trouble figuring out where ---- has to go with this mixmatched setup Ive got here
Car is a 88 Crx Si, hd a sohc zc in it before this motor and everything was mint.
Now Ive swapped over to a d16a6, internals are built, car has a venom intake manifold that was made for a D16z6, I retapped the throttle holes and am using a D16a6 JG 64mm t/b
Now with this intake manifold, its square, so it does not allow you to use the little vacumms port space ship looking thing ontop of the throttle body (held by 2 screws), Im sure it has a lot to do with vacuum but I dont know what
So this is what Im left with, heres some pics, if you wanna see something else please ask pics arent a problem.



i know the pics arent great, just random ones I have and can show what Im talking about. You can see what I have for vacuum ports left, Ive used one for the wastegate, one for the brake booster and I need one for my vacuum manifold (used for BOV and boost gauge) and I will only have one left *dont forget abuot the fuel pressure regulator)
---- this is a mess, i just wanna start this car
EDIT:
Heres some better pics of whats going on



Heres kinda what I sketched on a little diagram, just basic what i could draw quick and come post it here, I forget which one T-D into the 3 lines at the end like in the pic you see ontop of the intake manifold

Hope someone can help me

The vacuum "space ship" thing you speak of is actually supposed to be run off of intake vacuum. All it's for is to slow down the throttle plate as it closes to keep the idle from dropping too rapidly. Don't worry about it, just leave it off. Also don't forget the vacuum line going to the evap canister solenoid on the firewall. Usually runs in the same line that goes to the map sensor as well. Hope this helps...also check out the online pdf manuals posted at the top of this section. There's a crx manual you can download and check the vacuum lines from there.
I dont even know what the map sensor or evap canister looks like, thats why I know I need help
I just need to know what lines comes from where, goes to what, here to here,
This car was a total rebuild to turbo with tons of wiring upgading and everything
So I know Im gonna have problems upon startup, hopefully this wont be one
Hope you guys can help

Like i said...download the manauls posted above...takes a couple minutes, but they're the complete service manuals. The evap solenoid should have one line running from it to the evap canister that your big red braided hose runs to, and should have a vacuum source running into the bottom of the solenoid. The solenoid is usually T'd in line with the MAP sensor, which runs off the intake manifold.
*edit: Here...i'll make it easier for you...http://www.crxpower.net/~silverkorn/...hop_Manual.pdf Download that and read through the emissions section i believe.

Oh! There is a line coming from the firewall that is a braided red that connects to the top of the t/b, that one is done no problem same spot as before
Its these 4 vacuum lines that I dont know what to do with
I think the coolant lines on the bottom of the t/b might be fucked to

Ok here an overview of how its setup now, you cna see the one vacuum line from the map sensor to the top of the throttle body, the rest goes to that canister I dont know if its right but I dont remember changing anything, red hose to the fire wall, red hose to the throttle body and vacuum line goes to the top barb of the far right pot, is that right? or should that one vacuum line be disconnected entirely and left open?

Heres what the pots on the firewall look like you can see im only using the one to connect to the pcv canister the other 3 barbs are left open, do they stay open, capp them or do i do something different? I dont know
