Noobed out CA18 intake hoses

[garagejunk8993]

Ive searched. And the most pic heavy thread with very good diagrams was for a FWD CA. Im just finishing up a build and cant seem to find out where these connect to. https://uploads.tapatalk-cdn.com/20170626/247d57b2d8b91d80fd742c4449f9f71e.jpghttps://uploads.tapatalk-cdn.com/20170626/4b0d4be9eea1a3a432a6a40a6fea2f54.jpg


And last time i checked this wasnt found on the CA? But i could be wrong. https://uploads.tapatalk-cdn.com/20170626/c6b448b54a1101f159e7031d1ff0383c.jpg




Thanks in advance, dawgs.

That valve thingy (can't remember what it does) is used on the CA. The hose from the IACV can be routed through the intake manifold runners and goes to the port on the cold side of the intercooler piping. There is also T that is supposed to be in that same line that goes to the valve and then from there to the first port you have pictured.

Hopefully that makes sense, I'm too lazy to take and upload pictures lol.

If anyone does have pics though that would be pretty sick. Thanks

that last picture looks like the cold start valve thing that usually lives under the throttle butterfly. ive ran without them before with no real issues and im in England where its always cold.

I remember them being on my KA's but i cant seem to find the mounting holes for this one. Ill check under the manifold today

I sent you a PM but I figured I would post this info here as well in case this thread comes up in someones search in the future. Here's how the intake manifold vacuum hoses are routed:

Comes out of intake manifold and goes to front of valve:

Goes from back of the valve to T fitting:

Front facing hose from T fitting goes to the coldside of the intercooler:

Rear facing hose from the T goes to the metal pipe that runs through the intake manifold and then there's a hose from the other end of the metal pipe that connects to the IACV. I think you're missing the pipe but it just serves as a bridge so its not really necessary. You can just run one continuous vacuum hose from the rear of the T through the intake manifold runners and up to the IACV to complete the system. I wasn't able to grab pictures of where it joins up with the IACV since my strut bar is in the way but you can see it in the pictures taken by the OP.

Also here's a picture of my vacuum setup with butterflies, I have one 3 lines total, one from the intake manifold to a T that goes to the butterfly valve and FPR. With this setup the butterflies open up the more you depress the throttle which isn't ideal but works ok and maintains most of their functionality. You're engine looks like the butterflies have been removed though, so all you would need is a line from the intake manifold to the FPR.
