What are these hoses and where do they go? I just installed a CXracing FMIC and i looked up on where these hoses go but it seems everyone has different set ups and mine looks different from what it was originally. So... help?? I'm lose as to where these vacuum hoses go. http://i.imgur.com/dud8mbD.jpg http://i.imgur.com/nqMCin7.jpg http://i.imgur.com/31m4mw3.jpg

First one is the recirc for the blow off valve.

Second is vacuum source for blow off valve

Third is boost source for manual boost controller.

Do NOT drive your car without hooking these up. It will idle crazy, compressor surge and over boost.

Sooo... where does each go? The left vacuum tube connects to....? the other end of the manual boost controller goes to...? Should I just block the tube for the intake?

Where at in Arizona are you? I'm in Phoenix and could lend you a hand.

Do you even have a blow off valve? On a cx you need a flange welded on. For the wastegate source I made my own tap/nipple for it.

I'm in Prescott, So i'm pretty far from you haha. I do have a BOV! Surprisingly, if you dig deep enough in cxracing website, you can find a kit with a flange with bov. Sooo... Where do these hoses go now?

First one books to the blow off vent valve.

Second is the vaccine source to the blow off valve

Third goes to the intercooler piping above the turbo where you'll have to make your own nipple. Pretty simple man lol

Okay thanks! Unfortunately I don't have a nipple for the manual boost controller.... Soo... guess I'm fucked for the time being...

Nah dude. I found one a home depo. Drilled a hole and literally bolted it on. It was insulated with rubber on both sides so it never leaked.

Get you one of these quick taps (http://www.tf-works.com/atp-quick-tap-fitting-for-boost-source-turbo/), its a lot easier than tapping the compressor for a source, just be sure to install it right to prevent leaks...

Also on the second pic u might want to put a hose clamp on the hose on the coldpipe. That will leak boost like crazy

Okay, so here's how i have it hooked up.
top left vacuum from throttle -> BOV
top right vacuum from throttle -> regulator T'ed with boost guage
wastegate -> boost controller -> hot pipe
I didn't connect the recirc for the BOV and my intake is fluttering...
help! I'm wondering if my BOV spring is on too hard

Looks good. Make sure the hose on the bov is connected to the top of it. If you want to connect the middle nipple of ur bov it goes to the lower port on the tb. Otherwise let the bov vent and cap the tb port off
