Hey guys, I'm almost done my install on this piece but I have a couple questions to make sure it works properly.

I can't quite figure out where all the vacum lines go, I know 2 of them go into the manifold but I can't figure out what to do with the rest of them.

Thats all I can think of at the moment, any advice is appreciated and pictures always make it easier!

There are two smaller lines, T them together and route them to the port on the rear of the manifold.

Ok I think I have all the hoses hooked up correctly and I did the idle relearn procedure but I still have an idle fluctuation from 2800 rpm to 1000 rpm. I took some pictures and a video.

Check for a vacuum leak. Spray some throttle body cleaner around the lower runners as well. I cracked mine somehow and thats what led to my idle issues after this swap.

Civic, whats kind of gains are you looking at from this manifold?

Arrrgg I can't find any cracks at all but it's still revving up to 3000. This is becoming super frustrating.
Gains for this mod are claimed to be about 15whp over stock

Idle calmed down to a rough 1500 and I threw a p0505 idle air control system. Also when I rev it responds quickly but there is about a 1.5 second delay after I let off the gas for the Rpms to decrease

Same code I was getting. I went through 3-4 IACVs before I said fuck it and blocked it off. Then when I was going to the big TB, thats when we noticed the crack.

Did you reuse any gaskets or get all new ones?

Nersh7

I reused the gasket between the manifold an lower runners, the other ones are new but just a temporary paper gasket

Did you inspect that gasket? Even though its metal, if it gets a crease its done.

Nersh7

I went over it pretty thoroughly and it looked fine

SPRAY carb cleaner at the gasket areas (lower, tb, im sensors) WHILE the car is running. See if you get the idle to change. If so you have a vacuum leak.
