Civic Adapter Carb Intake / Pics / Idle Problem With Filter

[Acid X]

EDIT: Project finished. Pics are up:

Alright. I know this has been asked millions of times, but i need to know for sure. I've already searched and havent been able to find as much info as i'd like to find.. But anywho. Does the 88-91 civic box fit without modification over the 86-89 accord carburetor? How do you attach it, and where do all the vaccuum hoses go? Not to mention, which vaccuum hoses go where, and what's a "hardline"? I seen in a thread something about plugging a hose at the hardline, and i have no idea what that means.

Also, this is the right box, right? (below)



I need all the info i can get by tomorrow! I'm going out to adam's (adams86lxi) tomorrow and purchasing a cold air intake from him and he's going to help me install it, but neither of us know exactly what to do..

lol thanks for the help a20a1! Ive never tutched one of these carbed 3geez before but i doubt we will have any problems. I just got to see it first.

[Acid X]

Haha. Thank you very much A20A1. You'z da best. lol.

[A20A1]

Yes you keep the air bleeds
Yes you keep the check valves

Plug the unused port on the check valve.


EDIT: you probably only need one air bleed.

you can toss the one with the check valve.

I'm sorry for not mentioning that, it took a while for me to gather my bearings.

lol, i remember mike helped me out for like a week to get my intake done.


ps. you can pass smog with number 8, 16, and 33 disconnected. lol

also, you will need to cut a bigger hole out of the civic airbox to fit your carb intake hole. drill 2 holes for the 10 mm nut and use those nuts and stock carb screne to hold downt he civic airbox.

[Acid X]

We skipped the screen. No need for it really. Anywho, its all installed and it looks awesome.. I had to do something that is really original to compensate for the height of the civic air box. I'll make another thread in the photo forum to show you.

Take a scoot on over to the photo forum to see pics. I got enough to probably make a very thorough how-to.

[A20A1]

Great...

CT it's not so much passing emissions, but keeping the vacuum tubes hooked up properly helps the vacuum controls operate the way they should.

Alriight, i got another addition to mah vehicle!

Adam doing some research:


Going to the store to get what we need!


Ripping it apart (know what i got yet?)


Some removed pieces:


Doing some test fitting (You HAVE to know now..)


Taking off the bumper (PITA):


No more bumper (or battery)!


That holes too small.. need to make it bigger!


Test fitting the piping...


Fitting the filter after removing the bumper...

[Acid X]

Drilled a hole to fit the intake air temperature sensor in there, screwed it into the pipe, and finished fitting it all...


We seem to have run into a bit of a snag! The civic box with its lid is too big to just fit normally over the carb! What do we do? ...An idea!


And the result is.... Can you guess?


Putting on the finishing touches...


Look at that sexy cover.. Omgoodness. Put some sealant on there as well as the screws.


And here she is, all finished and put back together!


I have a lot more pictures so i might make a how to thats picture heavy and explains a few things better than anything i could find on here.

[88accordalltheway]

cool, good job cory, maybe well do mine next, lol.

[Acid X]

Haha, its hard to do, kinda. Lots of custom fab-work.

[lostforawhile]

I ran into the same problem with the hood on mine. solution=

[A20A1]

.
Hook up the silencer to cut down on the noise, some people disable the AS valve but if you're keeping the stock carb controls it's best to keep the AS valve hooked up.

I dunno if the silencer is long enough to reach the port on the civic air box.

[adams86lxi]

lol, yea that intake was a bitch lol. But we got it done! So cory how did it drive home??? Is everything still working fine???

[keruhas184]

Does that temp sensor fit okay under the hood?

[Cheeseburger]

looking really sweet bro!

[Acid X]

It's a tight squeeze, but it works. I didnt think it was going to be on the top of the pipe when we drilled through the pipe, but it works. The AS-Valve i'm thinking about hooking up to the civic box, but i'm guessing i'll need to buy more pipe because i already know the old pipe wont reach.

Adam, it work's great dude. I noticed that once i got down here to where i live it ran alot better than up there. It really makes the car lose power at that elevation.. Haha. Though i'm still looking to gain some more low end out of this sucka.. Not sure what i can get it from though.

[Acid X]

I had this problem when i first got my car (LX), but anywho.. Whenever the car is under about 1100rpm's it idles really roughly and is very annoying. This was happening when i first got the car and still had everything stock, but fixed itself when i flipped the airbox lid. It was like it was choking for air and when i flipped the lid it was finally able to breathe. Needless to say it ran alot smoother.

Now that i bought and installed a cold air intake on my car it idles really rough, even a little rougher than before, and i'm guessing its because its trying to breathe but its not having much luck pulling air through that long CAI pipe. It's fine at higher RPMS and seems to run even better than it did.. At high RPMS that is.

So, could it just be that it's not able to pull enough air through that long tube under the small amount of RPMs and i need to open it up closer to the air box instead of only at the CAI end?

Or do i just need to adjust the idle, or even the air/fuel screw to tell the carb to put more air to the carb at low RPMS?

Any answers are appreciated!

Your carb may be running lean. Try taking the screw out all the way from the air jet controller (if it is not) and see if it helps. This is the thing that has lines A B C going into it. You changed the fuel filters recently? But anyway this can be a number of things, as it always is with our carbs.

[Acid X]

I havent personally changed the fuel filters, but they might have been changed. Why would i want to take the screw ALL the way out? Won't that be bad?

[A20A1]

you might want to check that the choke is working properly...

this is easy to see;
once the car is warmed up fully make sure the choke plate is open all the way.

[A20A1]

other then that check for vacuum leaks... vacuum leaks are more likely to show up with a restrictive intake installed.


Basicly the carb should run perfect without the need to flip the lid or remove it.
With the CAI the extra length does add some strain, but it shouldn't cause the car to run that bad.

Your problem existed before you did the intake... so more then likely it's not the intake.

nice innovation.
what did you have to do to reposition the battery?

[adams86lxi]

nice innovation.
what did you have to do to reposition the battery?

we just un bolted the tray and slid the tray about 2 inches or so over and used about 4 sheet metal screws threw the tray and the threw the old mounting spots. Works perfect. Ive had mine like this for over a year and i guaruntee it wont come lose.
