Integra Airbox Conversion finished
Ok, I've been mulling this one over for a few weeks. About 2 months ago, the car ate my Injen (the fender and battery liners ate through the aluminum pipe) and I had to put the stock shitbox back in. I didn't want another CAI cuz I'm sure the same thing would have happened again, but the stock one just sucks. So I went looking around. Made an attempt to build my own that didn't turn out so well, but what it did do was make me think of this... can I put a different airbox in the car. Spend enough time on Honda-Tech looking at things and you'll get ideas of what might work. I thought I stood the best chance of getting something to fit and work well with the stock Integra box, so I found one on ebay for cheap and bought it. Got by the side throttle thing by re-using a piece from the top section of my Injen that was ok, and sure enough, they went right together. The stock tubing is rubber, which is pretty heat insulating too, so I shouldn't have to worry about that. Surprisingly, it looks like its supposed to be there. The only thing that says otherwise is the fact that the battery is gone (its in the trunk now), but other than that, it looks stock. Inside the airbox is a drop in Comptech/Uni filter, and other than the bracket I had to rig up, this was easy. Moving the battery, the part of this I had instructions for and came as a kit, was a pain in the ***. Nothing fits, nothing works the way its supposed to. Damn you Summit Racing. Anyways, here's what went on.... It works as is right now, it works surprisingly well.... by my very sensitive *** dyno, the car is quicker, more than that though, the response is much better... only problem, its LOUD. I need to work on that, but it shouldn't be too bad. This is just an intermediate step... ultimately, I want to get the full Comptech Icebox in there, but the stock box was a cheaper gamble incase it didn't work.
Battery in trunk-- This needs some work, nothing fits the way it should.
My Smurftastic filter
The whole intake arm
My temporary but pretty damn good bracket
In the car
I reused the stock battery shelf holes to bolt it down. The other side is bolted to the stock resonator boltdown on the clutch line bracket... you can see the inlet in the lower right corner.

Even the Optima gives off some sort of gas. H? Anyway, you can buy sealed battery boxes off of SummitRacing.com or JCWhitney.com.
Nice intake though! Almost looks stock. Just the tiny bit of Injen says otherwise. hehe...

I'm not terribly worried about it now. I know a few people who have done the trunk mount, everyone's still alive to talk about it. My sunroof is always open in the summer anyways, and I'm pretty sure there's some kind of pressure release vent in the trunk too. Air moves around. I suppose something like a gel cell or something would be best, but for now, this works. Need to make my own hold down... the dinky battery is too small for the box, which looks like it could hold 3 of them. I'll have it race worthy tomorrow. I'm just glad I have power, and the intake worked... a lot of time and frustration went into figuring out what to do about that. The computer is adjusting... I've never seen the revs climb so fast... this thing works!

looks nice and all, but what is so much better than stock about this? it is just a stock airbox with a metal pipe connecting it to the throttle body instead of a plastic one?
Would be sad if 8th Gen Civics had that set-up. But nice job indeed. I replied to your other thread, and to say the least, the chick didn't go to the extent you did.
Looks like you've got a positive gain from an intake... and it's almost stock. Sounds like something I wouldn't mind doing but I'm still debating about the battery being in the trunk... but not like I use my trunk for anything to begin with.

More pics, I did some improving/stiffening.
Reinforced the bracket with another mounting point

Lots of clearance down below, the Icebox should go right in.

Theres the battery wire, I ran it down the sideboards inside the car

With the cover off

No issues with the hood, it looks like it should be there.

A smaller inlet hole creates a stronger vaccum. The same amount of air gets in, but the larger pressure difference creates speed. Same amount of air, pulled in faster, gives you low end since it magnifies the engine vacuum. An open element is weaker than the car's vacuum since there's so much inlet area.

The only thing I migh have done differntly is that sincee the Injen was fubar, you could have used it to run from the TB to the pipe from the teg instead of the flex tubing. Just cut the pipe to where it fits where the flex tubing is and matches up with the teg pipe.

^^ Its 4 gauge, starts like it always did, charging system works fine, everything seems normal to me.
Thats what I did... all the black rubber stuff is Teg plumbing.
The other thing is that the Teg arm is conical, not cylindrical. One end is 2.5", the other end is almost 4. So there's no way to cut it in the middle and get the 2 to mate.

Battery taken care of now... it doesn't budge, thats a good thing.
Since the Summit kit comes with a Marine battery box, its fuggin huge. The dinky battery isn't nearly the size of the box, and the tie down that comes with the kit is pretty large. So rather than trying to bulk it up, I made my own tiedown from aluminum. A strap runs underneath the box, 2 5/16" bolts go through the box floor and hold the battery in place. The box itself is bolted through the trunk floor, its grounded to the bumper support, then the top is strapped closed. No wonder its NHRA approved.

at first glance it looked almost like some kind of dryer tubing

lol. good job.
get rid of that damn injen hose or at least twist it around so u can't see it. lol.
also, did the comptech foam filter came along with the teg stock box or did u purchase it? just wondering why'd u go with that instead of a multi-layer cotton ones like K&N.
I forgot which filters less but flows more. the foam or the cotton? I'm thinking its the foam that flows more filters less...

I bought the Comptech filter. To put in the Icebox, you supposedly need the Comptech Filter. I don't know if it has to do with the way it fits (the stock one is a cylinder, this is a cone), or if it was just to get you to buy more Comptech stuff, but they were the same price, so it was kind of a "pick one" situation.
The oil for it is different... its pretty tacky stuff, and you spray it inside and out, then massage it into the foam. According to the sheet that comes with it, the foam catches the big stuff, and the oil layer catches the small stuff. Like the cotton ones it uses a little dirt buildup to filter better. I wouldn't be surprised if a little extra crap got through, but I change my oil so often because of racing that I don't see it to be much of an issue.

you need to hide some of those loose wires you have under your hood...go buy yourself some split loom and zip ties! nice work tho, im impressed with the way it all turned out. the trunk does have a pretty large vent, so i wouldnt worry about the gases. as a matter of fact, the gases are more corrosive than anything, thats why honda put the battery in a container under the hood, because the gases flow in the direction of the power lines, so the first thing that would begin to corrode is your fuse box. youll be fine where your battery is now.

the other thing about the black plastic from the factory is it has a little more heat resistance than metal. that way the plastic tubing doesn't get as hot and won't heat up the air coming in. the plastic box covering the filter will also sheild a little from the filter from engine heat.
and open air elements automatically void warrenties. believe me, i know, i lost my 2000 Mustang GT thanks to an open air element setup.
