Installation of injen intake Options

[6strngs]

I feel kind of stupid asking this actually. But when trying to install it, I notice one hole, and two nipple things. (for lack of a better word ) now, there is a rubber hose that obviously connects to one of them, and the other sensor plugs into the hole. but I don't know what the other nipple thing is for... the intake came with a 6"-ish long rubber hose that fits over the nipple but I don't know where the other end of that hose is supposed to connect to...

forgive my n00b-ness

The hose that goes from the crank case to the intake tube is the most important. It preserves vaccum in that area. If you want to, you can get an oil catch reservor to go inbetween, and it will catch any water and such as it recirculates that air.

A link to what this actually looks like. In extreme turns such as autocrossing, these can actually be necessary, as cars like the 350Z have reported oil splash being sucked into the intake and run through the combustion cycle.

For practical purposes and the time being, run the hose from the crank case to the intake tube, and tie the other one somewhere out of the way to either be left there, or used when you pick up an oil catch tank.

do you have any pictures? is the hose from the crank case the one that comes from somewhere deep down and plugs onto the nipple thingy that's closer to the throttle body? if so, I've already got that one on...

[6strngs]

Okay, here's the deal, I found a picture of the injen intake posted by another member of this board. I drew some red arrows pointing to the hose I'm talking about. I see it connects onto the engine... but my car already has a hose there that connects near the throttle body... what would I do with that hose then?




EDIT: stupid bandwith limitations... here's the image again

yeah it is, sorry, but can you tell me where the hose connects? I mean, I see where it connects now, but on my car there already is a hose right there that connects near the throttle body.

[LewFX]

follow the picture! the bigger hose goes from valve to intake, take that hose already connecting and put the other end on the intake.

[Toyoca]

i think the intake in my ST has only the o2 sensor connected to it is that bad?!

[ZacMan1987]

oh snap. I see now. Mine only had 1 nipple on it.

Yeah. The one closer to the filter end of the intake should be attached to the crank case as pictured, and the one which goes way down towards the back of the block should be attached higher up, towards the TB end of the pipe.

Toyoca
And yeah, if you only have ur O2 sensor plugged in, I'd go ahead and attach the other hoses. A little vaccum is definitely not a bad thing.

[Toyoca]

theres another hose?

[LewFX]

theres 2 nipples and a sensor hole on the injen

There is no O2 sensor on any intake, o2 sensors are on the exhaust. st cias only have 1 hole for the air intake temperature sensor. gt intakes have a line that runs to vac also.

k i c. does it matter that the other hole on my intake is open? (its custom) should i close it?

[/quote]

yeah ya should. the reason theres a filter there is so that junk wont pulled into the intake manifold. having a hole kinda defeats the purpose

k. how do i close it lol

[6strngs]

theres 2 nipples and a sensor hole on the injen

exactly! so I plug the sensor into the hole, then I plug that rubber hose from one nipple to the crank case, and then the other hose that comes from inside somewhere connects to the other nipple... so the other hose that connects to the throttle body doesn't have anywhere else left to connect to on the intake...

[Toyoca]

dont mean to thread jack but anyone know what i can plug up the extra hole with

[LewFX]

there should not be an extra hole! unless u drilled a new one for no reason

[Toyoca]

there should not be an extra hole! unless u drilled a new one for no reason

or...i got a civic intake and modified it lol. so there is an extra hole. how should i plug it up? you think it damaged anything? i figure there shouldnt be too much suction there

easiest way would be to wrap it in duct-tape... but that looks very unprofessional, lol. I suppose if you wanted it to look great you could take it to a welding shop and have them cut out a same-size circle and weld it in for you. could be costly though.

[ZacMan1987]

Ah. Knowing that it was a civic intake would have helped. So yeah.

If you've plugged in your intake temp sensor

and

If you've plugged in your crank case vac tube

and

If you've plugged in the other hose that goes off into neverland.

and you still have extra holes, then yes. You should plug them.

Weld, cork, do whatever, but yes, definitely plug them.

[QuintinGT]

What is the part number for this? i bought an injen intake that i though was this one but it ended up being 6 inches long. if someone could help me out that would be great!


[/quote]

[LewFX]

part number for the intake.....IS2040

B = blue
R = red
P = polished
etc

[CheesyLobster]

i dont understand... you are asking what the part number for the vacume tube is? if so there is no part number, just go to any car store and buy 6 inches of vac tube for like a dollar.

[LewFX]

oooh if the vac tube they gave is too long then cut it and size it up

[pandakid]

[b]if your talking about this nipple thing i didn't know what it goes to 2. but i just put a breather.

Sorry i should have been more specific, I was talking about the whole thing not just the vacume tube. LewFX answered my question though, thanks

[6strngs]

my question still hasn't been answered... I'll get some pics tomorrow to give you a better understanding of what I'm talking about.

[6strngs]

ok, as you can see, I've got the tube on the intake now (taped off at the moment until someone can tell me where all these tubes go!) now, I know now where that tube is supposed to go, but as you can see, there is a tube already there that runs to the throttle body. so if I take that end of the tube off to put the tube from the intake there, then where does the other tube go?!?!?!

[LewFX]

LOL ^ WOOT FOR MS PAINT!

[LewFX]

photoshop cs2 never ms paint

lol even better lol looks like ms paint

[6strngs]

that's the part I already know! I'm talking about the other tube!

fix the valve hose to the intake nipple and we go from there...your current valve hose goes to the throttle for whatever reason, the intake hose is going where?

currently; the intake hose is just taped off until I could get a straight answer as to where the valve hose was supposed to go.

[LewFX]

you got an extra hose going on there, take one off and put the other from the valve to the intake. like the picture shows...follow the red line.

[Toyoca]

[b]if your talking about this nipple thing i didn't know what it goes to 2. but i just put a breather.

thats what i should plug up my extra hole with. thanks!

[LewFX]

[6strngs]

right, so, what I need to know is what plugs onto the gold colored nipple circled in red. from your pictures, neither of your cars have this so I'm really confused.

also, the tube connected to the valve (circled in purple) is extremely difficult to take off. it had a little metal fastener thing (circled in pink) that I pushed down the tube a few inches, and then I yanked as hard as I could on the tube and it didn't budge at all...

[LewFX]

wow, never seen a plug there before...you gotta use pliers and clamp the fastener part to release the death grip and it should slide off..

try putting the throttle nipple hose over that and the 2nd intake nipple.

I did use plyers to release the death grip, it still doesn't want to budge... it spins, but doesn't come off.

also, I already have that other hose coming from the block somewhere connected to the second nipple (like in your pic) so I don't have any more available nipples! any clues as to what that thing actually does though?

[LewFX]

i say get it plugged or a breather, but get the darn death grip off that hose and get it on the right nipple

[6strngs]

right, I finally got the valve hose off after employing a second set of hands (thanks mom!) and a flat head screwdriver. got it all set-up how it should be, and put some tape over that gold nipple coming from the throttle body. gonna get a breather for it eventually, but for now the tape works. the car started and ran fine for my half hour ride to band practice and back. actually felt alot smoother in accelleration. Thanks for the help!

[CheesyLobster]

it could be something on older gts only. in anycase, you are supposed to have that line hooked up to a vacuum. you can either T that line going to your tb, or you can try to find another spot on your valve cover that is currently plugged off, and plug the intake line into that.

i noticed that chanhs old throttle has that same nipple, i didt pay attention as to what hose went to it.

[6strngs]

alright, I finally went down to a local parts store, picked up some emissions tube, which he gave to me for free, sweet. they didn't have any kind of T-joint, so I went to another store, they had this one, so I got it... $4.99... jeez, now you know why I like the other store. anyway, came home and finally got it all together, so here's some pics:




Thanks for all your help guys.

[WALKER]

Hey sorry for bringing this thread back to life, but I have some questions regarding this topic. Sorry I don't have any pictures to post yet from my own car.

I looked at my setup last night and I have that same goofy setup. I have a '95 GTS. not sure if that is why. Anyways, my question regarding this matter is should I change it around and make a T for my setup as well (like the picture below)?



What are the pros/cons with the way it is setup (in picture below)?



Can people post pictures of what their intakes look like stock (if there are any out there)? I bought my car with an aftermarket intake already on the car (it is cheap and ugly...homemade that needs to be changed), but my car does have the hose connected from throttle body across like second picture above.

Anybody else have an earlier model that is setup with the hose off the throttle body? Can we determine if it was year/model specific?

[6strngs]

I'd say, definitely put a hose from the intake to the valve cover. I felt a difference (however subtle), but after T-ing off to go to the throttle body didn't notice anything. I didn't, and still don't know what that nipple on the throttle body does, but I made sure it got it's vacuum just to be sure. it wasn't expensive, so why not? just go run down to your local auto parts store, ask for like 2 feet of emission hose (that's what I got), and try to find something to T it off with, something in the accessories department. and cut the emission hose into proper lengths and use the T and you're good to go!

[WALKER]

I just might have to try that. Have you noticed any change in fuel economy at all? Any negative impacts yet?

Anybody else have opinions? Any pictures of stock setups?

if anything, fuel economy has only gotten better. not too noticably though. I get about 23 mpg in the city, and like 30-ish on the highway. The only thing I've noticed, is that occasionally when starting my car, the revs will just drop all the way until the car dies. but usually revving the engine for a second or two cures that and it'll run fine the rest of the trip. of course, from what I've seen this is a common problem with the 6gc, and I don't think the intake has anything to do with it, cause it even did that once or twice when I had the stock intake.
