Where are people rerouting the intake pipe to throttle body hose?

Well I will take a second guess here. Maybe in the photo you are referencing, just maybe the guy put a nipple on the side you can’t see on the hard pipe and ran hose to the IAC so that it still performs as intended. Multiple people have tried to help you here and given you pretty darn good answers, OS took it a step further and spoke truth. So like already stated “anywhere between the MAF and the throttle
body”.

 

No I appreciate it, you and some other dudes have been helpful. The other guy has just been argumentative and kind of a dick. Yeah maybe the dude who's truck I posted has it hidden, who knows?

I think I'm just gonna make use of the factory nipple and last leg of the OEM intake

 

It would have been way more helpful for everyone else if you lead with the last picture you posted. By essentially obscuring your question, it made it difficult for others to understand why you were trying to do whatever it is you're doing. The picture answers that question, and you probably would have gotten more helpful responses overall.

 

my bad, I thought it was pretty clear - I have a stock nipple, I want to do what the guy in the second pic did, does anyone know how he did that?

 

Unless that specific guy from the image chimes in, nobody will know exactly what he did or how he did it.

Chances are all the hose connections are simply on the backside of the pipe out of sight.

With whatever custom pipe you make, you just have to put vacuum line connections somewhere on it between the MAF and TB like has been shared already. How you achieve that is up to you, could just drill a hole in the pipe and weld a nipple. If thats not an option, you're gonna have to get creative.

Heres a hardpipe with visible connections:
You can see theres one in the back going to a vacuum switch (not the red circle hose), could put them all on the back like that and it would look just like your op picture.

I think this guy posted because he was having with routing issues though so don't copy any hose routing from the image. Maybe read the thread and see if any of it applies to you.

You've got a completely custom setup- you need to do something custom. Figure out a way to add a nipple and connect the hose.

If I were having to approach this problem, and without knowing if you have access to any machining tools or skills, this is the most simple thing I could think of.

get something like this:


And then get a little chunk of something soft, nylon, delrin, etc... and make a washer that fits flush with the ID of the intake tube. done.



I would highly suggest looking mc master carr or the like to find the fittings.

If I were doing that myself, I would get a piece of delrin, drill and tap npt threads into it, and shape it to the ID of the tube, and use the inner piece as the nut as well. I would also add a little high temp something er other as a lock to make sure they stay in place and don't end up down stream in your TB/intake.

 

That's what I'm starting to think

Not a bad idea, I think if I'm gonna drill and tap anything it would be the throttle body itself, that way the whole intake could come on and off super easily and just be a single piece of pipe

I have a replacement airbox coming, the mounts and box are broken on mine and with the way its setup now it wouldn't fit quite in the factory mounting position anyway (that's the reason for this whole thing)

I think my plan is just to cut down the OEM part even more, and see if I can bead roll it.

Factory airbox and MAF housing --> reducer --> 2.75 45* pipe --> 2.75 coupler --> cut down OEM black pipe with IAC hose --> coupler --> throttle body

orrrr I drill and tap the throttle body and just have a single 45* intake pipe going from MAF housing to throttle body

 

I wouldn't touch the TB if I were you, and I think you need the line for the IAC to connect before the butterfly valve... replacing a throttle body is a lot more $$$ than a plastic intake tube.


this clip from that last pic shows a fitting on the back. It doesn't look like it's going to the right spot, which the poster mentioned, but the concept is at least viable.

 

Agreed, TB is a much spendier part, and it's cast, so it could decide to blow up when it meets a drill bit

looks like he has his routed to his PCV valve, but yeah the premise is the same

 

OS is O”Silver and he ain’t a dick. Helps plenty here and knows his stuff, speaks truth and sometimes plain about it. Just so you understand that. May just be that most hard piping is done to do resonator delete in some hp gain effort some think is not worthwhile. I mentioned resonator delete in first response you got, perfectly reasonable others thought that was goal here.

 

Maybe he just needs a new hat

 

Ah just forget I said a single thing. You’ll figure it out. Good luck.

 

Yes I am.....

.......sometimes it happens when you get old


Marvin

I am impressed........I have never seen such a set up....that is cool

reminds me of a Marvin Minsky's design.......


you are very unique.......dont let anybody tell you anything different...


......but seriously.....please dont ever work on my truck

 

Surely your messing with us

you still have the stock tube........with the elbow on the back??????????????????????????

Did Putin put you up to this........a new form of war

confuse the enemy

turn tacomas againt tundra's....

 

alright dude, since you seem to be basically retarded, I'll try and break it down for you.

That is my engine bay in the most recent pic, it is using a stockish intake setup.

That's why I posted a thread about "rerouting" a hose. I didn't ask about cold air setups, I didn't ask about deleting IAC hoses, I didn't ask about how much horsepower I would gain, I didn't ask about secret magic passages. What I wanted to do was take a stock style setup, and if possible replicate a setup I had seen on the internet, wondering if perhaps people had seen a setup like this. I was expecting answers anywhere from: "yeah I necked up a 1/4 throttle body hose to the 5/8 IAC and it worked fine" to "no, that picture isn't showing everything and it doesn't work"

Some other dudes essentially answered both those questions, and I am the wiser for it

Your first response was a bunch of random nonsense involving pretend HP gains, intake temps? and 100k maintenance
Your second response was showing off your cold air intake
Your third response was preaching about how cold air intakes aren't a good financial investment (kind of ironic)
Your fourth response was was informing me that with no IAC feed I would have a rough idle, I'm pretty aware of that, which is why I posted a thread about rerouting that tube, also it won't have a rough idle, it will die. There was also something here about sod houses and skateboards
Your fifth response was something about silicone being expensive?
Your sixth response was actually on point, and helpful
Your seventh response was showing off your cool blue hoses in your engine bay and implying I can't handle swapping hoses
Your eight response was admitting you're a dick, and more cheesedicking
Your ninth response was enlightenment realizing I have a stockish setup and am hoping to change it to something shown in the OP, crazy I know, almost like that's why I posted this thread. Also suggesting I'm Russia bad or something

I can't wait to see what the tenth response is. Either way I actually do appreciate the attempt at help, I realize the perception of noobs posting on the internet about cold air intakes can jade everyone on forums to try and stop stupidity. I'm also here for the shit talking and not mad about it, hopefully you aren't either, and if I'm ever in wherever you are I'd be down to have a beer and talk about how stupid your truck is and vice versa

 

I'm not mad at all.......I'm floored by your solution

I'm sure most everyone here jaw's dropped too

thanks for this post......your setup is quite unique.....didnt see that one coming

and sorry for the confusion......that sure looks like a cold air intake tube

pretty sure 100 out of a 100 here would use it for just that

of course they'd have to install a nipple of some sort to supply iac


you seem to be the one upset.......I'm not....I'm just little ole me

.....I didnt mean to be mean, or upset you




I found a better pic of how mine ties into the back of the intake tube



I really dont give a rats ass about how cool it looks.....
I've gone in and replaced almost everything replaceable ....
so might as well use good stuff when you do it.
......you dont want undetected leaks anywhere in this area.....old black tubing just hides cracks and decay...


If I was that other person......I'd do something about my gray primer body



It looks like my intake tube is way easier to remove than yours
....but, you beat me hands down in style and complexity
I'll save that in my archive....even your oil cap is bizarre.....I love it

these engines are very simple......you seem to be very complex....

 

Hahaha!
