Weapon R intake manifold install question.
So today I decided to brave the frigid chicago winter weather and install the Weapon R Intake Manifold which I had bought used off of another FF.net member. Since I bought it used, the part didn't come with any instructions but it looked straight-forward enough so I felt I could go ahead without them. Everything went off without a hitch except one thing: There is a hose that previously connected to a "nipple" (hehehehe) at the bottom of the stock IM. On the Weapon R IM, there is no such "nipple" in the same section but a notably larger one at the bottom of the body of the main chamber of the IM. I am assuming that the hose connects to this nipple, however there are 2 problems with that:
To anyone who has this part: How do I get this to connect or what is actually supposed to connect here?
I will take pics when I get home to try to illustrate what it is I'm trying figure out.
1.) The hose is too short
2.) The hose is too narrow to fit

Bottom right
ghetto-edited some pics to show what it is I'm trying to accomplish.



last pic is a screenshot of a youtube video showing the intake manifold installed. The yellow arrows
point at the hose I need and the blue arrow shows the location of the nipple. If I need to take more
pictures to show what it is I need to do please let me know. This is the last piece of the puzzle for
me and I'd really like to get this finished
Thanks for any help you guys can give

Um, I am not sure how... but you seem to have a pre-production model. The pic below is a pre-production model. The green dot represents the nipple that should have been moved to a location between the runners on the bottom flange. If you manifold looks like this you are going to get a "Low EGR" light and your engine will run rich as a result.

I guess I am obligated to speak up here;
As one of the people who first got his hands on this manifold I found that the nipple for the EGR at the bottom end of the runners was missing. As a result I got a "low EGR" warning CEL.
I eventually had Weapon-R swap it for a new version which had the nipple at the correct location, however despite the fix I still have the same CEL to this day. What I don't know is if the old manifold damaged my EGR valve or if the port needs to be enlarged to match the long slot instead of just a nipple.
I have a big troubleshooting session planned for next spring... yah
Anyway, feel free to PM me for any info.
PS: here is a link to my dyno with the manifold and a couple thousand dollars of other aftermarket components.

Ya that is exactly what my IM looks like. What kind of tubing did you use and what size? Did you replace the tubing entirely or did the new tubing just slip over the old tubing? I ask because it would seem that the new tubing would be too large for the EGR nipple on the block. This little piece of rubber is the only thing that's missing!
I had assumed I'd be running lean with these bolt-ons I've got but as you say, with a low EGR light I'll be running rich. Hopefully I can get my A:F's fixed before too long though.
Do you have any type of piggyback unit like the AFC-Neo or something?

when I bought the item, it was described as the "final version".
https://www.fitfreak.net/forums/sale...-manifold.html
Description has been removed to indicate it has been sold but the title says it all. "final version"
In either case, I need that tubing. Anyone know what size I'll need and if I can just clamp it to the old EGR tubing? Or do I need to replace the tubing top to bottom?

r u sure it's a honda?
does it have an "H" for an emblem or ablue oval? LMFAO
why do u assume he's retarded?
there r no stupid questions, only stupid people

so anywho, I got it installed and working now along with my T1R intake 
The car definitely accelerates smoother though It seems as if I've lost some torque. I'm still fully stock as far as exhaust goes so maybe that'll help it out a bit once I start replacing parts there, though after reviewing sugarphreak's dyno sheets, I'm skeptical.
I'm happy with how it sounds and feels but I feel kind of empty at the same time lol. Not that I was expecting more than what I got, but the car just doesn't feel like my car anymore. I suppose that, in time, I'll grow used to it. In the meantime, I still love my fit.
And I did get the CEL
When I bought the manifold, I thought that this version was the one that wouldn't trigger the CEL. Anyone know how I can trick it?
and now for the pics:

Sugarphreak, where is the EGR nipple located on the new IM that Weapon*R sent you? I'm thinking about capping the nipple on the body and then cutting the one off of the OEM IM and welding it onto the new IM to see if that gets rid of my CEL.
it would be hard to cut the original egr nipple off the oem manifold cause it is cast into the aluminum part of the manifold. i would plug that nipple you are using now and drill a hole in the flange and weld a nipple there so you could hook the hose up to where the original egr valve was. i hope that made some sense to you.
If you have a look at your stock manifold on the lower flange (actually here is a pic) there is a long slot. It leads into a small square chamber and then into a nipple.

Ya that is exactly what my IM looks like. What kind of tubing did you use and what size? Did you replace the tubing entirely or did the new tubing just slip over the old tubing?

Even with the proper hookup to the EGR I have a theory that you need a chamber to match the stock manifold to really get rid of the CEL. I was thinking about pulling it off and having somebody weld on some aluminum tubing with a cap and a new nipple.

...The final version should have the WR logo embossed on it... not just a fancy sticker that comes with it.
...
I have the Greddy E-manage Ultimate for mine, without a computer of some kind your car will be running so lean you will no doubt be loosing power. When they first installed my manifold the guys at AJR were looking pretty worried about how badly the car was running until they tunned it.

I haven't really looked into the e-manage units all that much. How easy is it to tune with it? I'm assuming one would need a laptop to work it, huh? I've been heavily considering the Apex'i AFC-Neo because it's relatively inexpensive and offers a lot of tuning capabilities despite that. Obviously, I wouldn't be able to tune my car nearly as well on the AFC-Neo as I would on the E-manage unit, but there's always something bigger and better I guess
. I'm not even sure exactly how much tuning I could get done with the AFC. I've never tried altering my AFR's or maps or any of that stuff so I don't know exactly what I'd need.When do you think you'll be looking into this nipple-welding idea you've had? I'm very very very interested to see if that would work. Please keep me updated on that if you do pursue that.
I'm thinking I may take off the manifold for now, just until I can figure out a fix for the CEL and get my engine tuned. But for right now, the car sounds mean as fcuk from the inside lol. Every time I touch the gas I hear the suction and it's a pretty hot sound.

Honestly I would go back to the person you bought it from and ask for your money back considering they told you it was a final version and obviously wasn't. Would be much cheaper then having the old one modded.
E-manage Ultimate is good, but the Apexi is much cheaper and probably all you need.
Yeah it looks sweet and the suction sound is pretty unique. I still think it will perform under the right circumstances. I think with boost it will perform much better because it does allow a lot more air into the engine.
