I am in the middle of my turbo install and am wanting to remove the air injection system as I have AEM EMS and it will be unnecessary. I have seen the topics on it and know where it is but is this (inside red square) part of the air injection system? I have seen many people that seem to remove all this and the one hose that runs from the stock intake into the valve cover is normally gone, replaced by a single small air filter. I purchased the small air filter but what do you do with everything else? What is it used for? I want to take the proper steps to ensure that everything is done right. I have found many pictures of turbo setups that are missing all the "junk" in the red square in the attached picture but I cannot find anything detailing what it is or the proper way to get rid of it! Any help would be greatly appreciated as I need this done soon...tuning is Friday! Thanks! Also, does 0.030" gap seem ok for NGK BRK8EIK plugs? I am running pfab ELTM, GT35R, AEM EMS, AEM water/meth injection, Bosch 1000 cc's, Walbro 255lph, single 3" exhuast, looking for 450-500hp on stock compression so I would assume about 14-16psi. Thanks again!

 

Nothing in the box is a part of the Air Injection System. The grey hose with the brass fitting below and to the right of the box (in front of the alternator) is the feed to the air injections system.

But what you are talking about is the larger of the metal pipes in the box. It is a breather hose from the valve cover to the intake pipe.

You can do one of two things with it. Either connect it to the SC/Turbos intake pipe (not charge pipe) as per this photo:


(my set up now has a shorter hose on it and a one way valve so as to induce a vacuum in the crank case)

Or put a small filter on it.

 

Dont know if you should really be turboing an s2000s if you cant even determine the correct parts in an s2000 engine bay

 

We all have to learn, he is just doing some on the job training.

 

Hmm I don't think I was clear enough in my original question...I know what and where the air injection system is. It is on the driver's side, and you must remove the bumper to get to the pump and the lines for it run up to just behind the throttle body. There is a DIY on the site for it. I am aware that the large gray hose I disconnected from the stock intake assembly supplies the air injection system. I also have already purchased the small air filter for the hose that goes into the valve cover, I just haven't installed it yet as the metal hoses just to the right of it are in the way. My question was what are the other metal hoses just below this hose for. I traced them and one seems to run to the back of the motor...into the solenoid valve that the air injection system supplies air to. I also have noticed that in most pictures all of the metal hoses are completely gone and there is only one hose in it's place, going from just below the "butterfly" for the throttle, into the intake manifold, as it is in the pic that AusS2000 posted just above. I just wanted to know how to properly remove these hoses, if it was ok to simply plug their fittings, if they will not be used since I have the EMS on it now...assuming that they are part of a system not used by the EMS that is (for example, air injection system). I have looked in the Honda manual but it is in .pdf with hundreds of pages and it's the version where there are no bookmarks so you have to simply sift through the pages one by one. Table of contents isn't much help since I don't know the name of the system that the hoses are a part of and when I looked at the intake they weren't present in the diagrams I found. Hope that is more specific!

Yes and No, part is for the coolant system and other vacuum lines are for the vacuum canister and a ???? sensor. Neither are needed for your application. Route a hose form the water pump to the intake and bypass the IAC motor and TB.

I have seen many people that seem to remove all this and the one hose that runs from the stock intake into the valve cover is normally gone, replaced by a single small air filter. I purchased the small air filter but what do you do with everything else? What is it used for?
The factory intake is always under negative pressure so this is used to evacuate the valve cover and ensure not pressure build up in the crankcase. You can hook it to the suction pipe but you will suck in oil. I would just run the little filter.

See above

Do not regap those plugs

I am running pfab ELTM, GT35R, AEM EMS, AEM water/meth injection, Bosch 1000 cc's, Walbro 255lph, single 3" exhuast, looking for 450-500hp on stock compression so I would assume about 14-16psi.
Good luck

 

Awesome thanks! Hopefully that will be the end of my unexpected questions...I've been researching and setting up for this install for six months...that was just something I had overlooked.

 

PM or email me if I can help I definatly will.

 

Sure you can help! When can you come? I pay in twelve packs of your favorite beer. But seriously, thanks, I have most of my bases covered but I may take you up on that. No one around where I live knows jack about turbo installs...much less the S...although I've heard one guy around here has a turbo S...have yet to meet him. Thanks again!

 

Yeah, those other thin lines are vacuum lines. They attach to a hard pipe that runs the length of the intake manifold and connects to the IM at the rear. You can remove the hard pipe and connect your BOV and boost sensor to these ports on the IM.
