Alright guys, I am trying to install the Ultra Series Street IM, but I am stuck and don't know what to do.

First picture: I watched Skunk2's video on their Ultra Series installation and it's hard to tell which hose will hook up to the proper location. In their video, it shows the same as my picture, and I am not sure where that is suppose tp lead to.


Second Picture: You will see an opening next to the filter, as shown in Skunk2's video. I'm not sure where that is suppose to lead to.


Third Picture: Same, but with the plug. What happens if I plug it?

In the 3rd picture that needs to have a hose from the intake manifold plenum going to it. The idle air control motor needs to be able to bypass air into the intake manifold to control idle. You need to move one of the hose barbs from the plenum to the fitting on the IAC and run a hose between them. The plug is for where the hose barb was.

Now that you explained it, it makes a lot of sense now. Thanks for your help. I'll have to go to an automotive or hardware store to get another hose barb so I can fit it under the IACV.

So I just picked up this manifold and have been pretty disappointed that there are no instructions that came with the manifold or on their website or on youtube except for their comparison video. I have figured just about everything out except for bypassing the coolant.

The coolant comes in through the idle air control valve, would normally then go from there to the throttle body ( I have a blox 70mm that bypasses) then from throttle body to the intake manifold to be recirculated. With the new intake it has a blockoff where the coolant will normally go into the manifold so the coolant had to be recirculated at a different point. Before I Ghetto Rig a t-fitting somewhere I was wondering how everyone else bypassed the coolant

Thanks

block off the coolant going to the manifold. no need to loop it

That is what I am trying to do. But I think that it should be looped so there is coolant flow. I could put a vacuum cap on the coolant outlet of the IAC, but then coolant is just going to stop there and not circulate. I was thinking that it should leave the IAC and re-enter the cooling system somewhere else (It re-entered at the IM before)

Edit. I guess I got the flow backwards, coolant leaves the head and enters the throttle body, then the IAC, before renetering the system. I am looking to get coolant into the IAC then before it re-enters so I wont have problems with cold starts

I don't think blocking off the coolant to the manifold is a good idea. The manifold needs to cool. I have the Skunk2 Alpha TB. Here is how I did mine. (Looking at the Skunk2 Alpha TB) The nipple fitting beneath the throttle plate on the throttle body connects to a small hose (coolant) that runs to the engine. The next nipple fitting that is parallel to the one that has the coolant hose is connected to the IACV. The top fitting that is next to the MAP sensor is connected to the EVAP canister. I was told by Skunk2 that if you are running Hondata, then the EVAP will be eliminated. I am still running the stock P72 ecu, so I will be utilizing the EVAP canister for now until it is tuned. The next opening on the IACV is connected to the coolant pipe underneath the intake manifold. In my picture where you see the bottom opening next to the uni filter, that will be connected to the hose barb that my finger is pointing to. This will only help circulate the air to the intake manifold.

I hope this helps.

I figured it out. You have to bypass coolant in a sense to the intake manifold, the new one comes with one plug, and one barbed fitting, the coolant line from there goes right back into the thermostat. the second one that is now blocked would run a smaller diameter line from the Intake manifold, to the Throttle Body, then to IAC before going back into the thermostat. Since the smaller line was bocked, and my billett throttle body doesnt have coolant lines since there is no FITV, so basically what I needed was to take coolant from somewhere, run it to the IAC and let it return from the IAC to Thermostat like normal. When I contacted Skunk 2 they say just to cap off IAC and it will be fine, I wanted coolant in it since I will be cold starting the car on occasion. What I found was there was a 90deg fitting on top of the upper rad hose where it enters the head, and goes to the Thermostat without going through anything. I took this line and ran it to my IAC, then capped off where it normally went back into the Thermostat, and let it run from the IAC back to thermostat instead.

I know this thread is dead and old, but i want to help anyone looking to solve this issue. I was trolling so hard just to figure this out for myself visually and finally sent skunk 2 an email out of desperation. Low and behold here is the picture they sent me back about how to correctly hook up the IACV to the new ultra manifold.

I honestly thought this was common sense? Seeing how the IACV works and all... all it does is induce a calculated vacuum leak. There is only so many parts in the box and they all have to go somewhere... LOL!

I haven't seen this pic before, but I plan it first time exactly same way . Unfortunately, with original manifoldstay and wireharness there is not enough room for that, so I remote mounted it to the firewall.

Natural Aspirations

DO NOT use the aluminum fittings supplied with the manifold, if you ever attempt to remove them you will be out of luck. Replace with brass fittings.

TracerAcer2.2L

Running coolant through the manifold and TB doesnt cool the intake air, it heats it....

JKaze

What happened with them? I installed couple of those bigger hosebarbs (using also Loctite 542) and later removed one with no problem at all.

Natural Aspirations

Just galled and tore up the threads. I should have known better, always use brass fittings in aluminum.

Just adding the pic to clarify how I mounted IACV with Ultra Street. Bracket is 4mm thick aluminium and straight bolt-on.

edulerp97

So you have no cold start issue.

I used a B16a water neck, they have a fitting for a coolant line, I used a 74mm SK2 tb so it deletes the tb coolant lines so i ran a line from the water neck to the back of the IACV fitting.


Why did you mount it like that was it cause there wasn't much room under?

Also noticed your throttle cable bracket, is it mounted on top of the logo?

I have a spare throtle cable bracket for the skunk2 ultra manifold if any one wants it lmk.

JKaze

Yeah, like I mentioned in post #11.


Yes. When we look how cable meets the throttlebody, I decided to use OE dimensions and angles. There was short period when Skunk2 doesn't supplied anykind bracket with manifold, so I had to made it by myself anyway.

wunfstgsr

Owe it's mounted on a bracket nice!

futrhondaownr

I'm running a pro series 74mm throttle body and it doesn't have the ports coming off of it that go to the iacv. So would it be ok for me to cap them off like this?





Sorry for bumping this old thread.

wunfstgsr

Run i line from the B16 water neck to the IACV and from the IACV to the back of the block i believe it actually goes to the coolant tube thats between the water pump and thermostat housing. You cant leave that open or pluged it will leak heavily.

Natural Aspirations

No need to hook anything to those lines.

wunfstgsr

Make sure the hose is blocked off on the coolant tube on the back of the block figure 8 hose!

I have 2 left over "holes" on the back of my block tiny ones in fact, one was for the pcv I have a catch can so that one is not needed. The other was supposed to go to the IACV but like others with the billet throttle body there's no provisions for a hose.



Top is the pcv i'll just block that, the lower one is to the IACV no? this is a 99 ITR block. ps I know I cant leave them looped it's just to keep out dirt.
