Ok I've done a search on this one but am not certain about this one because I have only seen speculation but no definite answers. I am using a B16 manifold, and by using the search, have learned that d, b, f, and h series TBs and TPS sensors are interchangeable. That being said, if I used an H22A TB with the manifold, would I have to match the IACV with the TB on the H22? Or are they also all interchangeable? If it helps I'm running a OBD0 PR3 ECU. Should I stick with a certain IAC valve or does it not matter? Basically I want to know if I can mix and match...

 

Not enough information. Not only engine type, but also year. There's probably less than 6 different IAC valves across the years, so get on some honda parts websites & check part numbers.

Ok, here's what I got... a '95 H22A throttle body (w/ FITV) and a B16 manifold. I'm wondering if the IACV mounted on the manifold will work with the one on the 'lude's TB

 

what i do know is that f22=h23=h22 OBD1 IACVs, while not identical, have the same bolt/port/connector styles and work interchangeably. coolant nipples point different directions which is no big deal.

id just go with the iacv that bolts onto your manifold and matches your wiring, why do you need to match it to the TB? they are unrelated...

 

They do hook up to each other, right? I don't have a diagram for it yet...

Here's where it gets complicated... they are both obd1, including the manifold, but the car is obd0. i'm wondering if i'm going to run into complications with this setup...

 

so what hook up to each other? the TB and IACV? if youre talking about coolant lines, of course they do, as long as you run coolant lines between them... lol

if youre going to be running the car & motor as OBD0, you dont need most of the OBD1 sensors and whatnot... if you can run the proper fuel/ign maps, doesnt really matter what level of obd management, as long as everything the ECU looks for is there. and obd0 ecu wont be looking for an obd1 iacv... dont know much about obd0, did it even use an iacv at all?

yep pretty much, even B series work on H series and visa versa......just the nipples are pointed different directions.

$hit. this is what happens when you try to combine different hondas into one setup. i wish i knew to be honest with you whether it uses it or not. from what it looks like, the accord tb's don't have that iacv/fitv mounted below, but the 'ludes do. i know that in my h22 there are 2 of these stupid things, the one on the tb and the one on the manifold that has the same bolt pattern as the d-series iacv. what i need to find out is whether or not the b16a crx sir's were using these. i'm working with a del sol vtec manifold so i'm sure it's totally different

 

Here's some more info...

I'm installing:
1) A JDM '89 B16A head
2) A JDM engine harness of the same generation
3) A USDM '95 H22A TB (with the FITV or IACV or whatever the ***** it is)
4) A '94 del Sol VTEC OBD1 manifold
5) A JDM PR3 ECU (which will be socketed and running BRE)
6) Going into an EF hatch

Now, from what I've researched, the OBD0 manifold doesn't even have the holes for the IACV. Now, I could be wrong, but don't the two control valves work together? Do I need these parts to ensure proper workmanship? This is where I am stuck

 

fiv = fast idle valve, raises idle when cold. based only on coolant temp
iacv = idle air control valve. adjusts idle based on load and other conditions (ever wonder what brought the idle back up a bit after you turn the a/c on?). its the one with the electrical connector on it.

both work independently, but serve similar functions.

youre using obd0 wiring and ecu. so you need obd0 sensors and electrical components... you can use any intake manifold you could want, obd1, obd2, whatever... anything extra find a way to either cap off, plug up, or remove, youre only going to be using what the ECU looks for. so as long as you have everything that normally would be on an OBD-0 engine/car, youre good. anything extra is just leftovers, being that that part came from an obd1+ car.

 

thanks you guys answered my question about if a f22 iacv would work with my h22 manifold? lol so thanks guys
