F22A1 to H23 Intake Manifold Swap Questions

[Mishakol129]

Hey guys. I'm thinking of doing this swap because I got to replace the rear mount on my AT and must take the IM off to do so (I figure, hit two birds with one stone, why not). Thing is I have an F22A1 manifold, I heard you have to have a special black box to open the "butterflies". I don't have the black box, so how can I get around this? Another question I have is about the throttle body. The H23 IM I am looking to buy doesn't come with the TB, Its a real bummer.

To summarize:

-Since I have the F22a manifold, will I need the ECU and the "black box" from the a6 or h23 in order for the "butterflies" to open?

-Do I need the H23 throttle body or can I use the F22a1's TB?



Appreciate any and all advice.

the black box is easily found on any 92-93 ex w/ f22a6. you really want to hook up the iab. its worth the trouble. once you get the manifold and box/ wire it up and run a pt6 ecu.

the tb will fit, but its a power loss. try to find an h23 one.

A guy on here says the black box does nothing, its the solenoid valve you want.

In this example, the vacuum reservoir (#25) is just a bottle. The ECU triggers the solenoid valve (#24) and that's what controls when the IAB butterflys open & close. The bottle does'nt CONTROL anything. You could use any kind of airtight bottle as a vacuum reservoir.

Btw what's the name of the black box and the solenoid, I can't find them anywhere on ebay. And how would I "wire it up"?

Go to hondapartsnow.com, enter required info (95 prelude si).

As for wireing, try getting the oem electrical plug from a junkyard lude, cut some wire off with it and wire it to the corresponding plugs in the pt6 ecu (there is a plug diagram on here somewhere for the ecu to tell you what's what, not sure where). also, (cut some ecu plugs/wires aswell to make an oe connection). I know some plugs are interchangeable in our engine bay, not sure if this is.

Thanks but I was reading that the b-flies still come on even without the ECU or the black box. They just come on in the low-end instead. Plus this just seems like too much work and resources to do easily. I know nothing of wiring new connections to ECU's, am a total newb when it comes to that.


So if I'm gonna run it without ecu and the "black box", what are the pros and cons of doing this? Many people online have said to just hook the runners up to vacuum and that will still make the butterflies open.

if you dont hook it up right, you will lose low end power, because once you step on the gas, no more vacuum so they open and it hurts the low end.

There is only one pro and that is the fact that you are still allowed to be a lazy ass. Why do you have such a defeatist mentality with so many of your posts? It's running a couple of wires, that's it. Are you afraid to learn? You're never going to get better at anything if you immediately decide you can't do certain things simply because they're too hard. If you wanted to learn how to solder wire and re-pin an ECU plug it would take a couple minutes of video watching on YouTube and you're done.

You don't want to run them off of vacuum. They open at roughly 1500rpm too early and your engine is not ready for the increased airflow at that point. It all has to do with air velocities. If you open it too early you'll kill the velocity on the low end and have a power drop off.

The F22A throttle body will not work. You'll need one from the H22/H23 or get an aftermarket one.

Okay, you guys are right. Only thing is i'm on a budget and can't really afford another ECU. Besides I already have the P12 which was overpriced. Can't find a throttle body either, they're too expensive or the manifolds don't come with them. I did manage to find one H23 manifold with the TB and the black box, however the guy wanted 225$ for it. I just can't afford that. I sent him a message to lower it to 120$ though.

If I do get the monies however, get the ECU and decide to wire the IAB (what does that even stand for?), is there a guide that can show me how?

Maybe you're misinterpreting what I have been saying. Don't have to be immature and call names.

Don't know if I would buy here, i've heard of people getting ripped off, don't know if I can trust it.

I'm not misinterpreting anything your track record shows, you do this with every thread. If you do not want to hear it you either A go on some rant of he said she said or B it goes in one ear and out the other. I get sick of it when people try and help you and do what you do in the manner you do it in is disrespectful.

IAB= Intake air bypass.
For the IM their are ton's of threads on this topic.
Buying here is safe when using paypal, do not send payment as gift. Buying here is usually cheaper and parts are easily attainable.
Ebay has a few on there at the moment aswell

You can always hit up a junk yard aswell. Yes you can run with no IAB plate, but you sacrifice low end

I like the one without the TB, but that's the problem. Finding a cheap one is not easy. Best I could come up with is this and its for an H22:

However I have an auto TB. Correct me if i'm wrong but I can just switch the parts from my automatic TB to this TB right?
