F22a6 manifold swap FAQ

[accordztech]

What is it?

The f22a6 manifold is from, well duh the f22a6 engine. Only certain models came with this; 91 SE, 92 & 93 ex. Basically the difference is, is that the runners inside the intake plenum,



Like that, see how that thing has 8 holes, well the other engines have only 4 holes.

These extra ports are an extra feature that came in these certain model accords. Basically when the car hit a certain rpm these 4 extra ports open to induce more air flow into the engine, thus creating a bit of power.

Is there a benefit?

Possibly and most likely. The 92 93 ex and 91 se cb7’s were rated a bit higher than the lx, and ex versions of the 91.

When I did the swap I did feel a benefit.

What parts will I need?

You will need gaskets. The intake manifold plenum kit comes with the gasket to the head and the gasket in between the runners, yet you will need to purchase another individual gasket cause there is 2 gaskets needed…also a egr gasket, and possibly some new fuel injector gaskets (#33, #2) since you have to remove those and they are prone to leaking at this age.

Breakdown

Injectors: #33 & #2--> remember you have 4 injectors so you have to get all of them!
Manifold: #15 (2), #20, #12



Of course you can buy these usually in a kit. Honda and aftermarket is basically the same, I got the fuel injector seals at Honda and then the rest is aftermarket.

The IAB control box (black box) is needed if you wish to control it with the ecu. Also a line from the ecu will have to be made on pin a17 to the IAB control box, look at the links and you will see what im talking about.

Additionally you will need the manifold from the f22a6 as well and the ecu for 92 93 ex or 91 se. ECU number is PT6 no matter what ANYONE ELSE TELLS U!

You can run the a6 manifold with the original ecu that you have, but remember the dual runners are controlled by the ECU so you wont have any control over the new setup plus you wont get the full performance of the a6 manifold. I believe there is a different power curve but also a higher redline, I think I go up to 6.1k on my auto now instead of the 5.9 as before.

Is it worth it?

Yes and no. for people like me who is trying to keep a stock complexion and also be smog legal I did it. I wanted a little extra power, plus I found this manifold for very cheap. I mean I gained what, maybe 6 to 10 horses but I really like it, worth the cash in my mind.

Some people though, they probably would be better off by putting their money elsewhere but it’s all up to the tuner =).

How hard is it to install?

Its fairly easy to install, but it just takes time. The hardest part is taking off the old gasket but the rest is quite easy. Just be sure to have some tools, sockets, extensions, and a bit of creativity. I did my swap in about 6 hours with the issue of this one bolt, its just a lot to take off off the top of the car.

Nice threads to look at:

I might of missed some info but that’s why I posted these links…feel free to ask, but please read and take the time to check out the links...happy tunnin.

i did this too, and i also do feel a pretty big difference at higer rpms, the valves open around 4k on my car and from then on it pulls hard all the way through. its a greta mod. i got all my parts including throttle body,intake,iab,gaskets,ecu everything for $50. cant beat that i probably gained around 5-9 hp.

[92accordf20a]

i have the a6 intake but, my black box is broken..

edit: my butterflies stay open all the time, it kinda kills my low end but it starts to pull hard around 3.5k..

[accordztech]

i bypassed the box and just used the module

iono what the box does but it just re routes some air, but i just use that littl emodule heheheh u know it has 2 ports...so i make one in and out and i tested it, works fine

[92accordf20a]

^^^^^could u post a pic???? im not sure where the module is..

haha on the black box right, it has those 2 nipples, then it connects to this little module on the box that is held by the screw, where that grey connector fits onto. i just used that and didnt use the box

[92accordf20a]

so the module is #24 on the picture...

[accordztech]

yes sir

f22a6 engine swap

I just bought a f22a6 engine last weekend and plan on swapping it out this weekend if i get the manifold and ecu do you think i will have any problems get the dual stage to work i was reading some of the material on the post but im still not quite sure

[accordztech]

you shouldnt, i did for some reason but others didnt.

if u get that a6 ecu and hook it up to pin a17 (i think) then run that to the IAB then ur fine.

[MRX]

give me a couple of weeks and i might be able to get the butterfly valves to open at any rpm the user inputs for under $20 without using the a6 ecu.

f22a6 manifold swap FAQ

I didnt think i was going to have to hook up any extra pins on the ecu but i gues i was wrong
What do you mean by IAB I dont know all of the abbrievations yet

[93accord2dr]

the IAB is the black box that controls the butterflies.

Thanks do you know anything about the a17 pin on the ecu im just trying to get all the information i can before my friends and i do the swap this weekend any info will be a help

Have you done this yet?
