F22a6 intake swap

[urbanrunner]

I have a f22a1, and i have read on other forums that the f22a6 intake manifold has dual runners, which is like 8 inlet hole for air opposed to the 4 on the f22a1 intake manifold. I also heard that you can swap these out prety easily. My question is can i swap these without an ecu swap, or will i have to get an ecu as well. And i fi do need an ecu will it have to be from a automatic tranny car since my car is an automatic???
I want to do this next monday but i wanna make sure its worth and and i can do it easily without pobelms

[urbanrunner]

anybody? JUst need somehelp with this...?

It will work without the ecu, but I think the butterfly valves won't open up for the dual runners. You want to get the same ecu transmission wise. I'm not too knowledgable on this, but that is just what I remember from reading stuff on the forum. I plan on doing this mod soon as well.

son...control yourself, your all over the internet with this lol You'll get the same answers here as u would on AT. Try to stick to ecu's compadible to ur tranny but it doesn't matter any ecu from 90-93 accords WILL work. You don't need an a6 ecu...you only need it if u want to have the butterflies closed before 4700 rpm. If u don't have it then they will just stay open all the time like mine.

do u notice a loss of power at all? ANd someone on HS told me that if i hook up an extra vacumm line the the butter flies will open at full throttle....

Oh yes and i am calm just don't want to make any mistakes!

i did not notice a loss in power but rather a gain around 3800-4100 rpm then a surge of power at 4900 rpm till where ever you shift
The only way you'd be able to have the butterflies open at only full throttle is if you had the a6 ecu to close them in the first place.
I haven't heard of this being done but i'm pretty sure it can happen. You'd have to ask the HS ppl how to do it cause i haven't heard of it.
It'd be a nice feature tho and nice to learn

The butterfly solenoid only needs a 12v positive signal to open up, so you can rig up your own switch to open them whenever you want... that way you don't even need to bother with getting another ECU.

[urbanrunner]

do u know where the solienoid terminal is...iwill try a 12 v switch then

I'm just curious....why would you only want the IMTV to open at full throttle?

BTW, I just remembered, fuel pressure on A6 cars is 40psi, vs 36 psi on A1 and A4 cars. So it might not be a bad idea to trow in an EX fuel pump so it doesn't lean out at higher RPM when the butterflies open.

humm, really..ill look into that.

okay ive found a f22a6 intake manifold im juss wondering u were talkin about gettin a better fuel pump but i have a 90 ex so will i have to get a new pump and how much gain will this give? (man i love our junkyard) and also how will i go about cleanin it and is there ne way to determine if its worthit to take?

[accordztech]

i dont even know if there is a differnt in fuel pumps....

but i did pull another manifold today, now i have 2 f22a6 =).

im cleaning out the egr ports, and just cleaning out the interior and making it nice and shinny...


the only way to know if the fuel pump is differnt is looking at the part numbers which sometimes are differnt due to wiring.

im not going to worry about no fuel pump...=)...but i will look into it in the future.

[wunda who]

now that u answered that how long u think it'll take to throw in about an hour and a half or less..........(im thinkin less) well neway tell me how the gain is with it

[accordztech]

it took me about 40 minutes taking it off...the engine i had was really jammed and been in a accident.

but not long, i say a 2 hour job.
