F22a6 Manifold

[Shadow1]

how do you tell if you have an h23 mani or f22a6?
is it really better for turbo to take out the runners?
In that case if turbo would there be a difference still if you were to use to f22a4,1 mani?
I mean why buy the f22a6 or h23 mani if it's the same as f22a4,1 when taking out the runners
however the mani I have does seem to have alot larger head before the runners that lead up to the head

if you had a turbo then deleting the butterfly valves would be a good idea. but if you dont have alot done to your motor or at LEAST nitrous then doing that would be kind of pointless IMO.

the h23 and f22a6 IM are NOT the same as the a1 and a4 IM. having the extra 4 runners increases airflow so you can get more HP. the a1 and a4 IM only have 4 runners. the h23 and a6 IM have 8.

Absolutely correct and the h23 manifold is bigger than the A6

Don’t be an idiot just read it not that hard
I imagine you don’t use aim or anything cuz im not sure you would understand people's online jargon being how you can’t even separate a few fragmented sentences

Before you tell somebody an idiot, make sure you're not an idiot yourself. People here use proper grammar. So make use of it like everybody does!

wel not eveyone. i know i dont sometimes....i think.....

oh well.


anyways. yeah. what we both said about the IM is true.

yes I know , and I do as well lol.. But the insult should never said , that's what I meant. Ehh , sometimes it leads to flame wars. LOL!

true. but its over now. anyways. lol


if you need more help man, dont hesitate to ask.

hahaha ...im just laughing while reading these posts...but thx guys for the knowledge...by wire tying the IAB open the car is crazy fast... ...well...just faster than wat is was...but im definitely gonna fix that problem...its amazing how when u dont think theres something wrong with ur car and u turn around and find that there is something wrong with ur car ...it goes to show that the CEL doesnt come on for everything...

How can you tell if the IAB is opening or not?

How can you tell if the IAB is opening or not?

you can here the iab open because the car gets deepper in sound and it pulls a little bit harder

[ilovemycb7]

Hmm, I don't know if I want to mess around at 5k in such an old car though... I guess I will sometime and see if I can feel any change. Or hear anything...

[NAiL05]

Unplug it it will stay open. They usually open around 4000 rpm.

when rev up the car...but not with the peddle, but with throttlebody(i cant think of the name of that lil lever), as soon as u rev past 5k rpm...u should see the lever that is connected to the diaphram(on other side of manifold) being pulled to open the internal butterflies in the manifold...but the diaphram on my car is not pulling the lever at high RPMs...therefore, theres a problem...

what vacumm sorce can you hook it up to? other than the IAB box i mean.


i have a nipple on the short ram intake i have on that isnt being used(when i ordered it from ebay they didnt send me that tube that runs from the intake to the valve cover. i just put a mini filter on the valve cover.) can i hook it up to that? or is there something else?

[ilovemycb7]

Yeah, so I've taken mine up a few times and I don't feel any difference over 5k. Maybe it's me expecting more, but I need to look into this.

I read in one of the referenced posts that someone made the iab's stay closed by hooking them to a vacuum source (presumably the intake manifold). Does this mean that if the vehicle was turbo'd and the iab's were still vacuum referenced that the iab's would open under boost? Anyone know? Because that would be an easy way to have the iab's open at a certain rpm when using a different than stock ecu (like a p06 for a swap into a civic ) If that worked then it would still allow the secondary runners to be closed under part throttle and keep some of that low end torque

i would think so because all that boost pressure would cause the butterflies to open up when present...but idunno...but it sounds good...
