H23 Intake Manifold

[1991_HondaAcc]

Im looking at buying just an intake manifold with no sensors's or anything else. Would i be able to switch the throttle body and everything else over from the f22 IM?

Thanks for any help.

Yea but whats the point of using an f22a throttle body with a bigger plenum.

No it come's with the H23 Throttle body. just none of the sensor's

You can't use an F22 TB on a H23 Intake manifold/plenum. It won't fit.
As far as sensors go,
TPS - interchangeable, just makee sure to calibrate it.

IACV-also bolts up.

the air boost valve- fits.

intake air tempature- yes

FIV-The fast idle thermo valve is on the underide of the H23 T.B. so...make sure you get that, if it didnt come with it already

[f20bracer]

fiv?? if that doesnt come with it then wat should i do would that be interchangable?

[Cb7GHOST]

If the h23 throttle body you have doesn't have the FIValve attached to the bottom of it, get one off ebay or someone here who's selling it (at your own risk lol). The F22 one won't work.

just find a complete h23 IM, its way easier than trying to peice one together.

i did buy the whole intake mani buit they told me some stuff ewas missing by anychance does anyone have a pic of this valve?? so i know wat im lookin for or at least describe wat it looks like?

[Cb7GHOST]

ok you see that thing circled RED? thats the Fast idle thermo valve do you have that?

[f20bracer]

nope i got to et that then from the junk yard.. or does anyone from here have one? lol

[f20bracer]

one more question cb7ghost does it matter if the throttle body came from an auto or 5spd car?? if so how can i use a auto throttle body with my 5spd accord?

i got a FIV for an h23 i'll PM you


p.s. yes you can use an auto TB on a 5speed

i just looked on ebay and i read that the f22a and the h23a one are the same well thats the ones they sell for the prelude si h23a it says it fits the f22a so i dont get why it wouldnt fit??

[93twodoorLX]

you can trust me and cb7ghost on this. i have a f22a1 with an H23 manifold, i looked, and no they are NOT i repeat NOT the same. they will in no way work on the h23 TB i promise you, ebay only says they are all the same because

1. they are dumb as f***
and 2. they just wanna make a quick buck so they say "oh yeah it fits f22 h22 TYPE R TYPE S VTAK" they tell you whatever. but in fact it is not all the same. just looking out dont want you dropping loot on something that wont fit and you cant return when you can just but one that i promise you WILL fit and WILL work. let me know i can get pics if you need em. but not til tomorrow afternoon
