F22b1 ITB project.

[AccordSleeperZzZ]

the 95 accord is getting a little work done. *what's the deal* alrighty then. so, i have some spare time on my hands. this is a result of attending college in a small town and having to wait for my job history to come back from home. so, i acquired a set of used individual throttle bodies from ebay for about $45 shipped. they're 38mm off of a honda 600. i also have a spare f22b1 intake manifold that i picked up for real cheap a while ago. add to that free access to a machine shop(the college's) and a moderately skilled machinist who works for free (yours truly) plus about $70 of spare parts so far, and you have a set of ITB's coming along nicely. *pictures and procedures so far* the original intake manifold. throttles. it came with all the vacuum lines and stuff, i just bought a set of vacuum line plugs and plugged them all up nice and tight. ban-sawed. after i ban-sawed the manifold, i milled it down flat, then i cut in-betwen each 'tube' of the casting so i had enough room to clamp down the radiator tube(the biggest the guy at the parts store could find) that i used to couple the throttles to the intake manifold. which was a major bitch to say the least. here's what it looks like fabbed up. (throttles and intake manifold coupled together). . the seal on the radiator hose is pretty tight. tight enough for them to stay together nicely, but of course i'm still gonna clamp them down with various sized hose clamps that i bought, as well as some 'high tack gasket sealant'to ensure that i'm not leaking any air. next, i had to address the vacuum collector(vacuum box, whatever). i rooted through the scrap bin looking for something suitable until i stumbled upon gold! and by gold i mean a hunk of steel 1-3/16" square stock that someone had tacked a bit of steel rod to for some reason. i sawed off the rod, then my buddy Kevin milled down the square stock down past the welds(ended up as rectangular stock because of this). then, i bore a 3/4 hole through it on the lathe. afterwards, i cut off about 3/8" from the bottom(that didn't have the hole cut through it) to use as a 'cap' for the vacuum box. i faced both pieces off on the lathed, and its an alright finish on them, but to ensure a good seal i bought a roll of black rubber gasket paper. pictured above. 'cap'. that's where i am so far. i have to tap 2 holes through the top of the vacuum box 'cap' and box itself so i can screw down the cap and get a good seal. afterwards i have to tap all the holes for the various vacuum lines that currently attach themselves to my intake manifold. i'll keep ya'll updated as i make progress. -Chris

looks awesome dood. Dyno your car to see the results. Can't wait to see the end product.

[AccordSleeperZzZ]

thanks. yea, i'm not hoping for any crazy power gains. i really just wanted a fun winter project, and have something reliable, if possible. that, and ITB's look kickass IMO.

[BlkChryKord]

Props for ingenuity although not the best way to go about it using that radiator hose but good job so far. Makes me think about cutting up my spare F23 intake manifold.

[AccordSleeperZzZ]

yea, i know that the radiator hose isn't the best potion,but, all the throttles are joined togetherand they wouldn't line up dead-nuts with the manifold where i cut it. and i didn't want to cut it down any further because i wanted to keep the EGR there so i didn't throw up any engine codes. well, as few as possible, at least.

[AccordSleeperZzZ]

machine shop closed.clamped and sealed everthing then i got bored. so i mocked up the throttles w/ EGR and fuel rail.

[street_accord94]

how do you plan on tuning that you would need to worry about EGR?

[AccordSleeperZzZ]

i just left it on there for now, i figured i could always take it off. when it comes time for tuning i'll worry. now i'm just trying to get all my fab work done. i t looked more complete so i threw it on there. ha.

[CD8coupeSiR]

thats sick dude, nice job, i was thinking of doing that too, but never had the time. if you ever think of selling them hit me up!!!

[The-Kid]

man. some ppl here know how to fab stuff. You guys could really make money with this. Not everyone makes anything for a F22B1

[AccordSleeperZzZ]

thanks guys. yea if i had the time i'd make parts for people, no doubt. hell, i could now, i just couldn't promise it within any given time period, hah.

[WhiteOnRice]

Heh, you did a lot of work in 2 days!

[AccordSleeperZzZ]

actually, i got the throttles back around Jan. 12. cleaned them to the point where one could eat off of them and plugged up all the vacuum lines. and i just re-started working on this stuff last week when i ban-sawed the manifold. the rest has been spread out over about 10 days, whenever i could get in the machine-shop.

[Slomies]

nice work! somewhere down the line I'd like to do this on my h23 since I've got an extra manifold lying around ...

[AccordSleeperZzZ]

yea, i've been thinking with this setup, i'll be sucking in oodles more air, well a bit more anyway. so i believe stepping up the injectors would be a justified move. anyone know what other(bigger) honda injectors would fit in the f22b1 fuel rail / manifold? or even dsm injectors or something that i could fit without toooo much modification. any help?

[yellowbus]

sweet project. i would like to see how it turns out and what kind of power the f series will put down with ITB's.

[TouringAccord]

yep, H22A1 injectors. You'll find them in the 92-96 Preludes. They are 345cc injectors. They use the resistor box just like the stock injectors. I may have a set for sale if your interested, PM me if so.

[AccordSleeperZzZ]

woot. i was afraid i was gonna have to "afro-engineer" something.

[Andryzzle]

im running precision 440s in my stock stuff so you should be alright to find whatever. awesome idea though.

[AccordSleeperZzZ]

sweet. tomorrow i should be able to go to the parts store and get some material for my re-routed vacuum lines, which is gonna be a big ole heap of progress once its done.
what kinda tuning / fuel management you running, btw?

[Andryzzle]

crome on a chipped p28

[street_accord94]

if you choose to run that you wont need to worry about the egr (what i was getting at in my earlier post)

[kurvy]

yo son taht shit is crazy maybe i should try that

[AccordSleeperZzZ]

how about i finished machining my vacuum box completely, and i have no digital camera to show off.

oh well, hopefully by the time i get a camera, the map sensor's housing(the only thing left) will be done, and i can put up pics of everything on the car.

[AccordSleeperZzZ]

pictures of progress. . . . everyone likes pictures!

vacuum collector box







IACV plug.







everything should be going on this week, if i can get the syncronizing tool. if all goes well - i'll try and put some video up.
