F22b1 ITB project.

[AccordSleeperZzZ]

well, i've hit a speedbump. the TPS sensor on the motorcycle throttles is different from that which honda uses. Lookie. ^that piece of metal conntects to the main throttle, then it goex into this... while the honda uses a TPS sensor which looks like this ... sorry, that picture is kinda crappy, but the camera died on me. basically, its a little plastic arm on a spring, and it hits another piece of plastic that's on the throttle body. basically, that means that i have to make an adapter plate so i can get them to mesh. on a more positive note, i finally got my engine dampener to fit on correctly. hah, the car vibrates so pleasantly, and wheel hop is very much eliminated.

could you use the ITB TPS and just rewire it to work with the stock wiring? i know from my research when i had my 240sx that the guys doing ITB setups (not a lot) use hiyabusa ITBs and keep the TPS on there and just rewire it for the stock unit instead of trying to make a square peg fit in a round hole.

[AccordSleeperZzZ]

i thought about it, and if i knew what i was doing, i would give it a wack. but, to be honest, i know next to nothing about wiring / electronics. i can, however, fabricate square peg - round hole conversion kits.

good idea, tho, duder.

hell yeah! glad to see some one doing this. i might attempt this on my f22b1 soon. i remember seeing a thread either here or on HMT(homemadeturbo) where they encountered this very problem. i think they ended up making an adapter plate. the main problem was that the bike unit operated at a different voltage range than the stock one.

im also thinking that his turned the oposite direction from the stock one... but maybe im wrong. anyway, goodluck!

I like seeing people doing this kind of thing to F22 engines and accords....
Does any one remember that guy that supercharged (the real deal... not some fake "electro turbo charged fans"...) a F22A with a bonneville supercharger?!... I thought that was pretty nice!!!
ITB is ballah..... well.... in an accord it is!

[AccordSleeperZzZ]

yea, i think i saw that guy with the bonneville supercharger. it sounded so kick ass.

in regards to the f-series. i'm a big fan. its a nice beefy little motor for what it is. the fact that you can run a good deal of boost on stock internals is always a bonus. i also feel that there is a lack of good quality aftermarket products for our engines. these ITB's are really just a prototype, if they work, i wanna try repositioning them (with the stacks angled up towards the hood). that supposedly gets much better airflow. i found this out after i wrestled them into position.

anyhoo. as soon as i can scrape together some aluminum stock and some machineshop time, i'll have that adapter plate fabbed up

thanks for the interest.

[gianinline]

Good work man!
Nice to know you are doing that!
F22 rocks!

[AccordSleeperZzZ]

spent about an hour and a half getting all the dimensions of the TPS sensors with my trusty dial calipers.

soooo... i drew it up in autocad and plotted out what the adapter plate is gonna look like.

see what you think:


the work area.




a teaser pic.



while i'm in the machine shop tomorrow, i'll try and scrounge up some plate aluminum for the plate and get this project finished.

Much respect and props man....dood i hate decimal coversions....but i love ITBs....cannot wait for that adapter to be done....

[AccordSleeperZzZ]

well. slight progress.

i found a piece of aluminum to use for my adapter plate. someone's project, and they broke a tap off in it. sucks to be them.



i then milled it down to a useable size. [approx. 1-3/4" X 3"] i even "jeweled" the top of the plate and it turned out with a really cool surface finish, but the camera couldn't really pick it up very well.





unfortunately, where this individual broke the tap, restricted how wide i could make the plate. but, it was shiny and the nicest piece of scrap, and too good to pass up.

here's how the TPS will sit on the ITB's



and here's an autocad drawing of the "reorganized" adapter plate design. (don't know how well this one turned out.)



also, i figured since the ITBs are gonna make the enginebay look sp kickass, i figured the whole bay oughta look good... so, i'm repainting the valve cover. i originally repainted it a metallic blue, which looked real good but it started to come off because i forgot to 'pit' the aluminum before i painted. alas, the new paint job should look awesome and a half. new color, more detail, yadda yadda yadda. anyhoo. everyone like pictures. so here's a few more of the project vehicle.

down to aluminum




hopefully, i can finish milling the plate before the weekend.

and this concludes my infinately small progress that i post to keep interest and to keep my thread from going "Archived" .

[GhostAccord]

Sweet looking setup, we'll have to compare notes when it comes to tuning. Probably not too many differences between the F22B2 & B1 when it comes to getting these things to idle. Are you changing any internals or keeping the stock valve train?

[AccordSleeperZzZ]

stock internals, i think. i would love to get some real performance internals done to the engine(can you say high compression pistons) but as of right now, i am strapped for cash. hence my budget-build ITB setup. haha

i'd like to pick up a spare head for cheap and gradually build it up, while i cruise around on this one, then swap them. but, in short - stock internals for now.

yea, getting the idle right is definately gonna be the thing. i havn't checked out your build yet, but i'll give it a look. nice to see i'm not the only one doing it

[racerpat94]

i have 12:1 pistons in my F22b1. i just picked up a clean head for it for $50 to get my car running. i will eventually get a built H22 head. when i do, i wont be needing this one....

wow.....another F22 ITB build up! what a day! ITB fever sweeping the accord community?

Well your one up on me with the help of the VTEC to begin with. I'm sure that will help you out quite a bit. You'll get a nice idle and the gains of the higher RPM's sweet deal.

Cheers and good luck with the build

[hurleyint]

very nice project so far. i love to see dyno charts at some point.

[mark_is_gay]

thats pretty sweet, good luck with ur project. Lets see some numbers, or a vid when u get it done...

[AccordSleeperZzZ]

1st. - thanks for all the positive feedback, everyone!

also, i'll be sure to get a video up once they're all hooked up. hecks, maybe i'll shoot a video soon with the current setup so we can compare before / after. if anyone's interested in video, that is.

as for hp gains - i'm definately gfonna put the ole accord on the dyno when it's done just to see what i'm making. but, like i've said before i'm not looking for any kind of massive power gains. i'm more looking for some more mid-range torque / better throttle response.

And GhostAccord - i wouldn't say i have much up on you since you're actually having some fun with your internals.

cheers.

[racerpat94]

i figure with the ITBs you will at least be able to carry power further up in the rpm range before it starts to fall off. throttle response should be greatly improved too. if you are looking for a relatively cheap comp boost, try a set of rsx type S pistons. youll have to bore your block out, but in the end you'll have between 11-12:1 static CR which would compliment those itbs and a cam VERY nicely.

looking forward t osome updates!

[AccordSleeperZzZ]

well, not too much in the way of updates for this project, but a f22 non-vtec just fell into my lap(dad has a wrecked accord) that i can toy with. i hope to do some work to it this summer. maybe a vtec head swap and those hi comp. pistons i've been drooling over. and perhaps bolt these throttles onto that setup. who knows.

i'm not sure if this qualifies as progress to my project, but i have another engine to play with and i don't have to worry about downtime, so... i felt i should tell someone. hah.
