Individual Throttle Bodies

[Red_Rocket]

Just wondering if anyone has heard of anyone trying to develop this. It would be really awesome if it was.

[airborne200208]

Make your own! Not really all that hard, just alot of research.

[Red_Rocket]

I honestly don't think I could...I would have to find someone who'd be able to do that. Definitely do not have the skills to pull that off lol.

Check March's issue of Import Tuner, I think. There was a Toyota Starlet that had individual throttle bodies. I glanced at it the other day at the store, looked cool.

it's really not that hard to do, i can probably build one, but the hard part is tuning, there is no piggy back out there that can tune for the ITBs that well. tuning itb's is one of the harder things to tune for and not a lot of people have the patience to tune it.

[airborne200208]

tuning is definitely close to rocket science. plus you have to be able to understand pulse theory so you can get the right size trumpets or intake bells. you also need to be able to decide whether to go with a single set or a double set of injectors. lots and lots and lots and lots of time tuning. even with prebuilt sets

yup tons!!!!!!!!!! of tunning on itb's

designing and fabing up an itb setup would not be hard at all. the problem lies with the lack of aftermarket support of camshafts. for an itb setup to function well you need some nasty bump sticks and lots of compression. other wise you could loose power. it is known that high rpm hp typically is lower with itb's due to the lack of helmholtz resonance to help "supercharge" the air fuel mixture. the main gain of itb's is typically nice fat tq and instant throttle response.

you need some headwork to get the full effect

use gsxr 1000 itbs!! they fit damn near anything lol!!. no seriously tho. alot of custom kits consist of the itbs off of a gsxr1000.

yup that's very true.

[F'it_ImFromTx]

That is very true about the gsxr itb's. Allot of motorcycle itb's can fit. I don’t remember the thread specifically but there was a fellow on Honda-tech who made some for his accord out of the itb's from on older model Honda motorcycle. The fabrication should not be a problem if you have access and knowledge of how to use a machine shop. Or if you have bukoo bucks . I agree that the tuning would be the difficult part. Does any one on here have any idea of what some itb's, good head work, and proper tuning would do for our little fitties? Im really curious about what putting that much time and money would result in besides lots of head aches and obscenities.

[GAFIT]

This would require a complete stand alone ecu like a Motec due to our factory DBW and MAF. You're talking big money.

[underdog]

1000rr and 954rr itb's have all the factory sensors. the older one's works too. 929rr?? has smaller plates though. i think the 954rr itbs can support 39hp per cylinder +/-10hp asperated. higher compression with big cam's will allow bigger numbers.

[jx1c3]

since theres a thread about ITB's well im a little new about them. I was thinking bout doing ITB on my K20, but do you guys think it'll make any difference on how the car is driven; ie comfort? because my Fit is a daily driven car.

[HondaFitted2007]

my friend that was looking at my engine said that because how the engine is situated, ITB's would make it hella loud since the intake manifold is closest to the cabin and also, running ITB's could be hazardous in rainy places (like oregon)

[claymore]

Your friend needs to take a closer look. The intake ports on a FIT are on the Front of the engine the farthest away from the cabin part of the engine. The ITBs would be mounted there way in the front of the engine bay. And unless you are in the habit of driving through puddles over your wheels water would not be a major worry.

some peoples kids/\

[wontfit]

i've lived here in portland for awhile now. it doesnt just rain like other places. IT POURS. and it pours forever! never ending rain. ITB's wouldn't be bad here. but the risk is too much. especially on 82nd ave. in se portland . it has the WORST potholes, and they fill with water.
