I was searching the web and came across this site talking about individual throttle bodies i have seen this on other cars but what does it really do for the car does it give it more horse power? or what and is it worth doing it to your car? and if anyone has more info could you pass it along thanks

oh by the way here is the site

thanks Robbie

yeah it does give you more power.

To determine if you should do it.. you should give us some more info..

your engine, power goals, budget, etc.

i have a DOHC ZC money is not really a problem (and ya i no its a ZC but this is what i want to do right now iam goingto be looking at getting a S2000 next year) neways i want to push like 250hp in my crx

chris_si98

if you want 250hp.. itb's won't do it.

Looks like your only option is f/i

imported_crx__4u2nv

what do you mean f/i?

chris_si98

force induction.

turbo kit/supercharger or you can use nitrous if you really want..

do some more research.

www.d-series.org is a good place if you want 250hp out of your zc

yeah i have a 14b turbo from a talon was thinking on doing that to the ZC with cams and domed pistons along with a nice port and polish and a valve job that should get me close to 250 eh

chris_si98

a lot of variables come into play on a turbo setup. 14b isn't the largest turbo..but with an aggressive tune and the boost high enough I don't see why it won't make 250hp.

Do you want 250whp? or 250 to the fly? 250whp might be a little difficult and you will definately need to atleast get low compression pistons

ITB would be one of the final stages of NA tuning. Though, many guys run it with stock Type R engines. You need a full programable ECU to tune the engine.

imported_crx__4u2nv

I thought domed pistons increase compresion. please correct me if this is not true

LEITNER

dont do itb's not worth the aggrivation. a tuning head ache and in your case wont help much. full built high compression engines will benefit from itbs but i still woudnt do it. you can get just as much power from a throttle body set up. look at most of the fastest na drag cars, they run a tb not itb's.

yes domes increase compression.

I remeber mr leitners headaches with this set up ..not a great option for a daily driver ......tracking might be fun if you have the time.......

imported_Team Rukus

sry for posting a stupid question but how much hp would someone expect off an itb setup on a stock ctr motor after tuning.
also how much do itb's go for? reliable one ofcourse.

imported_crx__4u2nv

thanks for the info guys very helpful

ITB's are way too expensive!!!
Like steve said they're a tuning nightmare. Not very good for a daily driver if you ask me....especially with our changes in climate up here.
There are plenty of good intake manifolds out there to choose from, even some that cost as much as ITB's.

LEITNER

questions answered.

I always wondered about ITB'S, where's the air filter?

zeeman

iTrader: (1)

well if you were to use some sort of air filtration system it would have to be 4 smaller filters or 4 little screens. I've seen people use the filters from carbs, or something like this:

But personally i think something like this would be better, not to mention how sweet it looks:

I know someone with twin carbs on his civic. Isnt that like I/T also?

LEITNER

no thats carbs webers/mikuni the a/f ratio is controlled by jets that you have to change as the weather changes, fuel injection is eliminated. itb's are fuel injection.
