I've been collecting some ideas for my senior project that I have to do... and one thing that I'm not too familiar with are Individual Throttle Body setups. From what I have seen, they have some really decent gains, but generally require some dyno time to make any power. From the options I was looking at, I was looking at purchasing some CBR 954 ITB's, as these seem to be the easiest to work with as the injectors are identical to Civic ones, and the TPS requires a slight modification to work properly. I wanted to gather some of your thoughts for this. From what I have added up, the total cost for parts seem to be about $400-$500... which means in reality, I'll prolly expect it to be a couple hundred more for miscelanious stuff. So I was thinking stopping there and have a pretty unique setup.

But... now I was thinking about taking this setup a step further, and introducing nitrous to it. I have only found 3 threads on H-T that contained the word itb and nitrous... one had a picture of a setup, but it wasn't a very good shot. So I assume it is at least doable. On a stock b16a, found that ZEX offers a direct port setup that can essentially offer a 50 shot which would be perfect. The price kinda sucks at $650... but it could be worse. From what I've been thinking, just tapping into the velocity stack would most likely work. Also heard of a suggestion to tap into the bikes stock injector location. Now, is there any importance as to where the location of the nitrous nozzle will be as far as atomization and the fuel injector itself?

Am I completely dreaming here of doing a nitrous setup with ITB's...?

Thanks. That was the picture I was referring too... unfortunetly, I have found no other shots and no other details on the setup.

 

Yes, I would also like to atempt this as well, not only is there a lack of information on this but a lack of nitrous info in general as it pertains to anything beyond a standard kit. I would really like to see a nitrous forum.

I ran a dry setup with a standard intake manifold on my Prelude. It's not complicated at all.

I just want to make sure that with the direct port setup, that it won't be too close to the injectors, or won't have time to atomize properly and can cause engine damage.

 

OT: haha, you can always tell if it's a japanese car by all the firesleeve and clear light blue tubing. That car looks badass though, any other pics of it?

.....not by the brake MC on the right-hand side of the car?

Dan that's a nice setup

Yea, I saw that too and that's how I confirmed it was a japanese car. Little obvious to point out though

 

that things got neons on it

 

So... anyone have some actual tech info they'd like to share. Afterall, I always hear people bitching about how this site is full of bullshit... and then when tech questions are asked... well, you can figure out the rest.

 

.....if it's any consolation, I intend to run a similar setup.

I have to finish getting the stuff together, but hopefully I'll have it all done this year.

I'm just going to run an off the shelf itb kit and some of those noszles that combine injector and jets together... I'm just going to start off with a small 50 shot and work my way up to 100 or 150 shot or so.....

The Noszle idea looks really interesting. Too bad it's really expensive.

Anyways, it's good to know someone with a similar idea -- however I think I really wanna try the traditional idea and tap into the velocity stack and spray right there. I just need some hardcore technical information if there will be any limits or obstacles to doing this method.

 

Any more feedback?

fwiw, I've heard of at least one usdm car running a setup like we're talking about.

This person mounted the individual jets on the firewall and aimed them - one jet per itb...

I've heard that this was one of the people on mtv's "i'm a streetracer" episode.

I cannot confirm, however.

My thoughts are that this will be less accurate at speed due to wind blowing in/ through the engine bay. That's why I want to use the nos-zles.....

I figure it's pricey, but maybe I can find a used system and considering the cost of itb's, the nos-zles would be a drop in the bucket.

considering the closeness of the noszle to the injector i dont think you would have a problem with a fogger in the volocity stack. infact it might even pull in more air. just get it to aim straight in and not to the wall of the volocity stack due to the curve of the stack.

 

Did anyone else notice the suspension

Unibody drag car.

 

Thanks for clearing that up! Not a drag fan so what I saw seemed a little strange!

 

looks like he mounted the nozzles in fromt on the throttle plate right behing the velocity stack. normally a DP system mounts on the other side but i guess room in limited with ITBs. I'm research this as well fo rmy GSR project. with the way the butterflys open you can mount them right behind the throttle if you have room. may have to mount on the underside though.


I agree we need a nitrous forum. A place for the bastard children of autocraft to hang out.

 

i was going to do this set up about a year ago it was gonna be a 50 shot with NOS direct port kit on a b16 and slowly changed over to an lsvtec with nitrous.

i abandoned the ITB idea and sold them due to the fact that i was told i cant use hondata with ITBs and that i would have to do a 75 shot minimal. in the end it just ended up like a tuners nightmare and very sloppy. i think one day i would like to actually attempt it with a sleeved block and maybe a 100 shot

 

looks like a 2 stage setup. He speaks my language.

 

i noticed hondata s200 says it comes with a nitrous controller. is this simply a window switch or can it be used like the nitrous mastermind to vary shot size by pulsing the soleniod.
