Throttle body spacer that fits both 1zz and 1nz TB's and can be made to order with a tap for a nitrous nozzle.

I need to guage interest on the first order so i can create accurate pricing.

I need to know who would be interested, and an approximate amount that people would be willing to pay.

Can we specify who's fogger we want to use as there are critical design differences between brands?

Can you design one that smoothly transitions the 1zz throttle body to the 1nz intake manifold. It seems like there's an abrupt transition for those who are putting the 1zz throttle bodies on their Yaris.

I suppose you could, as long as it was provided to us when you ordered it, because we need to make sure the threads match perfectly so when you screw in the fogger, its facing the right way. We were planning on using a right-angle fogger.

I dont think I know quite what you mean.
do you mean a middle ground? a slight restriction on the 1zz tb while still more flow than the 1nz TB?

or like a port match?

If I'm not mistaken, the 1zz TB is a larger opening size. It is being bolted to the 1nz intake manifold which has a smaller opening. I figured that an abrupt interface from larger diameter to smaller diameter would cause unwanted turbulence at the transition.

My question was... can your adapter plate taper from the larger diameter opening to the smaller diameter opening to lessen the turbulence?

yarstar
04-07-2009, 03:31 PM
Noogie may be on to something with that low turbulence idea.

What do you think Alex?

What do you think Alex?

He is on to something, otherwise all the spacer will do to the guys with the 1zz tb is allow the air to come at the intake manifold at a higher velocity and when it enters, it would be more turbulent than it is without a spacer. the spacer could/would actually cause a larger disturbance to the entering air.

taper would pretty much be required for those of us with the 1zz tb.

AlexNet0
04-07-2009, 06:53 PM
I could alter it or make a different one that did that, but I think that the opening on the Intake mani actually matches that of the 1zz TB, I actually didnt look at the size differences of the TB and intake mani, so if someone else who has recently done the mod who actually looked could tell us, that would be awesome.

Lt. Noogie was right, the intake manifold opening is ever so slightly smaller in diameter than the inner diameter of the 1zz tb. some of the flow is getting restricted, how much exactly, i am not sure.

04-07-2009, 08:09 PM
I'm on my phone seeing fast and furious so bear with me lol

I'm going to be purchasing the machine if the test product goes well so it will be possible to machine a seperate one for the 1nz as well if there is turbulent air flow

It was that we did this on the basis that the 1zz tb mated to the 1nz manifold and thought the size would have mated, thus allowing an easier and broader range of produvtion

But thanks for bringing up that there is an actual size difference it means a lot to get it correct for the 1nz which is the more important engine of the bunch

Buy a filing bit for a dremel and port the manifold? :iono:
lol jk

I will do this then - make a model for mating the 1zz and 1nz mani
- make a model for the 1nz straight through
and - keep this current one so people that want to port the intake manifold can do so and still enjoy this part.

lol i'm not going to lie and say this thing picks up 10hp all by itself, thats just not going to gain good interest in what it is

Well, here's the thing, you increase the length of the intake which increases air velocity only slightly, so if any other gains came from other spacers it would net the same as it is just as thick if not thicker. I have heard as much of a 2-3hp gain with increased throttle sensitivity from scionlife users.

I can make these to your preference without a doubt, but the sole reason they were created were to give the community another option as far as FI goes with added a nitrous fogger, which can lead to any gains you want as long as it is in reason of safety.

@Nexus1155: Is it a good idea to have a fogger for the TB as well as the mani (supposing of course that RH finally starts selling it)? Are there any benefits to using the TB fogger instead of the mani fogger(s)?

YarisSedan
04-08-2009, 02:24 PM
I think a throttle fogger just makes things simpler. Throttle body gives it a more direct port to each cylinder so a more precise measurement. So depending on your budget and ease of installation throttle body injection is the way to go.

Nexus1155
04-08-2009, 02:29 PM
This was specifically made for stock manifolds, something like holdeners manifold injects directly into each intake tract and adding more on top of it, i honestly would not recommend it IMHO(I mean what we are making adds the nitrous directly to the air charge, in a sense you can do it on holdeners but i dont think you will need more jetting than what you can do with holdeners). But that is when he does sell it.

The thing is that with the stock manifold tapping plastic and having something stable in there is a little more unstable than metal. And also that alot of plastic manifolds have a hard time with dealing with nitrous directly installed on it. I know the manifolds are made from a different composite of plastic.

The thing is that if you have a hot engine, spray something cold and heat it up and then cold again and repeat, that plastic manifold can and will crack after useage like that. Its pretty basic principles on expand and contract with different materials. While using the throttle body unit, you inject straight on the metal and it distributes it without issue, and the tb spacer takes all of the cold.

***and exactly what YarisSedan said as well it is simpler and cheaper in the long run

Have you thought of putting any type of helix design on the inside of the spacer to hep with air flow velocity. Like a lot of the performance throttle body spacers have.

Not a bad idea, although it would probably take a lot more R&D to get it right, and could also affect the final price.

04-08-2009, 11:50 PM
there would need to be alot more code to be written for it, but ultimately i don't think they do much anyways, if the stock intake is straight, it wouldnt make much different if one was just in the middle IMO.

So it looks like the fogger option will be standard

just remember that if you want the fogger option, and you dont want the one that will be provided, then you must pick one out before you order it from us, when that time comes.

I don't really mind either way, but if you do choose to anodize, I'd really prefer a graphite gray color to match the pulleys (I don't have any other colors under there, and I'd rather keep it that way). If gray isn't an option, then I'd go for black.

if you want optimum performance, make it from phenolic

Phenolic resin can include any of various synthetic thermosetting resins such as Bakelite, obtained by the reaction of phenols with simple aldehydes such as formaldehyde. Phenolics can be used to make molded products including pool balls, laboratory countertops,[1] and as coatings and adhesives.

Phenolic material properties are useful in myriad industrial applications. Phenolic laminates are made by impregnating one or more layers of a base material such as paper, fiberglass or cotton with phenolic resin and laminating the resin-saturated base material under heat and pressure. The resin fully polymerizes (cures) during this process. The base material choice depends on the intended application of the finished product. Paper phenolics are used in manufacturing electrical components such as punch-through boards and household laminates. Glass phenolics are particularly well suited for use in the high speed bearing market. Phenolic micro-balloons are used for density control.

so, garm, you can cut and paste!

but why would i suggest using a phenolic plastic over aluminum? anyone?

phenolic spacer to keep IAT down because it doesn't conduct heat. It might be a more suitable idea than using aluminum as it may be cheaper and we can keep costs down for this econobox. But what about if theres constant abuse of spraying, does this material take well to something like that?

it should hold up BETTER than aluminum, as aluminum tends to rot when exposed to nitrous oxide.

Alum will get hot from heat soak. Nitrous is very cold when it is being released. So if you have a hot piece of alum. Say 115 degrees F (the hottest I have seen my IAT) the alum could crack from the rapid change in temp. Is that what you were going for tamago?

LOL thanks Garm i love that spelling too.... Yeah, if thats the case, why do they make the Hemi ones which takes a bigger jetting than a yaris would handle in stock form in aluminium. I dunno, all nitrous spacers are made from aluminium, i don't think theyd do it all willy nilly, if you want me to make it from phenolic, i don't care, its just general concencus

I don't think heat soak will be too much of an issue considering the TB is metal as well.

I think plastics would be a better material for these spacers, based on what I've heard... Cheaper, more resistant to temp fluctuations, and you can fabricate them using the same process.

I don't know about you guys but I just looked at my throttle body and I don't have an extra 3/8" of threads left on my mounting studs. The plate is 3/8" thick. I would have to find longer studs for three of the mounting points and a longer bolt for the fourth one.

Food for thought.


is there an answer to this yet?

cali yaris
06-05-2009, 07:52 PM
The correct length studs and bolt should be included with the spacer, and I'm sure they would do it that way so we don't have to source our own parts.

If someone could source longer studs for this until some are completed for testing, it would be appreciated, i will source some later on but those who have done it will already have the sizes and stuff. I know mikenacarato got longer ones for his, I'll PM him if he doesnt see this.

well i thought i would post in here to solve a potentiaal issue.

when i made my throttle body spacer i encountered an ongoing CEL that brought up a lean condition code. i dont exactly know the cause of the code but it could have been getting that much more air OR im thinking it was running a little hotter than usual. either way i put in injectors from the 1.8l 130hp corolla this past friday and drove to georgia for the weekend. i put almost 700 miles on the car with many starts and stops and went through both interstate and atlanta traffic...no CEL. problem solved. idles and runs perfectly. so if you put on a spacer and encounter this..here is a potential method to solve it. for those who wanna know about prices on the injectors...you can get them NEW at the dealer for 120-150 a piece. as far as salvage prices go..i have no idea..you would need to call your local salvage yard OR go to car-part.com to search for yards near you.

Mikenacarato, what sort of power difference did you feel? Also, with the 1zz injectors did you notice any change in fuel economy?

mikenacarato
08-18-2009, 01:10 AM
well i didnt really notice any power difference nor mileage loss. i did however notice the powerband was smoother and my cars idle does not bounce anymore. it used to sit at 700 then bog to 500 and bounce up to like 1200 then settle out again...and it wound do this every 15-20 seconds. now it sits at 700 and doesnt bounce

I sure wish we had a dyno on that modification. It would settle whether it makes any power.

$500 for injectors, one would hope it makes a little more!

What? Who paid $500 for 1ZZ injectors? They should cost around $25 apiece from eBay. I've go to read back a few pages.

I agree with Noogie... I found some for $25 a pop on FleaBay... Used, but they should work just fine.

And no, I won't post a link, since the seller only has 5 in stock. :biggrin:

tomorrow i will talk to him and see if he can make more and how much will be the cost i have to tell you he is not cheap but he make top quallity jobs maybe if we can make a group and i have to know how wide you want it mine is 1"
