GI: 1nz/1zz TB spacer

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.

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?
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.

Also depending on price I'd be interested.
You may want to post up what mods are required for this mod to be installed, so that stock cars can get in on this. Has a prototype already been tested?

[PHXDEMON]

I am for sure down for the port matched 1zz tb to 1nz manifold spacer.

For the factory engine and throttle body i would be very interested in this. Strait bold up without having to deal with check engine light. I supose a reasonable amount to pay i would say 50 dollars. Also would be interested in powdercoated in different colors such as red. Please keep us posted im bookmarking this thread.

No other mods are required for this, someone with a completely stock car could put this on.

When do you estimate you will have some ready for sale and what will be the cost?

[AlexNet0]

I am getting the proto back sometime this week. Ready for sale depends on amount of sure fire interest, After we test it. After testing Nexus is either buying a milling machine or we will have them sent to a machine shop for the first batch. I will not know the price untill then

[yarstar]

Thanks Alex. Call me a "Sure Fire." I'll be looking forward to reading your posting of your R+D results.

What are we predicting the gains will be with this spacer?

Lets make a list to help encourage this

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]

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]

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

[whooppee777]

i'm definitely interested in a spacer WITH the port for the nitrous fogger

[tk-421]

OK I guess I'm interested in one with the fogger as well.
