GI: 1nz/1zz TB spacer

[Nexus1155]

Hey guys, I had some confusion with the CNC machine place with the ordering of my machine, i fixed everything out with them and they're coming to setup the machine in my basement soon.

Thanks for the update we are all eagerly waiting. I got my custom hub spacers now i need a throttle body spacer.

don't worry, pieces to the CNC are already coming in the mail everyday, today i got the computer unit and the motors, yesterday i got the DRO unit, it should be getting drop shipped soon!!!

I'd be interested in one, as long as, my warmup idle doesn't raise anymore than 3K rpm.

i didn't read the whole thread but i didn't see this mentioned in the first few posts.

what material are you making this from?

this is a spacer, not the throttle body swap

Aluminium.... why? lol

^ I like the English spelling version. My vendor in India spells it that way.

if you want optimum performance, make it from phenolic

[cali yaris]

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.

O.K Spock LOL.

so, garm, you can cut and paste!

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

[Nexus1155]

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.

[lilredrocket]

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?

[Nexus1155]

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

[PHXDEMON]

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

[tk-421]

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.
