Intake Manifold

[ttr125fan09]

What need to be modified on the XB manifold to fit on the yaris?

[thebarber]

replace the throttle body mounting flange (xb is 3 bolt, yaris is 4 bolt)

the angle of the intake/throttle body mount is different, so you'll want a short ram intake (vs stock or cai)

I have actually seen one on an xA this summer.....nicely made piece,spendy....but nice.

from what I could see the plate just needs cleanly cut off with like a bandsaw or chop saw for metal....and any good shop that tig welds....think outside the box....motorcycle shops.....can make a new plate out of SS sheet and drill the new holes and tig it back on...it looks very doable.

What im doing for the custom intake mani from the NOS Yaris I bought is using a Matrix TB spacer and having it welded on, then just bolting the Yaris TB up. Its basically an adapter. :thumbup:

Hi jekqmb. Any pics of your intake manifold?
Thanks... :smile:

Here it is, I bought it from Jay. I will be posting pics once i get the TB spacer on it and send it off to get powdercoated.

Here it is on his car from last year!

Any plans for a dyno session?

Yes for sure!

[sito]

Thanks jekqmb. :smile:

Got the manifold today! Looks really good, here is another pic, lemme know if you want any other angles of it! Im getting a Polished TB adapter welded on Monday then the Mani is getting painted Dark metallic Purple Tuesday, then its going on wedsnday.

[thebarber]

isnt that manifold really only good for a turbo application?

[jekqmb]

Ya the XB one from weapon r is i heard, there is a guy here in st.louis using one na on his XB and only gained like 2whp.
Ill keep you guys updated on the one i got, i will be using it with nitrous. I wrote a review on Microcarmag.com about it, so follow along!

Could you do me a huge favor and measure the openings and their spacing? I've got a corolla intake manifold that I'm going to modify for a 1.8L throttle body (like in this thread (http://www.yarisworld.com/forums/showthread.php?t=36723)). The corolla openings are 35 x 52 mm and they are 87.5 mm apart.

[jekqmb]

Sure will do! Im actually working on it right now sanding the old poopie paint off to prep for powdercoating!

[CrankyOldMan]

Thanks! I did a bit more searching and found that the cylinders are 75mm dia. and 8mm apart, so the spacing should be 83mm. Just need the opening dimensions and the bolt locations and I can get a CAD model rolling.

The short runner design may produce some high-end power, but the torque will probably suffer.

The Weapon R one has longer runners but a poor plenum design.

Yes for sure!

Do you have a before dyno?

Yea i do i need to find the sheet, i have to go digging for it! haha

So you need the inlet size and the bolt locations?

[CrankyOldMan]

Sorry, I think I was a bit vague and/or don't know the right terms. I need the size of the four openings that mate to the head (inlets?). I'm assuming that they mate 1:1, but if they're different than the actual openings on the head, then measuring those would be even better. The openings should have circular sides, so those should be pretty easy to measure. I'm not sure how you'd go about referencing the bolt hole locations though.

Thanks for your help with this!

Ok ill get them for you! :thumbup:

Just visited Micro Car Mag... Interesting. I'll have to be ck'n it out samore later.
Enough OT. I'm interested in what the head intake port dimensions and spacing are also.
I'm currently working on an exhaust header for my Yaris and hope to have something everyone looking for street performance would be interested in also. Ultimate track perf is another deal, maybe I'll get there later. The original exhaust manifold is such a joke there is little need to modify anything else first. I like the idea of purchasing the Weapon R Intake and modifying it for the Yaris, if that's the way we have to do it. An intake is alot of work compared to a header. Tunning and testing will take a while. Actually the stock intake is quite nice just a little on the small/long runner side for high rpm performance.
These are the 2 most likely components to bring good butt dyno, street performance results without further mods forced intake and piggyback ECUs etc.. But, as you can see we are being left out the cold by manufacturers. A 1 3/8 tube 12inch primary pipe header as Megon and others produce is Buls$%^t. A NA intake like the weapon R is not the best either for the everyday driver balancing MPG and foot on the floor performance. Maybe I can fill the niche? :biggrin:

[CrankyOldMan]

I'm interested in what the head intake port dimensions and spacing are also.

I found a document that listed the cylinder bore as 75mm, and the wall between cylinders as 8mm--making the cylinder pitch 83mm. As far as the opening dimensions, I still haven't heard anything back on either recent intake manifold thread. I'm hesitant to pull off my intake manifold since it's my DD, but I'm thinking about putting on my 1ZZ throttle body soon, so I may do it then.

Why wouldn't it be posted right here?

[cali yaris]

That's not true. No one has ever been able to get ten serious buyers lined up for parts like this. I mean deposit-down kind of seriousness.

I've offered many times to make the parts -- the market isn't there for some of the higher priced items, when you include design, prototyping, testing and production.

I would love to be wrong, so go for it. :smile:

The thing is there are several companies doing products for the Honda's etc. Doing 1 or 2 more for another model is not that big of a deal for them already having the manufacturing and distribution set up. To get started doing your first is the big hump to cross.

[cali yaris]

There was very little support for the Hondas in 1981, when it was also five years old. I think it's an unfair comparison to the Yaris.

[CrankyOldMan]

So did you manage to get this installed yet? I'm still struggling with the end bolt hole locations, but have the middle three pretty well sorted out.

[Performance Pro]

Here's one 499.00

You tell them what T/B flange and year make and model a whola all done!

TBR and Golden Eagle

And their available along with new billet fuel rails! Looks like TBR and Golden Eagle are setiing the Pace for others to follow.

[Parmas]

I think there are too many upgraded parts for the 4EFTE Toyota starlet engine. If the manufactures will understand that our 1NZFE is a better performer (which in fact it is) than they will surely shift making the same for us!

[Performance Pro]

You can even send your blow-by out to this cool valve cover which is already trimmed out for a new after market fuel rail! Someone out here is thinking of the 1NZ-FE

[flg]

The manifold looks very impresive. We are begining to have some choices. Care to give dyno pull results with a stock motor header and good exhaust? I'm not sure we've seen that for the Weapon R counterpart but it is an alternative. :biggrin:
