Custom Intake manifold! - Toyota Yaris Forums

monchyxb · 10-12-2011, 02:54 PM

I just bought a corolla 2000 intake manifold with the flange made for the 1nz. Also adapted a corolla 2zz throttle body. Did some powder coating and mounted it today! had to improvise for the moment with the vacuum hoses but I will fix this tomorrow... right now I wanna test this! here are some of the pics.

result should be interesting - no-plenum design

What's the throttle body flange inner diameter? I've been thinking I want to try and fab up my own to get the full 1ZZ tb diameter instead of necking it down to stock.

I think its a little bit more than 2.25". Huge response when going WOT. If you want to do it you'll have to make a custom flange since the throttle is 4 bolts instead of 3.

Crap, I knew there was a catch! I thought there were some drive-by-wire TBs with three bolts, but looks like only the cable driven ones have 3. Does it look like the end of the plenum could be cut off and re-welded with a new flange? The only pic I could find online was a side view that doesn't show the TB port.

Yes you could cut were the throttle is bolted on and make a flange for the other throttle and weld it. It has the space to do it! Or you could use the throttle that comes with the manifold which is bigger than the 1nz.

The yaris uses electric throttle control (DBW), not a cable like the xB. There are plenty of 1.8L throttle bodies for the 4-bolt pattern with DBW, but none that I can find with the 3-bolt pattern and DBW.

Cool! Is this a one off or is someone making these?

cali yaris · 10-12-2011, 07:19 PM

thread should go in Performance Mods, no?

netz2008 · 10-12-2011, 07:25 PM

Wow, drive by cable? Second Yaris I know that uses that!
I've got the 1zz throttle body, and my intake manifold is ground down to the diameter of that throttle body (big difference between a stock intake manifold and port matched btw)

Bluevitz-rs · 10-12-2011, 07:34 PM

^ his "Drives:" is an xb so why wouldn't it have a throttle cable?

monchyxb · 10-12-2011, 08:58 PM

People here in Puerto Rico are doing it for the 1NZ.. I have seen a couple on a classifieds web page from here.. I bought it for 150 from a guy who claimed around 8hp on an aspirated motor. I felt more power just bolt on, but some A/F problems at idle the motor turns very lean so next week I'm off to the dyno to do a tune and see the numbers.

BTW how do I change this to performance mods??? Sorry noob here!

cali yaris · 10-12-2011, 09:44 PM

Even if it doesn't make much power, it's sexy as hell; I'd rock that.

From Mayaguez! 50 bucks sounds nice.. but the expensive part here is making the flange to make it fit in our motors, The guy who I bought it from said it cost him 100 to make the flange :/

CrankyOldMan · 10-14-2011, 08:59 AM

Ok, found some info on the 1ZZ.

* 87.5 mm cylinder spacing.
* 41 x 413 mm runners

I measured the flange on the manifold and found that the runner spacing is also 87.5 mm, and the ports are 35 x 52 mm elliptical.

Update:

I found some info on the 1NZ cylinder spacing:

cylinder bore: 75mm
cylinder wall thickness (between bores): 8mm
cylinder pitch: 83mm

That should make the header pitch 83mm as well. Now to figure out the opening dimensions and bolt locations...

Maybe that type of manifold works better for boosted cars than N/A, I had a buddy of mine (with a B.Sc in ME, built an IM as a part of his schools Formula SAE team, and worked for GM) tell me that it's tough to implement properly on N/A cars and a typical runner+log manifold works better.
