tooter's manifold adventure...

[tooter]

Yes... you're the first.

[tooter]

All of the tooter manifold flanges are done now so I can start putting them on the manifolds...



The manifolds are all in various stages of being cleaned. They all basically looked like that dark dirty one as they're 14 year old junkyard parts, many from crashed vehicles. They all have scratches and dings, but look pretty decent when they're all cleaned and blasted.

With the flanges done, the machining on the adaptors will be starting when I get these larger gaskets so that the adaptor design can be altered to fit them.



This Corolla gasket is larger then the Yaris one and allows for a 51mm bore. I decided to make just one adaptor which will fit either a 1NZ FE or a 1ZZ FE throttle body. This will allow for an easy upgrade without needing to change anything else.

wait... so is this your next venture? making a corolla xrs manifold fit the yaris? dooood!

I doubt it...
I still don't have a completed 1ZZ manifold yet, as the newely revised adaptors are still in the process of being machined. So far all I have is the running prototype on our daily driver. It's interesting that others have been doing the same manifold adapting idea.

[tooter]

Finally... one completely finished manifold...
The bead blasting put a nice low luster finish on it and made the welds look a lot better by making all the surfaces take on the same evenly blasted texture. I even blasted the adaptor so that it now has a matte finish similar to the throttlebody...









Tooter #2 one now becomes the daily driver tooter because it had the worst dings in it. They're only cosmetic and are barely visible when looking low from the front, but it's still not fit for sale so I don't mind keeping it for our own use.

I'm still waiting on the adaptors which should be ready any day now. Tooter #3 is ready for the welder, and tooter #1 is going to the blaster.

Damn, that's sexy! It's like car pr0n...

[Viperoni]

Looking good!

[b20vteg]

sexy!

I bought a Simota intake from Buddy Fan (Thanks, Buddy ) shortened and bead blasted it to match the manifold. And am waiting on a silicone adaptor to finish it off...



Test fitting it into the throttlebody...

[tk-421]

That looks a lot better than before. The only concern is that the sensor is now a lot closer to the filter. Hopefully that won't cause a CEL.

That's just a test fit. It'll be a couple of inches farther away from the MAF sensor when the silicone adaptor coupling is installed.



The aluminium tube is 2.25 inches and the filter is 3 inches. There's plenty of room to move it out farther.



For all the crazy experiments I've tried, so far I've never gotten a CEL light.

[tooter]

The silicone adaptor came today less than 36 hours after I had ordered it on ebay. That's speed of light shipping. So now the intake is ready (plus one more clamp) to install on the throttle body tomorrow...

[4/20 NEVER FORGET]

I'm excited to see how the manifold performs with a 1zz throttle body. Good work on keeping this project going!

Also, is that a Simota intake tube for Yaris or for another car? The tube diameter looks larger than the 1nz throttle body. I am using a k&n intake right now and the throttle tube size is nearly identical to the 1nz throttle body diameter, so I knew in the future when I swap to a 1zz throttle body I was going to have to get an intake with a larger diameter tube.

I remember reading something on here something saying that you couldn't go over a certain intake diameter because it would cause the MAF to throw a cel.

The redesigned adaptors should be done this week, and I''ll be picking up tooter #3 from the welder. So everything is progressing nicely.

It's for a Yaris. The tubing actually flares out to a larger diameter only where it connects to the silicone coupling at the throttle body...



...but is 2.25 inches at the MAF sensor which is the same as the Weapon R intake I've been using...



The Weapon R flares out to 2.5" in front of the MAF sensor while the Simota remans at 2.25" but then flares out to 3" to fit the air filter.

Yes. The K&N Typhoons are straight 2.25" tubing all the way through to the air filter. You raised an interesting point. To use the same MAF sensor with the 1ZZ throttle body, the MAF tubing section will still need to be 2.25" for it to work properly. But there are lots of intakes that go to larger diameter tubing in front of the MAF section, so all you would need is a silicone coupler to fit. The Simota appears to already address this situation as it flares to 2.5 and uses a reducer coupling to fit onto the 1NZ throttle body. If it was used with a 1ZZ throttle body, it would use a simple straight coupler.

I remember reading something on here something saying that you couldn't go over a certain intake diameter because it would cause the MAF to throw a cel.

I've tried a few different intake configurations, but all of them are with the MAF tubing section at 2.25" and have never gotten a CEL light. So the front side of the 2.25" MAF section can be almost anything else.

[tooter]

Got the intake mounted and it fits fine...





Next comes the test drive. (oooh, goody )

edit: The engine runs great... and no CEL light.

[4/20 NEVER FORGET]

I see, thanks for the explanation. That's weird that the intake flares out right before meeting the throttle body. On the K&N it does not flare out so it doesn't require a reduced coupler.
