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.

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...

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'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 · 10-28-2012, 04:37 PM

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 · 10-28-2012, 08:53 PM

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.

tooter · 10-29-2012, 12:00 AM

I believe it was specifically manufactured that way so that just one MAF tube would be able to fit both the 1NZ and 1ZZ throttle bodies.

Pretty clever idea, actually.

It just occurred to me that you could use your K&N with a 1ZZ throttle body. All it would take is a 2.25" to 2.5" silicone adaptor with the larger end put onto your throttle body.

ljming99 · 10-29-2012, 02:34 AM

My memory is probably quite bad, not sure if the original tubing is hugging the battery.

Any issues there? i see from the picture that the grey tubing is up against the battery.

tooter · 10-29-2012, 12:24 PM

The tubing touches the corner of the battery because the tooter manifold relocates the throttle body a couple of inches to the right. However, it doesn't cause any problems as there isn't enough pressure on the corner to kink the tubing.

tooter · 11-09-2012, 06:37 PM

The first run of redesigned adaptors is done. The advantage of these are that just one part works for both the 48mm 1NZ FE throttle bodies and the larger 51mm 1ZZ FE throttle bodies...

There was a clearance issue with one of the hex head bolts and the larger diameter throttle body gasket. The solution was to simply reduce the diameter of the head with a grinder...

The larger 1ZZ FE gasket fits perfectly. Just finished bead blasting, and it's ready to install on a manifold.

CrankyOldMan · 11-09-2012, 09:13 PM

Again with the car pr0n! Looks great, too!

Bluevitz-rs · 11-09-2012, 09:29 PM

Have you done a test fit yet to make sure the 1NZ TB seals properly on the car running?

Not yet, as I just got the adaptors this afternoon...
The 3mm larger diameter O ring gasket means a perimeter radius difference of only 1.5mm larger all the way around which isn't a lot.

The 1NZ FE throttle body base has a much larger flat area on it's base than that. I'll be running a new adaptor this coming week to confirm that everything works.

4/20 NEVER FORGET · 11-10-2012, 07:36 AM

I'm very interested to see if this makes power with the 1zz throttle body, which it should.

Keep up the good work!

tooter · 11-12-2012, 11:27 PM

One tooter manifold with the redesigned adaptor adapter is now complete...

Now just one 51mm bore adaptor plate fits both the 1NZ FE and 1ZZ FE throttle bodies.

The tooter uses all of the stock Toyota head bolts, studs, and nuts, and the stock Toyota O ring manifold gasket. It uses a Toyota 1ZZ FE throttle body O ring gasket which works fine with the smaller 1NZ FE throttle body, and uses all of the stock throttle body studs, nuts, and bolt. The manifold flange is hand clearanced fit to the head perfectly and simply drops right in.

Not too bad for a wrecked dirty 14 year old junkyard part.

It requires the intake to be shortened because the throttle body is repositioned about 2 inches to your right as you're looking at the engine from the front of the car.

4/20 NEVER FORGET · 11-13-2012, 05:51 AM

Looks great! When is dyno day?
