Sure, man.

I'll swap you straight across for a spacer as long as the tooter kit is unused. I'll pay the shipping to you if you pay the shipping to me. I have a Corolla manifold sitting in my shop that I need to build, and it'll save the CNC engineer the time to make another set.

How can I get one of those tooter adapter.

I'm really thinking about pulling the trigger on this and trying it on my 1NZ-FXE.. Should bolt right up.

If your intake manifold looks like this...



I have no idea as to the spacer's effect on your engine...

However, it would be an interesting experiment because you have an Atkinson cycle engine and not an Otto. You'd also need at least 3 inches of free space in front of the intake manifold for the spacer to fit. From the drastically shallow design of that manifold it looks like free space might be at a premium. But I don't know your under the hood situation. Can you post a pic of the space in front of your intake manifold? Then you can go from there. Don't get one without first finding out if it would even fit.

DOOOO EEEET! Dyno runs or it didn't happen!

[tooter]

The only issue I can see is that very strange 1-2-4 (opposite of a 4-2-1 tri y exhaust manifold) intake manifold is specifically designed for an Atkinson cycle engine and is tuned for a very specific optimal rpm range. So an intake manifold spacer lengthening those extremely short intake runners is likely to push the curve outside that range. While there's a chance it might make it better, there's a greater chance of making it worse.

First off, thanks to Greg and Garm for all the fun stuff for these engines. Wondering about matching a spacer up with my dated Weapon R manifold. Greg, even if Malibu Guy's Tooter is used I might be interested. I also have a spare Corolla manifold that I've been meaning to "Tooterfy" so either way.

Thanks, Ken

Mine isnt used but it is...if that makes any sense

The last tooter I sold on ebay was listed in the category of "remanufactured" because it was a combination of old and new parts that were made into different product.

If this spacer is a hit I think someone needs to make a replacement engine cover to go with it

Hey wait a minute... that intake doesn't look stock. Did you make a custom CAI for it?

There's an experiment you can try...
Unbolt the 5 bolts holding the intake manifold, yank all the hoses and put them out of the way, and then measure how far away from the head you can pull the manifold before anything hits the plastic reservoir of anything else in front of the engine. That will let you know whether or not a spacer will work. To me it looks tight in there, but it's hard to tell from pics. You'd know better than anyone else because you're right there.

Any update on the mileage?

I filled up once so far after installing the Tooter spacer. You can track my mileage here:

So far, a slight increase in mpg. A bit too early to tell though.

[Kaotic Lazagna]

Just filled up this morning, however it's missing about 30 miles of city driving. So my last two fill up's are with the Tooter spacer.

[tooter]

Thanks, Laz, for posting your gas mileage results. They're more credible coming from you than from me.
It took a while for me to find out that the spacer allows the engine to operate just fine at lower rpms (1,000rpm to 2,000rpm) without any strain or lugging...

...even though my wife still revs it up.

No problem. So far, three tanks with the spacer on now. Something to keep in mind is I don't know if my local Chevron has switched back to summer blend or not. But if comparing to around the same time last year, it's a 2-3 mpg increase.

3/22/13, 318.8 miles, 7.92 gallons, 40.2 mpg, $4.060

vs

3/20/14, 340.9 miles, 8.06 gallons, 42.3 mpg, $3.940
3/25/14 313.0 miles, 7.17 gallons, 43.7 mpg, $3.940
