1zz Tb on a blitz supercharger ... Any good ?

[CrankyOldMan]

While waiting for my engine to cool off enough to change the oil yesterday, I installed my injen CAI. Some interesting things to note:
* The stock throttle body is TINY compared to the 1ZZ.
* The injen intake isn't a suitable donor for a 1ZZ due to the diameter of the mating end and the limited space to clamp a silicone coupler near the MAF mount.
* Finding an inexpensive aftermarket intake to scavenge a MAF section from is difficult, now that the Simota is not readily available.
* Finding an off-the-shelf 2.25" MAF section is pretty much not going to happen.
* Putting an intake on a supercharged engine makes for some really silly noises.
* There is a LOT of room to get creative in there, provided you can do all the silliness where the OEM intake was--not much clearance at the top of the S/C.

Correction: this may be a suitable alternative source for a MAF section, assuming you can deal with a 3" body:

You could hack up this eBay intake kit for the MAF housing - verified its 2.25"

I tried the Spectre 3" MAF - immediately threw a CEL - MAF out of range. Unless you can modify this setting with the ECM - 3" is just too big for the 1.5.

Now, that is one hell of a deal for only 44 bucks and free shipping!



It's well worth it, if only just to get a MAF section.

Agreed, it's a great deal for the tube. The rest looks like junk. Went ahead and got one.

And save the other pieces...
With careful cutting and straight silicone couplings you could create any custom shape intake you wanted.

edit: Just checked the seller's feedback and couldn't find any negatives for that intake. And they sell at least 2 of them a month.

I don't see any info on it being 2.25. Did you verify it yourself, or are you saying "if it's verified"?

Was that with the 2.25" 'calibration tube'? Was it by chance P0103? I threw one of those today when I went through a rather deep puddle and splashed the filter. Scared me pretty good.

glancing through the thread, the MAF discussion caught my eye. the K&N typhoon intake's ID matches the 1ZZ TB ID, and does not get smaller at the MAF spot. they overcome this by putting a small little piece of metal in front of the MAF at an angle to fool it into thinking it's the proper diameter. (i bet if we harass 4/20 never forget, he'll take a photo of it for us!)

Yes. I've seen that strange metal "ramp" on a K & N Typhoon intake. It's a creative adaptation.
