Aristo VVTI Maf same as USDM Supra Turbo maf?
Does anyone know if the Supra Turbo USDM uses the same MAF? Buying a USDM Supra Turbo maf in the USA would be a whole lot easier than importing an Aristo maf from Japan/Australia.

^^^ What he said..
The toyota and denso part numbers are different between the aristo and GS/IS maf's, but I've seen on my.is were a few guys have successfully used the IS maf when thier imported motor was missing the aristo maf. And it seemed to have worked ok.

The answer to my original question is NO.
The Aristo maf and NA GS300 maf are not the same.
Sure your aristo swap engine will run with the GS300 maf sensor, but its going to run very rich.
Also, you would not want to use the GS300 maf housing as its going to make your aristo engine swap car run terribly rich as well.
Morale of the story, if you want to use the factory twins you should use the Aristo airbox, and Aristo maf sensor.
For those of you who are using a big turbo and you need as much fuel as you can get, this probably doesnt matter.

I stumbled upon some reading, and this seems to be true from what I'm reading, in my case I'm using the Aristo MAF, with the stock air box set up, and I'm still running rich, I even swapped in the stock MAF and the car broke up badly, dumping fuel like crazy ... Now I need to know get myself the Aristo air box

The difference between gs300 maf housing and aristo maf housing is .50 inches!!
By using a aristo maf and a gs300 maf housing your fuel calculations will be off.
I've ordered a aristo airbox with the correct aristo maf housing built in. I'm going to install it once I get back from vacation in about a week.
I'm positive now that I have the aristo after and aristo airbox I'm positive my cars going to lean out more and run better.

Wicked - cars running leaner now (still, very rich to my standards though) at about 12.5-13.5 on highway with light cruising. Its better than before with the USDM maf, but still too rich.
Ive put in a ARisto OEM airbox as well, and thats helped lean out the mixture because I think the difference in size of maf tube was throwing off the maf calculations.
Cars running great now. Ran a 13.5@104 at dragstrip the other night.
This is with: 4.2 final drive differential thats making the car shift too early and with open gearing!
Im trying to find a Aristo differential now to get better longer gearing and better traction out of the hole. Figure it might help me drop .2 seconds maybe more at the dragstrip.
Oh, and Im running fulltime twin turbo now as Ive disabled the sequential operation and upped the boost to about 15 psi (hits fuel cut at 16 psi!).
Other than that, cars running great and Im LOVING it!

Photos and update of the swap:

Car is running great, albeitly still very rich.
Bought a Supra Automatic LSD differential to lower the gear ratios and for better traction.
Sadly I can no longer drift around corners and burn out one tire as traction is far better now. I can solve this problem with more POWER though, hehe!
Bought a TTE replica lip and installed it unpainted. Also put on some 3mm spacers on the front and 5mm spacers on the rear.
Rear wheels BEFORE
Rear wheels after installing 5mm wheel spacers
Got tired of the traction lights being on due to the traction system not working with the ARisto swap so I removed the cluster and pulled out the bulbs for the traction lights. Presto, problem solved! Wahoo no more annoying lights being on all the time.
Next up- Im planning on swapping the JDM twins for the USDM Supra twin turbos to improve the power output. Ill more than likely have the turbos rebuilt just to make sure they are fresh, and Im considering putting in bigger intake side wheels for more air flow/power.
