I'm guessing 92ish? I'd like to try this on the emanage.
Maybe it's a cultural thing? I mean, we saw the British coming. India, they did not.

Yea 92ish. Turbo mr2s have that same iat sensor on the engine lid. Car uses it to turn on the intercooler fans. I also used it when I wired the stock 3s harness to run the newer gen ecu that uses map and iat.

Disco mr2 is same as Gte gen 1 that screws into the intake? Or as the corolla style that's plastic and is designed for the intake tract? Gameface I believe just wired in a gm unit and said fuckit.

Usd mr2 was always maf so it only had the plastic one as a thermostat for the intercooler fan. The maf had the iat for the ecu built in. The 3rd gen and on 3sgte used the 2, the screw on one on the manifold and the plastic one on the intake. Dont know why Both. But they both use the same resistance across different ttemps.

Bumping this. 

Has anyone used the stock IAT and just welded a bung for it into the FMIC piping? 

I have greddy emanage ultimate and I'm trying to figure out if i should go GM IAT  or try to find a ???M16 x 1 . 5 ???? bung for the stock IAT?

An AIT is an AIT......

It's just a thermistor.

Back when HKS VPCs were a big seller, I was making my own using thermistors from an electronics house, and a machined phenolic/aluminum housing.

 

But just about any Toyota one should work.

And the HKS IAT has a very small M6 thread, and I think are just $60.

The one I have is too fuckin big. And I hear the GM IAT one reads differently. So not sure how an IAT is an IAT unless I misread.

It may.

But if dealing with a stand-alone, it doesn't matter, as that is all definable.

If dealing with an oem ecu, just have to check resistance at freezing (ice water), and boiling water.

Or as I suggested, just use any Toyota unit, as they are most likely the same range.

The old 7M flapper meters have one held in with a single screw, and quite compact.

You could buy a m16 to 1/8 npt adapter. I bought an AEM 1/8" NPT AIT. It doesn't nearly stick out far into the air stream. I also ended up over tightening it and snapping it in half.
