I'm wondering if I can't take the individual throttle bodies off an MR-2 or AE86 and put them on the Yaris with a custom bracket and throttle cable.

Drive-by-wire sucks.

Physically adapting ITB's wouldn't be insanely difficult, but making them work would be.

N/A mods will leave you broke and underwhelmed. With the amount of money it would take to get the car into the 16s you could buy another car that has potential to go fast.

Drive by wire sucks when it seems like it is not listening to 100% of your commands or if it is delayed. The truth is that drive by wire has the potential to snap open the throttle faster than it would if it was cable driven.

Its one of those things that could probably be flashed into the ecu.

Fitting ITB's won't be a problem, Dan actually sells a premade "kit" for this:

You can either remap the ECU to accept the mechanical throttle and TPS signals or you can swap ECU's to a standalone (TEC3 on the scion above) or run the OEM Toyota AE101 or AE111 ECU's.

Keep in mind all of this won't do much for power, believe the red Scion only makes ~130 crank HP, but they did this more for the looks, sound and they are now planning to turbo the car.

If your plan is to go N/A on this engine, the easiest way to do this is to pick up a spare junk motor for under $500, then experiment with cams, and valvetrain, since that is where the biggest restriction is. You can then bump up compression and with beefier rods/bearings/pistons raise rev limiter and making some more top end. I would budget somewhere in the range of $4-$7K for the engine alone.

remap the ecu? How in the world are you getting around the fact that you are tossing the MAF sensor out?

Many modern computers can operate on as few as 2 of the 5 inputs they originaly contain. Using techtom software, several tuners can "teach" the stock computer to recognize MAP sensor voltage readings instead of MAF readings. It's a simple 0-5 volt sensor and as long as the maps are correct, the effect is the same.

I'm not saying this is the optimal setup, and most times, if you're going to the trouble of all these mods, You'll likely run an aftermarket EMS setup, but it is possible and people do run their cars like this.

How in the world is a map sensor going to work well with no intake plenum.
I know that electromotive used to make a complete aftermarket ITB and ecu setup for the Dodge Neon.

After reading that above listed link I don't think anyone is going to want to drop any money on n/a mods.

The question of the hour should be what motor can be swapped into the chassis. Hopefully some company comes up with swap mounts for the Celica motor.

As long as there is a vaccum reference it will work just fine. In the old days we ran alpha n which in iself is the most primative way to control efi.
Let me add that forced induction is the best way to make some ponies and still maintain great driveability
