Quick question, do you happen to have a part number for that 1zz throttle body? I'm looking to install into my '09 Yaris hatchback, to complement my other mods (K&N cold air intake, Blitz supercharger, DC header, Magnaflow catalytic converter, and TRD exhaust).

Thanks!

Do you plan to port your intake manifold? The stock TB gasket won't stay put or seal with the 1ZZ body, if I recall correctly.

If I recall correctly, it worked find for me. I just used some silicone gasket maker around the new throttle body just to ensure an airtight seal.
I might have did away with the stock TB gasket...this was a few years ago, I don't recall exactly. XD
