The throttle body adapter to allow the 2005-2008 base model vibes is still being made by Carver via estranhoATaolDOTcom
I'm not 100% sure on this, so I'm hoping some other dudes will chime in with any necessary corrections, which I can quote into this post:
The adapter is so that the TRD supercharger can fit the drive-by-wire (DBW) throttle body; the '03 and '04 models used drive-by-cable throttle bodies. I think that this also allows AWD base Vibe, MR2, Corolla, and Celica GT to use the TRD S/C. You will still need aftermarket piggyback ignition/fuel control, and I know for sure Celicas need an aftermarket hood.
Oh, and I guess the MR2 Spyders with the 1ZZ-FED engines with DBW as well, (do they have DBW? Dunno)
