If I remember correctly the exige supercharger does not work for the celica since it was made to only fit the exige/Elise body. (It pretty much mounts on top of the engine if I remember) so there would be no room to close your hood. The greddy super charger is an excellent choice though and the apexi power FC would be a great combo with it.
ahhahaa...yeah smogging f/i celica here in CA is just a PITA. i sold mine. i'm not sure anyone here in cali is running a cammed 2zz on a stock ecu. you might have better luck with DD IM w/ throttle body for smogging ease.
