As already mentioned - loose the intercooler clips and the car will run just like an N/A starlet.
Personally, I would've just drop an actuator - so easy to do and they would've never guessed why the car runs like a bag of spanners.
I hate giving my car to somebody else to drive, only to VERY trusted people, like my car mechanic for example! I feel like somebody is sleeping with my GF when I see someone else driving my car...
