Wow, take a look at the Celica forums. There are several supercharger kits already available for the 2ZZ-GE engine. I'm sure somone will get around to adapting it to the Elise. Looks like the most radical kits will be putting out 300HP/ 230ft-lbs. Yikes that'll provide motivation for the Elise. Might be worth the 75-100lbs.
