Electric supercharger 5 psi vortex for Celica

i have a 2000 toyota celica gts and im wanting a little bit more power but i dont have a lot of money and i say this electronic super charger online for only $200, could i just bolt this onto my celica or would i have to rebuild the engine or do anything like that to make it work? and has anyone out there already tried this and if so how well does it work? here is the link to the website i saw it on http://www.performancechiptuning.com/Electric+Supercharger+5+PSI+Vortex/10/
