is there a supercharger for a 2005 2.3L mazda 3
 

Just curious if there was one out there. I will go with a turbo but i don't usually drive in the high rpm ranges anyway.

Nope, no supercharged Mazda3 of any stripe from the factory. Why would you want a supercharged engine anyway? With the exception of speeds from zero to about ten, the turbocharger is superior to a supercharger in every respect.

A company called F2 racing had a supercharger kit for the mazda 3, but they had either moved or closed down. It had made some good power on 5psi and it was a "procharger".

Agreed with the above. Basically you have to build a universal procharger kit and run about 5psi on stock engine/ auto tranny without destroying it pretty much
