Going Turbo and Premium Gas

[WHATSaDavid]

So I eventually wanna turbo my 06 yaris 3-door.
Not looking to push mad boost or anything just enough to see some horsepower improvement and be choo chooing XD (I love how they sound)

My one question is i've been told by my buddy his STi can't run on anything other than premium and that all turbo car's have to run on it. I've read elsewhere that some manufactures make specific turbo cars to run on 87 or regular, so I know what he said isn't completely true.

I'd like to turbo my car but if I'm gonna have to get premium I might not do it cause gas is pretty outrageous here in Canada, Alberta. $1.08 for regular currently. Sometimes as high as $1.40.
