2013 Mazdaspeed3...Need help with fuel setup

How's it going, I've got a 2013 mazdaspeed3, bought it with an injen Sri and a butchered exhaust. I also have a cobb access port with a purple drank tune pushing 20 psi. I don't know how much power I make but my goal is to make 450-500hp but the only issue I have is that I don't have anywhere near me that sells e85.

I have seen someone make 500+ on 93 so if anyone can help me on the parts I need for the fuel setup and where to purchase I'd like some help on this.

I've asked several companies and even experienced mechanics on the platform and I have gotten no reply.
