You will need to lower your compression and upgrade your fuel system. What type of fuel pump are you running? That's just a start.

What fuel do you run? I understand you don't want to cross the line from
A street car to an all out race car, if you want to have fun on the street you need to lower the boost.

either lower your compression with new pistons or have fun with your setup for this year and do it all next year. I have seen some people including myself run that setup. I had ran 5 gallons of 110 and 5-7 gallons of 93 and upped the boost to 7-8psi. I ran it like that for the entire summer. So it can be done BUT I knew if it blew it up I would be ready.
