It runs on Regular, unless they've advanced the timing with a chip, tuner, or timing adjuster.

You’ll need 100+ octane AvGas for a GT FYI. However I recommend buying and installing a Tornado. With a Tornado, you will get better gas mileage than a Civic. I’d also recommend investing in a Turbonator for added power…

i think i saw a stickey saying not to buy a tornado b/c it doesnt help and it might have also decreased mpg and hp. I wish my car took regular.
