Man unles you plan on runnin race gas in the 3zz with the 13:7:1, it aint worth all the money(at least no to me). So much compression, you need to run it with at least 110 octane fuel all the time
Actually, you'd be fine with 100 octane...
Besides, anything higher than 100 octane is NOT street legal, since higher octane levels will only appear in leaded fuel, which you can't run on the street anymore.
EDIT: actually, I think there are now a couple of sport compact formulations that have higer octane in unleaded formulas, but they only approach 108-109 octane. Either way, racing fuel is expensive.
