I wanted a stupid fast Spyder and that's what I got. So if your car needs to be stupid scary fast the stock EJ25 with the stock ECU will not be enough.
@550 Phil Carey will build my 550 next year or so. My current Alfa Romeo 4C does 0-60 in 4.1 sec., and I want the 550 to better that. The 4C is 237hp pushing 2400lbs, so the 550 should do better if the tires can hold on. BUT, I hear you, and I want mine to be scary fast too. So, what should I be thinking about changing? Is it a different EJ25 from what Carey would normally use, or just some different parts there? Or different ECU? All of these? What would you recommend?
