@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?
Sorry it took so long to reply. Out front EJ25 basically has better heads and different ECU. This will provide higher compression which will allow you to take advantage of premium fuel. I doubt a stock EJ25 would benefit from premium fuel. I apologize to Carey if I’m incorrect but Carey rebuilds the heads but I’m not sure if he adds any performance modifications. I think the engine is stock and obviously he uses the stock ECU. That Suby engine with a restrictive exhaust system and a cat got 165hp. With the less restrictive exhaust the Beck Spyder is likely about 175hp. Even if Carey builds the heads, without a different ECU you won’t get much more than 175hp. I’m sure the car is very fast with 175hp. Stupid fast? I don’t know. I know mine is pushing at least 200hp and sings to 7000 rpms. My cars in Charlottesville Va if you want a ride.
Carey has his recipe for success and it works very well. I think he leans toward dependability. I’m leaning that way with my 356 type D build and Carey will put a stock EJ25 in that car.
