the car is going to be a dd still and i live about 3 hrs away from phx so the goal is for a nice reliable street/track car! i dont have e85 around here so pump gas is the only option. the cosworth is what im wanting to get just because i havent heard of anyone say anything bad about them. But asu you have a good idea.... i might just get some head work done since it torn down anyways right? how much of a power gain would i actually see on pump gas?
