FC3S = Time Bomb
FD3S = Fire Trap

I vote for the FC3S. Just make sure that the engine has been well maintained. Be sure to double check the apex seals and the condition of the turbo if it's a Turbo-II. FD's are horrendously more expensive and not really worth it IMO. Besides, FC's are much sexier.
