For the MP4-31, you can only get the Custom Racing Engine card randomly from boxes or from boxes given in its Championship: "Grants X cards for the McLaren MP4-31"

As for the FXX, it'll be your credits grinder until you can afford the Veneno. Once your Veneno is at Max Pro, its 15th Mastery is your new grinder for the Lykan.
