If you believe it with all your heart and mind, and recognize that when Jesus died He did so to take all your wrongs, all those acts against the will of God's righteous desire for you living your life as he directs, upon Himself on that last sin altar, the cross, no. There is no thing else that is needed. Repent of your sins, hold faith they are now under the blood Jesus shed so as to cover them, pay the debt owed for them to God, so that you are now reborn as a new creation in the body of the anointed, Christ, and you are healed.That Jesus shed His blood and died for me on the cross and that He rose from the dead the third day?
Is there anything else that would need to be believed for salvation?
