You can add Nitrous. But that'* risky and you can blow the bejesus out of your motor.
Coils, plugs and wires. Only really noticeable if you've been driving around with bad coils, plugs and wires.
You can cam it and change the springs and rockers. But that'* a monumental task and you need to do other mods to get the full benefit.
You can change out the throttle body or increase the injectors. But, should also open the intake system for more air and the exhaust for more discharge. Then you'll probably want to do the cam, springs and rockers.
There'* no real single simple solution.
Start with intake and exhaust...open them up and let them breath.
