R34gtt Gearbox Manual

[R34P3R]

hey all ive noticed that when changing gears that its not that smooth. my friend just bought a r34 and his gears when changing is smooth. mine changing from any gear to another isnt bad but you can feel when its in neutral and then the gear, friend car you can feel it but you dont really notice it. is there anything i can do to try and make mine smooth again?? is it my clutch coz a few friends said it might be or is my gearbox starting to die? could it be my sync? ive read before that these gearboxes sometimes arent in sync and crunch when changing, mine does that at high rev.

please post your opinions on what it could be. tried searching but not really sure what to search for
