I got it my car not to long ago. Pressed the pedel down to start the car and felt a "pop", ignored it. The car starts and I put it in gear but when I releease the clutch it feels different. Like a shuttering feeling when coming back up. Now when in 5th gear at about the 4,500rpm mark the clutch just starts slipping and the car races to 8,000 rpm. Also when I am shifting fast the clutch does not want to grab until you let off the gas and slow down.

Your flywheel could be loose.

 

as shitty as it is, you're prolly gonna have to rip it all apart again for further inspection.
