yep no problem at all, just make sure you match the clutch kit to the gearbox, not the engine and re-use your old flywheel.
If your car has a 200mm clutch though, I'd advise you upgrtade to a MK2 GTI 210mm clutch kit and flywheel. You may be able to use the MK3 flywheel thoguh, I'm not 100% sure its the same as a MK1/2 one though...
