I second what barrym381 says. I have a 2001 Aum, and just before I had it remapped the gear box went, so I had it replaced as well as the clutch and fly wheel (oem parts). Touch wood, my clutch has been fine since the remap, which was done about 22 months ago. What you are most likely to need to replace after a remap will be the pcv pipework under the inlet, and the diverter valve.
