I have been researching this issue for my 2000 Carrera 2 with 34K miles.
A local shop quoted me $2400 to just replace the IMS with the LNE upgrade.
It seems that it costs about the same to do a clutch replacement along with the LNE upgrade. See my thread "Where to get the L&N IMS replaced?" below.
An independent shop near me quoted an extra grand to do the clutch, but one poster said the same shop charged him around $2400 to do clutch, AOS and LNE?
Go figure!
