Buying a Mitsubishi Evo X - are there any known issues?

I am about to take the plunge on a Mitsubishi Evo X - FQ 360. Is there any mechanical issues I should be aware of?
These are more powerful than some race engine and consequently their life can be very short and 5000 mile servicing was essential. See more in the entry in car by car here:
