3) CAR magazine claims that they are going through clutches at a very high rate in their uk spec EVO VII. What is the reliability of mitsu clutches?
4) Anyone know of a good Mitsu service department with good techs in the DC/NoVA/MD area? I've been buying BMWs simply because I've had very bad experience with the service departments of more common cars (honda, subaru, vw, and even audi).
5) I know the turbo is oil cooled according to mothership, but I am
assuming there is also a water jacket? I base this on the fact that I haven't seen a pure oil cooled turbo in years. The reason the subaru WRX does not need a cooldown period is due to the design of the coolant system plumbing, which keeps a reservoir of coolant above the turbo and as the hot turbo boils away the coolant, more coolant drips down.
6) What is the service interval on the engine
7) Is the engine closed deck or open?
8) How reliable is the rear mechanical diff? Is it a clutch pack type
diff which in other applications is known to start failing around 25k-35k miles

dealer in Tysons Corner has very good service he had a Montero Sport but I don't know if he had any significant problems with it.btw I know it's off topic but do you know who it was that knew of a dealership in NoVa that is supposed to be selling the Evo at below MSRP?

The 4G63 in the EVO is a open deck?
HORSECRAP.
The 4G63 has always been a closed deck. There are guys making 700+ hp on the DSM 4G63 engine.
As long as the engine in the Evo is as strong or stronger than the one in the DSMs, then it can handle whatever you throw at it.

Well, this is not rocket science. Can someone find out for SURE if the engine is closed deck or open?
Other thoughts: What is the survivability of the wing? I assume this wing will be a hot theft item as people steal the wing and put it on their lancer OZs etc (see also the HIDs from the acura CL/TLs being stolen)
One good thing is that this car comes with an immobilizer.

Here is a picture of a couple 4G63 blocks SAWED IN HALF!
It actually doesn't matter if it's closed or open, as people have already proved it can handle 700hp stock, so the question is pointless! Pointless I say!
That picture is from Magnus.
