X51 Power package
I'm looking at a 2004, 40th anniversary 996 with the factory X51 package. Is this engine still prone to the IMS failure? Or does it have internal upgrades similar to the turbo motors.

It is susceptible to all the normal failures. Mine had the RMS replaced at a little over 9,000 miles last summer just before it went to its new owner.

Mine is at 47,000 miles and going strong, no leaks ever. The HP upgrades come from intake and heads, so engine internals/seals have same vulnerabilities as standard 3.6 engines.
If you decide to get it, you'll love the way it comes on the cam at 5,000 RPM!

Same potential failures, only you will be going alittle faster when they happen.
Porsche does offer a upgraded IMS that can be replaced to now, it is larger from what I understand with a slightly different bearing. It's not as nice as the aftermarket one but it is Porsche. I believe it is also what is in the 997.2 now, although don't quote me on that as I havn't gone back and double checked the parts catelog.

Too early for me to say, the motor has 2k miles on it with one DE event.
The 997 has 8.5k miles with a multitude of DE events, and so far knock on wood everything is okay.

If the engine is one that is destined to fail, would it happen early (<20K miles) or could it happen anytime? Are higher mileage cars (assuming good records) better & less likely to fail.

There are always exceptions to anything, and because there are so many types of failures, othing is absolute. But in general, from just reading the forums on this topic to death, once the car is past 60k miles or so, if there isn't an RMS or IMS issue, the chances appear to drop significantly. Of course, there are still cracked heads, AOS, coolant tanks, etc, etc, but they are not as incredibly expensive as an IMS failure. FWIW, RMS is not really a big deal at all. 997.2 has no IMS. Hopefully, mine will last until 2015, when I should be able to justify a used 2010....
