Engine oil was changed a week before the incident. I used only Mobile One synthetic oil. Less than 20 miles driven since that oil change.
Perhaps a previous owner was not as prudent with oil changes?

Next is why again.
Most engine builders will check for clues by locating color patterns left on the crank journals, bearing caps and markings on the cylinder walls.
From what I can see, my guess is an oiling issue which would lead me to check the quality of the oil that was in the car and oil system.
I've owned the car for 3 years and the routine oil changes were done very frequent. Assume that the previous owner did not change the oil as often, can it contribute to issue with my engine?
If you are referring to the bottles you get off of the shelves, not unless you bought like 100 bottles of the stuff. The thing is, octane booster is only the octane for that bottle. So 500 ml of 104 octane isn't going to budge 8 gallons of 91 octane. I haven't done the math yet, but it would be like a .1 boost in overall octane once you mix it altogether. You're better off getting 100 octane race fuel and topping off the tank.
Questions:
What do you guys think it happened?
What else can I do to prevent detonation?
Have I not done enough to ensure proper preparation for CTSC?
Does any one know any low mileage (40,000 – 50,000 mi) motor for sale?
Please comment and if you would like to call me, I can be reached at (206) 228-5988.
Thanks in advance.

The engine bearings (or any other part of this engine) show no signs of abnormal wear or poor lubrication.
As disconcerting as it my be to accept, the reality is that this crankshaft failed. it is unusual to be sure but there are no signs that this was anything but a part failure.

John inspected my car and found #5 and #6 cylinder piston disintegrated and the engine has a small crack (I noticed a pool of oil while the car stalled on the freeway). I am going to need a new motor. To make matter worse, we found that bits and pieces of the shattered pistons made their way through the intake and now my supercharger is also damaged.

I built a new T-sleeved engine for a friend of mine, and he had me rebuild his original engine as a back up and he has never used it. If you have any interest e-mail me and I will give you his contact info.
Is it fair to conclude that the NSX is best kept NA on a stock motor?
If you want HP and cheap HP get a MKIV?
but I purchased a C5 Corvette to turn into a Supercar because of the tire size (Known as one of the best track cars). My first event the brake pedal went to the floor and stayed there. I improved that area and my second event I realized that I could over heat the engine 260f water 308f Oil. Even the Miata will overheat with the OE radiator. The point is that I have never seen a better OE track car then the NSX, and tracking is more abusive then anything most will do to a car.
