You need to tailor your engine build around the use of nitrous. I agree with others that have stated the top ring is too high and is going to be exposed to the shock and higher temps related to nitrous useage. Also, nitrous doesn't like moly coated rings either, it will flake off in a hurry and trash your cylinders. Stainless is a much better choice, but more pricey. Cam choice is also critical when using nitrous, when using the higher HP shots, its not good to use the same cam as you would for a N/A setup, a wider LSA should also be used.
