If someone were not to steadily beat on the motor, using it as a DD and only pushing it occasionally, would the stock RA with stock C/R be expected to hold boosted power ~ 8-9 PSI max (I.E. reaching 550-580 WHP on 93) for about the same life of the stock motor?
Fueling would also be upgraded to LT4 parts.
Average ambient temperatures and humidity levels similar to Florida.

I did quite a bit of homework and was soo close to doing exactly what you want to do but I got bit by the NA bug instead. Seeing that you come from a turbo background the general rule of thumb is the same, every lb of boost is equal to the weeks of satisfaction before you want more (7lbs=7 weeks and then your looking to pulley down). I loved the ADM kit that was available but knowing me, I would want more eventually so I probably would have went the Maggie route...more cfm and larger cooling bricks too.
Good luck with whatever you choose and please keep us posted. If you do go the 1.7 route and get itchy for more, you could probably get a flex sensor and go e50 or so and get the benefits of ethanol.
