You have the cam and aren't sure how the motor will be done ?
I'd think that the cam choice should steer you in a specific direction here.
A cam that is optimized for N/A would not be my first choice for either boost or spray and vice versa.
The final answer still begs another question.........if you keep your wallet in your right hip pocket and don't list to the left when you sit down , I'm thinking N/A might be a nice choice.
Or a conservative spray set up.
To my way of thinking , it takes deep pockets to get a force fed motor running and deep pockets to keep a well done nitrous motor running.
Deeper than N/A anyway.
