Very small cam for now.
The car is a weekend fun car street racing and 200 hp shot is the plan

ok, well thats a different story.

is your engine together?

if it is together, how do you like the way it runs now?

if you tune it properly for the nitrous, you are ok with that compression and that much quench/squish although i would still run less quench squish.

you can also buy a deto sensor called a safeguard that controls the timing and retards it if it senses deto.

you "should" not quite be in the area where you need water or water meth injection.
