could a ls vtec with ctr internals handle a 55 shot of zex nitrous
yes it could, but the question you should be asking yourself is for how long can it handle it?
CTR pistons=very high c/r…not the best choice for any type of Forced induction, such as nitrous, or turbo.
Na and high c/r are fine
FI and low c/r are good.
You could pull it off with tuning, but without tuning i would not suggest it.
how about itr internals

calculate your c/r with what ever head and block you are going to use, then come back and as questions once you have a set c/r and ls/vtec set up.
This link gives you the codes for thi pistons click me
Nitrous LOVES compression. but high compression causes the user to use race gas or meth injection. Also you have to remember stock rods/pistons don’t enjoy more than 250-265whp.
compression isnt the problem, the factory cast pistons are the weak link. 75-100 max
