1.its better that what you have now for starters.2 it has 130hp stock.3. yes there that cheap and there extremely disposable.if you blow it so what get another one.
its a bit harder to say that with a b16.because they cost a lot more than the zc.either way its better than what you have.if you try to run nos with that manymiles your motor isnt going to live past your first run.most zc motors have 30 k on them .good luck
