Need help with non vtec to vtec swap

[prosuperstar5]

I have a 93 honda civic ex 5 speed I believe its the d16z6 and I'm about to purchase a jdm d15b to swap in. I'm only ordering the engine from one company, what else do I need to make it work? Thanks everyone

Your current engine is already VTEC...
