I am thinking at gettin a Zex 55 shot kit for my EX Civic, should be safe for a stock internal engine. What other things should I get, like colder plugs, beter wires, fuel pump? anything else?

Colder plugs. Copper NGKs or Zex plugs work nicely.

colder plugs and better wires will work good...get a fuel pressure regulator and bump the pressure up a few psi.
