well its a 96 and it does have a vtec already installed in it. i installed a new short ram air intake but i knew that wouldnt help me out too much unless i also have other parts? but what do i need exactly? i have also installed a new gas regulator in it. i figured swapping out the engine itself to a b18 or b20 might help but if i don't have the money to do that then what can i do to my engine as it is now?
