Iv'e been looking into crower cams the past few weeks as a method to extract more power from my D16y8. My problem is that ther cams come in 4 forms.

Stock replacement: slighly better than stock
Stage 1 : More agressive
Stage 2 : street/strip
Stage 3 : race only :P

My question is what is the most agressive camshaft i could put on without sacrificing drivablity while extracting most power. eg I don't want to be driving around down when my car involintarily self implodes on itself causing a black hole to form.
