To give you a rough idea, here's what my K24a DC2 is like:



This car is my daily, and to be honest, its fine. Im running a 3" exhaust setup, and yes it is loud when your stomping on it. But cruising along in 6th it's comfy as. Im using 62a Hasports and a K20 oil pump, and the vibrations really arnt that bad. Also, I dont have an IACV and my idle is fine, not rough at all.

With a full interior, its a great daily drive, Start stripping interior, plastics, carpet, rear seats etc, and it's a different story.
