Before asking your question please search, if you don't find anything in the search then you can ask your question. Please be as specific as you can with your question. What year and model do you have? What is your primary use of the car? Are you planning on going Forced Induction? The more info you give us the better we can answer you questions. Also, any use of VTEC spelled VTECH or any other butchers of it may result in your post being deleted.
