You have VTEC engine, not a vtech engine. vtech makes phones. It's a header, not headers, you have an inline 4. Don't buy anything that says it's JDM, it's not. An H22A is the best engine to swap but you're going to spending a lot of money just to get more potential. I wouldn't do anything other than basic bolt ons if you have an automatic, they die easily. That's all I can think of right now.
