Hey guys I'm new to the forum and honda 4cyl. I have a 95 civic ex with the stock d16z6. I need more power using factory parts and it has to be NA for the rules. I'm limited to using factory honda parts for the class but it can be tuned. I was wondering what factory honda parts to look for that will bolt onto the d16z6 and make more power. Any help or info would be greatly appreciated. But it has to be NA for the rules.
