My car is a 2004 honda civic Si 1.7L (vtec) sedan. Any ideas how to upgrade performance?
The cheapest way to go is cold air intake and new mufflers, want to spend money? Turbo set up is the way to go. As I tell every younger gent is the upgrade worth more then the car is. Ive bult many cars over the years and lost so much money doing so. I would save my pennies and purchase a newer car, here is a good article on upgrading......http://www.procivic.com/pages- honda_civic_tuning/index.html
