Last October, I purchased a 2013 4dr LX. At first, all I wanted was cosmetic work, considering all I was looking for was an economical car after I sold my 2012 mazdaspeed3 and became a proud poppa. But after riding in my cousin's SI's, I found myself missing that extra bit of power. I'm not looking to add incredible horsepower, but I just want the feel of a little added power. It's a single cam and I've heard turbos do the trick. I've also heard intakes, exhaust, and headers would be all I need. What would you guys recommend? Links and sources would be helpful. Thanks in advance!
