We are starting a new project car.  This is a 2003 911 C2 Carerra.  We are going to be doing periodic episodes where we are going to transform this 911 into a non badged monster.  Keep coming back to see what mods we do and how much hp we can add to a C2.

Our first mod is to install a K&N Cold Air filter.  Our dynos showed an 18 whp gain.  A huge difference in mid-range rpm gains and a new explosive sound makes this mod probably the best hp to cost ratio you can buy
