i just bought a 99 civic si. my first mod was a set of rays engineering gram lights in gold. other than that the car is completly stock. i wanted to know what a couple good parts were for the car this is what i was thinking just to start: aem v2 coldair intake apexi w/s exhaust jdm type r header. what are your opinions? let me know i also have a ls block that has blown rings and was thinking of a ls/vtec setup nothing too crazy but just to get this car to move faster.
