Writeup:

This Z31 is my first new car, and I have owned it since 90.  I started modifying it in 2000.  I never anticipated going this far with the car, but it has become a love of mine, and an expression of myself.  I have just installed new cams and have yet to dyno the power the engine makes with them.
