Ive been meaning to do mine in my GN. Granted it still pulls good, but with 100,000 on the motor; I'd rather spend $200 to get the job done the a few thousand for a new motor. I did them on my old WH-1 when it had 135K on it and I gained 2/10ths just from those alone. No other mods. Really woke the car up.
I need to do the springs and a few other small things before I hit the track again.
