ago. They charged me about $150 to install a new coil pack (part and labor). I dont know the cost of the part, so I wouldnt be able to tell you if it was a good deal or not. However, I've heard that their charges on labor and parts are closer to that of a Nissan dealership than to other shops that specialize in Z's. I could be wrong though. I've also got a buddy with an NA that had them drop a new engine in his Z. He's got about 70k on the engine, and has had no problems relating to the engine or install since the motor was put in.
