For eight years we were snowbirds and the Z sat in our AZ house during the summers. About 10 years ago we came back in the fall only to find the turbo seals were leaking. I replaced the turbo's with JWT Sport 500's and had JWT reprogram the ECU for stock injectors. I didn't wish to upgrade the injectors as more power puts more strain on the drive train. I did pick up 50HP in the process. One advantage to this car would be the ability to change out the injectors and reprogram the ECU for more power relatively inexpensively. However, since I planned on keeping the car forever, I didn't want to stress the drive train components.
