|None of the 1996 models had Nissan Valve Timing Control System.
The reason for this is that OBD2 required that they have a feedback system to check the cam phasing change. Nissan figured it wasn't worth the R&D effort for the final model year of the vehicle in North America. Japan models kept with OBD 1.
The big key is that without NVCS, low and midrange power/torque would be less, if all things are equal. The peak number might have been affected because Nissan tried to compensate by changing cam profile to give more low/mid range power/torque with the trade off being peak power.
