The '96-99 Pathfinder had the VG33E (168 hp and 196 lb·ft torque).
I believe the above is correct at least.
WOW! Not even close.
1984-1989 model 300ZXs were Z31s. They were equipped with either VG30E or VG30ET in North America.
1990-1996 model 300ZXs were Z32s. They were equipped with either VG30DE or VG30DETT motors.
Almost no parts from the two motors will interchange.
VG30E motors were used in many Nissan models over the years (300ZX/Maxima/Truck/Pathfinder/etc). The VG33E and VG33ER (supercharged version) were only used in the trucks (Trucks/Pathfinders/Xterras/Quest).
VG = V6 engine30/33 = 3.0/3.3 L displacementD = DOHCE = EFIR = superchargerT = single turboTT = twin turbo
And yes. Z31 = chassis designation, not engine designation.
