2.8L L28E I4: A SOHC, 12-valve inline-six featuring a cast-iron block and an aluminum alloy head (typically the "N42" or "N47" castings).
Fuel Injection: The Bosch L-Jetronic system was the first mass-produced electronic fuel injection for the Z-car, utilizing an Air Flow Meter (AFM) with a mechanical flap to measure intake volume.
Output: Produced 170 hp @ 5,600 rpm and 163 lb-ft @ 4,400 rpm, providing a significant torque advantage over the earlier 240Z and 260Z models.
Cooling: Features a high-capacity radiator and, on models equipped with factory A/C, a more robust five-blade cooling fan to manage the thermal loads of the L28 block.

Transmission: Available with a 4-speed manual or a 3-speed automatic; in 1977, a 5-speed manual (the FS5W71B) was introduced, significantly improving highway fuel economy and reducing engine drone.
Differential: Utilized the R180 or the beefier R200 rear differential (on later models/5-speeds), mounted in a subframe to isolate gear noise from the cabin.
Clutch: A 225mm hydraulic single-plate clutch, designed to handle the increased torque of the 2.8L engine compared to the 2.4L predecessor.

Suspension: Four-wheel independent suspension using MacPherson struts in the front and Chapman struts in the rear, providing the communicative handling that defined the S30 chassis.
Safety Impact: Characterized by the large, energy-absorbing 5 mph bumpers, which added roughly 8 inches to the car's overall length and increased the curb weight by nearly 300 lbs compared to the 240Z.
Braking: Standard power-assisted front disc brakes and rear drums, featuring a larger master cylinder and vacuum booster than earlier models to compensate for the added vehicle mass.
