The 2002 Nissan Frontier offered two engine choices: a small four-cylinder for efficiency and a larger V6 for extra power, with transmissions and trims varying accordingly.
Engine Options
Before listing the engines, this section explains the two powertrains available in the 2002 Frontier, which influenced performance and capability.
- 2.4-liter inline-4 KA24DE
- 3.3-liter V6 VG33E
In short, buyers could pick between the KA24DE for efficiency or the VG33E for stronger performance and towing potential.
Performance and Specifications by Engine
KA24DE 2.4-liter inline-4
The 2.4L KA24DE is a compact four-cylinder engine designed for economy and reliability. It typically produced around 140–150 horsepower and roughly 150–165 lb-ft of torque. It was commonly paired with a 5-speed manual or a 4-speed automatic transmission, and it was favored on base and two-wheel-drive models for better fuel efficiency.
VG33E 3.3-liter V6
The 3.3L V6 VG33E offered more power and torque, typically delivering about 170–180 horsepower and around 200–210 lb-ft of torque. It was chosen for those who needed stronger acceleration, towing, or off-road capability, and it could be paired with automatic or manual transmissions depending on the trim.
How to Identify Which Engine Your Truck Has
If you own or are shopping for a 2002 Frontier, you can verify the engine type by checking the engine code on the engine itself or on the emissions label under the hood, which lists KA24DE for the four-cylinder or VG33E for the V6. The VIN can also be used to pull a build sheet that confirms the original engine and drivetrain.
Summary
The 2002 Nissan Frontier offered two core engine options: a 2.4-liter inline-4 KA24DE for efficiency and a 3.3-liter V6 VG33E for more power and capability. The choice affected performance, towing, and drive feel, reflecting the range of uses the Frontier targeted in that model year.
