The Best Toyota Engines
UZ-FE Series
1UZ-FE, 2UZ-FE, 3UZ-FE
These V8 engines are legendary for their durability and smooth power delivery. They are found in vehicles like the Lexus LS400 and Toyota Land Cruiser, known for longevity and reliability.
3MZ-FE
A 3.3L V6 engine used in models like the Toyota Highlander and Camry, recognized for its balance of power and efficiency.
2JZ-GE / 2JZ-GTE
These inline-six engines, found in the Toyota Supra and Lexus GS, are famous for their indestructibility and performance potential, particularly the twin-turbocharged 2JZ-GTE.
1NZ-FE
A compact 1.5L engine praised for reliability, often found in the Toyota Yaris.
5VZ-FE
A robust 3.4L V6 used in trucks and SUVs like the Toyota Tacoma and 4Runner, known for durability and off-road reliability.
1GR-FE (Updated Version)
A 4.0L V6 engine powering models like the Toyota FJ Cruiser, offering excellent torque and reliability in later versions.
Honorable Mentions
2GR-FE: A versatile 3.5L V6 found in a wide range of Toyota and Lexus models.
5S-FE: A reliable 2.2L inline-four engine from the Camry and Celica.
22R-E: An iconic 2.4L inline-four, especially popular among off-road enthusiasts.
1UR-FE and 3UR-FE: High-performing V8 engines for luxury and utility vehicles.
A25A-FKS and M20A-FKS: Modern, efficient engines with excellent balance between performance and fuel economy.
The Worst Toyota Engines
4GR-FSE
This 2.5L V6 engine suffered from carbon build-up due to direct injection, leading to performance and reliability issues.
2AZ-FE
A 2.4L inline-four plagued by excessive oil consumption, often leading to engine failure.
3VZ-FE and 3VZ-E
Early 3.0L V6 engines that suffered from head gasket failures and cooling system issues.
7M-GE and 7M-GTE
These inline-six engines from the Toyota Supra were notorious for head gasket problems due to insufficient torque specifications during assembly.
Engines with Mixed Reputation
1AR-FE and 2AR-FE
These engines, though generally reliable, have shown a decline in reputation due to oil consumption issues.
1MZ-FE
While initially promising, early models had problems with oil sludge due to inadequate maintenance intervals.
1ZZ-FE
This 1.8L engine was efficient but suffered from early wear on piston rings, causing oil consumption issues.
1GR-FE (Original Version)
The early iteration of this 4.0L V6 had some durability concerns, later corrected in updated models.
Hall of Fame Toyota Engines
