Toyota Corolla Engine

The modern Corolla has had two different engine families that it shared with the Celica. From 1993 to 1997, Corollas had two engine choices: a 1.6 liter 4A-FE and a 1.8 liter 7A-FE. The 1.8 was used in the GT-S. In 1998, Corollas was now powered by a new engine family. The 1ZZ-FE engines produced substantially more power and offered better fuel economy.

 

At 120 horsepower (at 5,200 rpm) and 122 lb-ft. of torque (at 4,400 rpm), the new engine produced more power than its predecessors and did not need to be revved as high to do it. Thus, the 1998 Toyota Corolla was considerably faster and more responsive at all engine speeds. The ZZ engine is an aluminum block engine that uses iron cylinder liners, now a very common design.

 

To distinguish its engines from other generations, Toyota uses a digit in its engine designations such as 4A-FE was the fourth generation A engine and the 1ZZ-FE, which is the first generation ZZ engine. In 2000, the next generation of the ZZ engine was introduced now utilizing variable valve technology or VVT-i that increased power by 5 hp and improved fuel economy by almost three gallons. 2003 also saw a major improvement with better fuel economy and added power.
