From 1992 to 2007, the Subaru EJ151 1.5-liter gasoline engine was manufactured in Japan and fitted to multiple iterations of the world-famous Impreza model. The motor, which functioned as the base power unit, stood out for its modest features.

There are 2 modifications:
- EJ151 with a compression ratio of 9.4 and a power of 97 hp.
- EJ152 with a compression ratio of 10.0 and a power of 102 hp.
The engine was mounted on:
- Subaru Impreza 1 (GC) in 1992 – 2001;
- Subaru Impreza 2 (GD) in 2000 – 2007.

Disadvantages of the EJ15 engine
Even the Impreza cannot be driven with this engine due to its low power;
The oil burner and ongoing oil leaks from gaskets and seals come in second;
Here, a significant decrease in lubrication frequently causes the liners to rotate;
This unit frequently overheats because of the ineffective and unreliable cooling system;
The block led after overheating, as indicated by the appearance of a knock in the fourth cylinder.
