Overview of ej255

ej255 and ej257 may look similar, but they are two very different engine designs. ej255 is a 5 liter turbocharged engine that features a closed deck design, which allows for greater strength and durability, as well as improved cooling efficiency.

5 liter turbocharged engine that features a closed deck design, which allows for greater strength and durability, as well as improved cooling efficiency. The ej257, on the other hand, is a 7 liter turbocharged engine that features an open deck design, which offers greater power and torque, but with a shorter lifespan.

To put it simply, the ej255 offers superior strength and longer life, while the ej257 offers more power and torque, but at the cost of longevity.

5:1 compared to the EJ255’s 5:1, which makes it more efficient and able to produce more power.

Additionally, the EJ257 has a cast iron block, rather than the aluminum block of the EJ255, which makes it more durable and capable of withstanding more stress. The EJ257 is a great choice for those looking for a reliable and powerful engine.

Difference in power output

Difference in power output

The difference between the Subaru EJ255 and EJ257 engines lies in their power output. The Subaru EJ255 engine produces up to 224 horsepower, while the EJ257 engine produces up to 300 horsepower. This significant difference in power output can be attributed to the larger displacement of the EJ257 engine.

This significant difference in power output can be attributed to the larger displacement of the EJ257 engine. The EJ257 has a 5 liter displacement compared to the

5 liter displacement of the EJ255, which allows it to produce more power. The EJ257 also features improved intake and exhaust systems, a larger turbocharger, and a higher compression ratio, all of which contribute to its higher power output.

With an additional 76 horsepower, the Subaru EJ257 engine is the clear choice for drivers who want to maximize performance.

Difference in engine block size

When it comes to engine blocks, size matters—especially when comparing the EJ255 and EJ257 Subaru engines. The EJ255 is a 5-liter turbocharged engine, while the EJ257 is a larger

5-liter turbocharged engine. The difference in size between the two comes down to the cylinder bore.

0 mm, while the EJ257 has a bore of 95 mm and a stroke of 90. 2 mm.

This difference in stroke length results in a larger displacement for the EJ257, allowing it to generate more power. Ultimately, the EJ257 offers greater potential for performance tuning and higher power outputs than the EJ25

Difference in price

Difference in price

When it comes to Subaru engines, the difference between an EJ255 and an EJ257 can be defined by the amount of power and torque each engine produces. The EJ255 engine is a 5-liter, turbocharged version of the EJ25 engine, which produces 224 horsepower and 226 lb-ft of torque.

On the other hand, the EJ257 engine features a larger displacement and produces more power, with 300 horsepower and 300 lb-ft of torque. That difference in power and torque means the EJ257 engine is better suited for performance applications, while the EJ255 engine is more suitable for everyday driving.

In terms of price, the EJ257 engine can be more expensive than the EJ255, making it a more cost-effective choice for those who are looking for an engine with more power and torque.


Conclusion

In conclusion, the main difference between the EJ255 and EJ257 engines is the size. The EJ255 is a smaller engine with a displacement of

5L while the EJ257 is a larger engine with a displacement of 7L. Additionally, the EJ257 has a higher power output than the EJ255, making it the preferred choice for performance applications.

Both engines offer excellent reliability and performance, making them a great choice for many applications.
