The cylinder bores are finished to a mirror-like surface, which permits a perfect seal with the piston rings, ensuring optimal engine performance and efficiency.

The IAG Subaru WRX EJ20 2.0L IAG-ENG-1455 Performance Tuff Closed Deck Block is designed to accommodate high-performance aftermarket components, such as forged pistons, high-compression rings, and high-performance cylinder heads. This block is an excellent foundation for building a high-horsepower engine, capable of withstanding the increased power and stresses placed upon it.

Additionally, this closed deck block is supplied with new main and rod bearings, making it a complete engine block upgrade. The installation process is straightforward, and IAG provides detailed instructions and technical support to ensure a trouble-free installation. This block is a direct replacement for the stock block, making it an excellent choice for Subaru WRX enthusiasts seeking improved power, reliability, and durability.

In summary, the IAG Subaru WRX EJ20 2.0L IAG-ENG-1455 Performance Tuff Closed Deck Block is a high-quality, high-performance engine block designed for Subaru WRX models from 2002 to 2005. It offers superior strength, durability, and thermal stability compared to the stock block, making it an essential upgrade for those seeking maximum power and reliability from their EJ20 engine.

Buying a (2002-2005) Subaru WRX with an IAG (Industries Aftermarket Group) closed deck EJ20 2.0L engine can be an intriguing option for those looking for improved performance in their Subaru. This engine upgrade is popular among Subaru enthusiasts due to its increased power and durability. Below are some pros and cons for your consideration:

1. Enhanced Power: The IAG closed deck block is known for its ability to produce more power than the standard Subaru engine. This makes the car more responsive and fun to drive.

2. Increased Durability: The closed deck design helps to reduce engine oil consumption, as well as preventing oil from entering the coolant system. This results in a more reliable and durable engine.

3. Improved Performance: The closed deck block allows for the use of higher compression pistons, which results in better combustion and an increase in horsepower and torque.

4. Enhanced Cooling: The IAG engine features an improved cooling system, which helps to prevent overheating and ensures optimal engine performance.

1. Cost: The IAG engine upgrade is a significant investment, with the block alone costing several hundred dollars. Additionally, the installation process can be complex and time-consuming, adding to the overall cost.

2. Complexity: The installation process for an IAG engine upgrade can be complex, requiring specialized knowledge and tools. This may make it difficult for some DIY enthusiasts to install the engine themselves.

3. Potential Compatibility Issues: It is essential to ensure that all components of the engine are compatible with one another. In some cases, the use of aftermarket parts may result in compatibility issues, which could lead to engine damage or poor performance.

4. Potential for Increased Noise: The IAG engine upgrade can result in increased engine noise, which may be a concern for some drivers.

In conclusion, the IAG closed deck EJ20 2.0L engine upgrade for a (2002-2005) Subaru WRX offers several advantages, including enhanced power, increased durability, improved performance, and enhanced cooling. However, the significant investment required, as well as the complexity of the installation process, are potential drawbacks.
