Review SUBARU 2.5 Engine Longblock 117k fits WRX STI 2008–2010

The Subaru 10100BR880 is a longblock 2.5-liter engine specifically designed for the Subaru WRX STI models produced between 2008 and 2010. This high-performance engine is a crucial component for those seeking to enhance the power and durability of their vehicles.

The Subaru EJ257 engine, as it is also known, is a horizontally opposed, or "boxer," design with a flat configuration. This unique layout offers several advantages, including a lower center of gravity, improved balance, and a more compact design compared to traditional V-type engines. The engine block is made of aluminum alloy, which not only reduces weight but also helps the engine to dissipate heat more efficiently.

The longblock design of the Subaru 10100BR880 includes the cylinder block, crankshaft, pistons, connecting rods, and cylinder head with camshaft and valvetrain. Each component is meticulously crafted to deliver maximum power and reliability, making this engine an excellent choice for high-performance applications.

The engine features a twin-scroll turbocharger system, which improves turbocharger efficiency by minimizing the lag time between throttle input and power delivery. The engine also includes Subaru's Dual Active Valve Control System (DAVIS), which optimizes intake and exhaust valve timing for improved power and fuel efficiency.

The Subaru 10100BR880 engine has a displacement of 2,497cc (2.5 liters), and it produces a peak horsepower of approximately 305 hp at 6,000 rpm and a peak torque of around 290 lb-ft at 4,800 rpm. These impressive power figures make this engine a favorite among Subaru enthusiasts and performance tuners.

This Subaru engine longblock has been refurbished and rebuilt to meet or exceed OEM specifications, ensuring that it delivers the same level of performance and reliability as a new engine from the factory. Each longblock undergoes a rigorous inspection and testing process to ensure that it meets the highest quality standards.

Installing the Subaru 10100BR880 engine longblock into your Subaru WRX STI (2008-2010) will require the use of compatible engine components, including the transmission, intake and exhaust systems, cooling system, and electrical components. It's essential to ensure that all components are compatible and in good working condition before installation to avoid any potential issues.

In summary, the Subaru 10100BR880 longblock engine is a high-performance, rebuilt engine specifically designed for the Subaru WRX STI models produced between 2008 and 2010. With its horizontally opposed configuration, twin-scroll turbocharger system, and impressive power figures, this engine is an excellent choice for those seeking to enhance the performance and durability of their Subaru.

3. Availability: Aftermarket support for the WRX STI engine is strong, making it relatively easy to find parts if needed.

Ultimately, the decision to buy this engine depends on your personal circumstances, budget, and willingness to take on the potential risks.

Recommendation:

If you are set on purchasing a used longblock engine for your Subaru, it is highly recommended to do thorough research on the specific engine and seller.
