Pros and Cons of Buying a 2013-2014 Subaru 2.5L AT Engine Longblock (187,000 miles)

a. **Reliability:** Subaru engines are known for their durability and longevity. A longblock engine is essentially the entire powertrain from the crankshaft forward, so you're getting a substantial portion of the vehicle's powertrain that has already proven itself.

b. **Availability:** Aftermarket engine longblocks are easier to find and install than rebuilt or remanufactured engines, especially for popular models like the Subaru 2.5L.

c. **Cost-effective:** Longblock engines are generally less expensive than a full engine rebuild or replacement.

d. **Customizability:** If you plan on modifying your engine, a longblock engine can provide a solid foundation for building a high-performance engine.

a. **No Transmission:** A longblock engine does not include the transmission, which you'll need to source and install separately. This adds additional cost and time.

b. **Different Vehicle Components:** Depending on the condition of the engine and your specific vehicle, you may also need to replace various components such as the timing belt, water pump, or other engine accessories.

c. **Performance:** Depending on the condition of the engine and your expectations, the performance of the engine might not be the same as a freshly rebuilt or new engine.

d. **Installation Complexity:** Installing a longblock engine can be more complicated than a simple engine swap, especially if you're not an experienced mechanic.

A 2013-2014 Subaru 2.5L AT Engine Longblock with 187,000 miles can be a cost-effective and reliable option for those seeking to replace or upgrade their engine. However, it requires careful consideration of the associated costs and complexity, particularly the need to source and install a separate transmission.

If you're comfortable with the additional work and costs, and you're looking for a solid foundation for a high-performance build or a reliable replacement engine, a 2013-2014 Subaru 2.5L AT Engine Longblock could be a suitable choice. However, it's essential to thoroughly research the specific engine and its condition, as well as the availability and cost of the necessary transmission and other related components.
