    M45 Automotive Subaru EJ25 Complete  Short Block

    At the core of our engine-building program, we are fully dedicated to doing our best and protecting our reputation. We use only the highest-quality components and specialized machining and assembly techniques, ensuring they perform well and last long. Our goal is to create top-notch engines that exceed expectations and last for a long time.

    The engine case, composed of new Subaru OEM case halves, has been subjected to a thorough Bore and Deck process. This includes precision boring and honing of the case halves, ensuring perfect fitment and alignment. A torque plate is utilized during the honing process to enhance the precision further, resulting in a flawless engine case that guarantees optimal performance. Central to the design of this short block is a OEM Subaru Nitrided Crank.

    The engine boasts a premium Wiseco Subaru EJ257 WRX/STI 99.75 forged piston kit. Forged pistons, known for their exceptional strength and wear resistance, add significant value to the engine's performance and overall durability. If it's modified for more power, the stock pistons may not be able to withstand the increased stress. This is where forged pistons come in. We have also equipped the engine with high-grade piston rings and seals, improving the engine's compression and oil control. This not only amplifies the engine's efficiency but also bolsters its long-term durability.

    The Stage 2 Engine also incorporates new forged connecting rods. Complementing these are hardened rod bearings and main bearings, crucial components that endure high-stress conditions and minimize wear, thereby extending the engine's lifespan.

    In addition, this package comes with wrist pin and cover seals at no extra cost. These crucial components play a vital role in the engine's operation.
