EJ205 LongBlock Perfected

The EJ205 is a legend in Subaru’s performance history, kickstarting the turbocharged WRX craze in the early 2000s. It paved the way for the bigger, badder EJ engines that followed, but it’s still loved by gearheads for its tuning potential and reliability. This boxer engine helped cement Subaru's rep as a turbo powerhouse, and it’s still a favorite for those looking to boost their ride without losing that iconic WRX spirit!

Say Goodbye to Factory Flaws

• Rod Bearing Failures: Often in modified or high-mileage engines; proper maintenance can help prevent this.
• Oil Consumption: Some engines may consume oil, requiring regular monitoring.

Precision Executed

The engine case, using seasoned 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.

Unmatched Durability

At the heart of this short block is a new OEM Subaru Nitride-Treated Crankshaft, designed for peak performance and durability. Specifically designed for 2002-2005 WRX.

The Power of Resized Connecting Rods

Resized connecting rods restore original dimensions, ensuring a precise fit and optimal oil clearance, reducing rod knock risk, and enhancing engine durability. Complementing these are ACL or King hardened rod bearings and main bearings, crucial components that endure high-stress conditions and minimize wear, thereby extending the engine's lifespan.

Premium Wiseco Subaru EJ205 WRX 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 cast 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.

Remanufactured Heads

The cylinder heads have been precision resurfaced, with lash clearance adjusted, and a complete valve job executed. Qualcast Steel Valve Guide Sets and new valve stems have been installed to enhance durability. The heads are assembled using Six Star Seal Gaskets, and all fasteners are torqued to factory specifications.

Made Stout with ARP

ARP studs offer precision alignment and are thread-rolled after heat treatment, boosting fatigue strength by 1000%. Despite the higher cost, this process ensures superior durability. Each kit includes premium washers. Essential for performance engines under increased boost, ARP head studs are the top choice for your WRX, providing an option to enhance your engine’s strength.
