2008-2012 Subaru EJ257 STI 2.5 Liter Shortblock
This is a genuine Subaru EJ257 2.5 liter fully loaded and pre-balanced shortblock. Though this shortblock is standard equipment on the 2004-2012 US Market STI and features a slightly different piston dome, it will bolt up directly to any 2008-2012 WRX and is compatible with all 2008-2012 WRX accessories and engine components. This is a great option for WRX owners that may want to build a spare motor or who need to replace a damaged motor. The full rotating assembly comes balanced, sealed and loaded with an OEM crank, rods and pistons-- just bolt it up! These 2.5L short blocks do vary slightly depending on build date so please check your date before ordering. The build date of your WRX can be found on the information plate located in the driver's side door jamb.
- THIS IS NOT A COMPLETE MOTOR: This is a fully assembled bottom end, which consists of a block, crank, rods and pistons only. You will need to reuse your stock cylinder heads or purchase replacements.
- For high-powered applications, we recommend replacing the cast OEM pistons in this block with CP Forged OEM-size units.
- For shipping outside of the continental US, give us a call.
