On this page, you are looking at the Subaru OEM 2.5L EJ257B STI Short Block. This is a fully assembled short block that includes all of the main guts such as the factory pistons and rods, as well as the crankshaft and main seals to make it ready for the installation. You or your preferred mechanic would have to bolt on the heads, oil pan, and fill it with the proper fluids to make your vehicle roadworthy again.

Warranty Disclaimer: Subaru of America will only warranty parts installed by a CERTIFIED Subaru Dealership. The part being installed must also match the vehicle VIN. IE If you install an STi block in a WRX at your friends shop, do not expect a warranty claim to come through if it explodes! Please use your best judgement.
