Features & Product Details

RallySport Direct proudly carries a large menu of genuine Subaru OEM parts for those of you who need to get all of your performance and OEM shopping done in one spot, or if your local dealership has run out of stock on a particular part. 

On this page, you are looking at the Subaru OEM 2.5L Type RA EJ257 Short Block. This is a fully assembled short block that includes all 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. 

 

Here are the details:

  • Same casting as the latest EJ motors, "705"
  • Piston crowns are 2mm thicker
  • More support on piston wrist pins
  • Lower amount of cantilever produced
  • Slightly heavier pistons increase durability
  • Same strong Con Rods as 2018 STI
  • Overall, less prone to failure than previous STI blocks

    • Q: 2005 STI  JANKOCARS989715 months ago

      Installing this block on a 2005 STI. which oil pump is recommended? which head gaskets are recommended? ones that match the '05 heads but 2mm thicker? anything else needs modification?
    • Q: 2013 WRX  Ed9 months ago

      Are any modifications needed to fit this to a 2013 WRX?
      • 1 of 1 people found the following answer helpful

        A:  You would just want to verify the compression ratio with this block, and different headgaskets may be required. other than that it will physically bolt right up. Thanks!

    • Q: 06 STI  cruizinmax10 months ago

      Hi, will this fit stock 06 STI heads, thanks
      • 3 of 3 people found the following answer helpful

        A:  Yep! It will be a direct bolt on for your 06 STI heads, just make sure to get the headgaskets for your 06 STI and not the 08+ ones. Oh and go slightly thicker if you want to maintain the stock Compression Ratio :)
