FEATURES & PRODUCT DETAILS
GrimmSpeed 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.
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.
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
