Subaru OEM 2.5L EJ257B Short Block 2004-2021 STI

This brand new completely assembled short block is Directly from Subaru. This short block is ready to go. Just bolt on your heads and accessories, and it is ready to install in your car.

This is the OEM short block that came in the 2011+ STI. This has the induction hardened crank shaft and not the nitride crank shaft that was in earlier motors. This is a great place to start if you are building a hybrid engine with your 2.0 liter heads on a 2.5 liter block, or maybe you just need a replacement block for your STI. This comes with the block, crank, pistons, and rods completely assembled, and ready to bolt your heads on.

If you are putting this block in a car that it was not originally designed for, it carries no warranty expressed or implied.
