This is a genuine Subaru EJ207 2.0 litre shortblock. This shortblock is standard equipment on the V7-V8 UK STi. The 2.0 litre block makes a great upgrade for all WRX models. The STi block features a semi-closed deck for increased strength. This motor is physically a bolt-in for all WRX and STi models (WRXs will require ECU tuning, bigger injectors, etc.).

NOTE:

1. 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.
2. For high-powered applications, we recommend replacing the cast OEM pistons in this block with Mahle Forged OEM-size units.
