New to the United States in 2003 was the Subaru WRX STi. It comes stock with a 2.5 Liter semi-closed deck motor, and strong cast internals. The block will drop right in a WRX as it sits, but we offer this motor with some upgrades for your piece of mind.

The Stage 2 Axis Power Racing Motor consists of a very strong block with forged pistons. It has 25% increase in displacement over your WRX shortblock and can withstand far more abuse. This would be a perfect upgrade for someone looking to make serious power without the serious price tag.

Stage 2 Components:
- 2.5 L STi Semi-Closed Deck Shortblock
- Stock Sleeve Liners
- Stock USDM 2.5 L STi Crankshaft
- Stock USDM 2.5 L STi Connecting Rods
- CP Forged Pistons
- 8000 Rev Limit Recommended
