2006 Subaru STi

Asking $28,500
2006 Subaru STi

Overview

This Hawkeye STi offers 572hp at the wheels on E50 fuel thanks to an IAG stage 4 Tuff closed-deck block and a bigger rotated turbo. More aggressive GSC stage 2 cams drive an upgraded valvetrain, and a standalone Link ECU makes everything work well together. This example benefits from a long list of top-shelf upgrades and it has seen some significant maintenance to help keep it running strong.
