2004 Subaru Forester XT Conversion – IAG Short Block

[nggallery id=526]
Nearing 200k miles of enjoyment, Austin's extremely clean 2004 Subaru Forester XT clone was ready for a refresh. Previously swapped with a EJ255, it was time for round 3, with a simple goal in mind: aim for 300+awhp and build it for longevity and reliability. With a plan set in place, Andrew got to work creating the ultimate daily-driven combo, a 2004 EJ257-swapped Forester littered with STI bits, a setup prized by the lot of Subaru enthusiasts.
