This is not your average WRX. Professionally rebuilt and tuned by Possum Bourne Motorsport, this EJ205 has undergone a full FLH565-spec build with no shortcuts. Backed by thousands in high-end parts, precision machine work, and dyno-proven tuning, this Subie is a rare opportunity to own a fully sorted, forged, and track-capable Subaru that's just as happy ripping backroads as it is carving through apexes.

Currently detuned to just over 300hp, this car could easily handle over 500hp
