Island King: Turbo FR-S Hits 530hp On Dyno

The recipe is pretty simple. Subaru dudes have been strapping moderately sized turbos to their 2-liter boxers for ages, so seeing on on an FR-S/GT86 was bound to happen. In this case, they’re using the GTX3076 specifically along with a Haltech ecu. They built the motor too, otherwise I imagine a 530 horsepower 4U-GSE wouldn’t last very long.
