This 2012 Subaru WRX STI Limited in Obsidian Black Pearl is a no-expense-spared, sleeper build. It combines a forged EJ25 block, built heads, and a Haltech R3 ECU with a Precision 6466 rotated turbo and dual-pump flex-fuel system, all backed by a Tran-built transmission and ACT twin disc clutch.

The result: ~600 WHP daily, ~750 WHP tuned street, ~860 WHP max effort (~1,100 crank HP). Balanced with BC coilovers, Perrin bracing, and premium interior upgrades, this STI offers an unmatched blend of OEM refinement, hardcore engineering, and record-breaking power potential.

A true collector-grade, high-power Subaru — rare to find with this level of build quality and investment.
