The Subaru WRX STI is famous for its legendary boxer engine and impressive all-wheel-drive performance. But what happens when the traditional flat-four disappears and a Honda K24 takes its place? This unusual STI build combines a JDM K24 engine, a K20 oil pump and a Precision Turbo, creating a completely different character for one of Subaru’s most iconic performance cars.

Producing 370 wheel horsepower while retaining the original STI AWD system and six-speed transmission, this unique project delivers high-revving VTEC power, aggressive turbo sounds and explosive upshifts. Built in just five months by an enthusiast with a regular 9-to-5 job, this Subaru raises an interesting question: could a Honda-powered STI actually be more entertaining than the original?
