CarBuzz recently covered Dirtfish rally school instructor Sam Albert's mission to fit a Ferrari V8 into his Subaru WRX STI. Now he's released a video of the ballistic rally car in action. Turn your speakers up for maximum aural pleasure because the X-pipe side exit exhaust setup sounds magnificent.

The video is a full shakedown following a tune on the dyno. The car flies around the Dirtfish complex with cameras and microphones to catch it from almost every angle. We're particularly fond of the full-frontal view provided by the roof-mounted camera. Seeing the 4.3-liter F136 Ferrari-Maserati engine sticking out of the hood is sublime. The Ferrari version of this engine was available in three different configurations, powering the F430 and F430 Scuderia, the 458 Italia, and the glorious 458 Speciale.

This particular unit is the 262 cubic-inch unit used in the Ferrari California.

Even with the bigger engine, Albert managed to keep the Subaru WRX STI's all-wheel-drive system intact. He also retained a 50:50 weight distribution, which is a magnificent feat of engineering.

He also says the new cooling system is holding up, and the car handles much the same as before the engine swap but with much-improved torque delivery and control. However, he's thinking of changing the final drive ratio from 3.9 to 5.44 but plans on running the car competitively before deciding.

He keeps the original Subaru Driver's Control Centre Differential (SDCC) locked most of the time but mentions it wasn't engaged on this short, tight track.

Albert built the car to compete in American Rally Association (ARA) sanctioned events but will need some restrictions to get there. The swap occurred because he realized a naturally aspirated engine had fewer restrictions. These vehicles are not limited to four cylinders, and the cut-off for displacement is set at 4.5 liters. Without restrictions, this particular Ferrari engine produces 483 horsepower and 372 pound-feet of torque.

He plans to give the engine-swapped WRX STI its competitive debut at the Olympus Rally in Washington this April.

This has to be the zaniest engine swap we've seen in a while, but the E30 BMW 3 Series equipped with the V10 engine from E60 BMW M5 gets quite close in terms of sheer ridiculousness.
