The Toyota 86 chassis is no stranger to engine swaps. We've seen everything from Ferrari V8s to quad-turbo V12s dropped into its engine bay in the past. This swap, though, is something we haven't seen yet.
Zoom Garage built a Toyota 86 race car for the World Time Attack Challenge using the 5.0-liter S85 V10 engine from the E60-generation M5. With a little transmission wall cutting, the team was able to fit the six-speed gearbox from an E92 M3. In its current tune, the S85 produces 520 horsepower thanks to fuel pump and injector upgrades, as well as E85 fuel.
According to Zoom Garage, the V10 is just 44 pounds heavier than the stock engine thanks to the inclusion of a dry sump oil system. Weight distribution is 52 percent front, 48 percent rear. That motor is no joke—I own an E60-generation M5, and the best part about it is the engine, by far.
Unsurprisingly, all that power in such a small chassis makes for one hell of a time attack car. Watch for yourself as High Performance Academy walks you through the build.
