Thanks largely to its screaming, naturally-aspirated 3.2-liter inline six-cylinder engine, the E46-generation BMW M3 is considered to be one of the finest cars ever produced by BMW’s M division.

Not satisfied with the powertrain’s standard 338 hp, an E46 M3 owner in the country of Georgia has ditched the inline-six in favour of arguably the most obscene production car engine from the United States; the 8.3-liter V10 of the Dodge Viper.

We’re not sure what transmission has been mated to this animalistic, 500 hp engine but videos of the unique M3 do show that it is driveable and even has the same dashboard as the iconic American supercar.

Eager to show off the comprehensive modifications, the owner has painted the car bright green and had it fitted with a widebody kit from Rocket Bunny. A hole has also been cut in the hood to allow the huge V10 to breath.

Unless this engine swap has been done with the utmost of care, we can’t see this M3 being anywhere near as driveable as it once was. However, does that really matter if you can tell your friends you have a Viper-powered M3?
