Someone was mad enough to replace the original engine that powered this E46-generation BMW M3 with an 8.3-liter V10 from the Dodge Viper.
There aren’t any videos on YouTube yet of this beast being unleashed on a proving ground where it gets to validate that this is a monster on wheels. But that doesn’t rob this particular E46-generation BMW M3 from being one of the insane examples of engine swapping. Why so? Because under that hood, it has a gargantuan 8.3-liter, 500 hp, V10 engine that once belonged to a Dodge Viper.
Posted on Youtube by Giorgi Sulava, there are two videos of this BMW M3 E46. One shows the car before the builders slapped on the Rocket Bunny Pandem body kit to give the creature a more terrifying stance. There is a hole cut into the hood to accommodate the Dodge powerhouse and there is a quick glimpse of the Viper-powered M3 speeding away from the garage. That sound is glorious!
The second video shows the BMW M3 shows the progress being made. The body kit is on and instantly bestows the car with a frightening look. The hole on the hood gets a cover to shield the engine and though it seems to be a temporary job done with pure function-over-form in mind, the industrial look of it kind of grows on you.
There is plenty of work left in the interior as the wires and cables are all over the place. The spartan interior has the Viper dash and a cluster of meters to stare at. An orange roll cage is in place. Obviously, these guys are prepared for the worst-case scenario in the event of the driver failing to control the power that the Dodge engine will churn out.
Then there is the third video from BMW My Life which presents the finished form of the Viper-powered E46 M3. It’s finished in bright green, with the hole on the hood becoming a part of the design as the Viper engine’s source of air. Plus, it’s not like there was a lot of real estate inside the M3 engine bay which used to house a naturally-aspirated 3.2-liter inline six-cylinder block once.
There is no word out on the transmission yet. But that gearbox will be having a hard time harnessing and delivering the sheer might of the V10 in a controllable fashion to the rear wheels of this BMW M3.
