Engine swaps are not exactly rare in the BMW community. We’ve seen plenty of I6, V8, and even V10 installations, and we know how much purists love a Bimmer with a Chevy LS small block under the hood. The one featured in this entire video is a BMW, and it’s especially neat considering the size of the mill versus the car it ended up with.
The E46 M3 is not a slow car by any means. It has a 3.2-liter inline-six engine – the last evolution of the S50 motor – producing 338 horsepower and 269 pound-feet of torque. In the past, it was available with either a six-speed manual gearbox or a six-speed automatic manual transmission by Getrag. It’s as respected now as it was coveted when new, but with so many more powerful engines floating around, why not add a few more hp (and cylinders) for track day fun?
That’s what the owner featured in this video did with his black M3. The straight six is gone, replaced by a 5.0-liter V10 sourced from the E60 M5. Remember, that’s BMW’s first and only version of the V10 to date and in this program, it delivers 500 hp and 384 lb-ft of torque in factory form. Arguably the best part of the equation is that the unit is mated to the E92’s dual clutch transmission.
A few minor mods, including a new engine map, result in an output of around 520 hp for this particular M3. After a brief introduction, the black coupe is taken for a lap around the Nurburgring. And dare I say it, from the very beginning, it’s an absolutely crazy ride. In addition to being incredibly fast – we can see it outrunning some of the world’s leading performance cars with ease – it also sounds absolutely incredible.
This isn’t the first BMW V10 project we’ve seen. Not to forget the range-your-own M5 wagon, boasting a 10-stroke engine and a manual gearbox. And in November 2022 there was a good M3 (E30) with an improved 625-hp version of the M5’s V10.
