Arguably, the most famous BMW engine ever produced is the S65B40 4.0-liter V8 which built its brand upon the equally famous and praised E92 M3. Derived from the S85 V10 engine first used in the E60 M5, the S65 shares the same basic architecture and aluminium construction, and was chosen as International Engine of the Year for the 3.0 to 4.0 L category in 2008, 2009, 2010, 2011 and 2012.

Its 414hp is a nice power number, but it isn’t the important one. The important number is 8,450, which is the number of revs that the S65 redlines at. A V8 that revs at nearly 9,000 rpm is a wonderful thing to behold.

Now, this legendary engine makes its way into a quite unique model – the 328i Sports Wagon. Left untouched, this engine is already pretty powerful but the current owner has decided to add an ESS VT2-625 supercharger for a total power output of 625 hp.

To complement the engine, the car also includes a new radiator, oil cooler, power steering cooler, DCT cooler and a header-back Akrapovic Evo titanium exhaust system.

The other performance and aesthetic modifications start with the OEM Porsche dark gray paint job. Cosmetic mods include Forcewerkz front lip and side skirts plus a Varis rear diffuser. A KW V3 coil-over suspension has been fitted to lower the vehicle, and the car’s new Turner Motorsport aluminum skid plate should offset most problems caused by rogue curbs and steep driveways. It also comes with 18-inch Volk TE37SL wheels wrapped in track-happy Toyo Proxes R888 tires.

The car had about 45,000 miles on it before the swap was performed and the donor M3 had 63,600 miles on it. The BMW’s odometer currently sits at 66,150 miles.

Best part is that you can actually bid on the car today, so feel free to head over to Bring-a-trailer to see this exciting BMW.
