As far as extreme engine swaps and BMW E30s go, the V12-powered 350i we discovered back in 2007 no doubt takes the cake.
However, this 1989 3-Series sedan found for sale in Holland comes pretty close as the owner shoehorned a 4.4-liter V8 engine (M62B44) from a 1996-1998 540i E39 under its bonnet.
The eight-cylinder unit delivers 282-horsepower (286PS) to the rear wheels via a manual gearbox sourced from a V8-powered 535i E39.
In true Frankenstein style, the mix-and-match continues with front brakes from an E36 M3, rear brakes from an E36 325i, a radiator from the 324td, E36 leather seats, and a rear differential from an unidentified model.
If you live in The Netherlands, all this could be yours for €7,200 (US$8,900).
