Here’s a delicious little E30 package. It looks perfectly stock right down to the 14-inch basketweaves, and the engine swap even shares the original displacement. Yet instead of the M20B25 it came with, it’s now the M50B25TU – the first update for the 2.5-liter inline-6s available in the E34 525i and E36 325i in the mid-90s. The addition of VANOS improved low-end torque, and even without a power bump it’s still producing E30 M3 levels of power. It may not be the racy swap we’re used to seeing in E30s, but in some ways that’s what makes it perfect. The car will maintain its standard composure, driving dynamics, and low-key appearance while providing plenty of power to keep up with modern cars and breed smiles like rabbits in the hills.
