We have new cars, new technologies, new upgrades and generally new performance available to us at any moment. But what happens when you want to fit some of those to an older car?

This is exactly what G-Power have done. On the verge of a new BMW M3 being introduced with the F30 generation, they’ve turned their attention to the E46.

They’ve kept the same basic 3.2 liter straight six cylinder engine but beyond that I very much doubt things look familiar to anybody.

Using a supercharged kit, upgraded intakes, a revised exhaust and a remapped ECU that engine now produces 450 horsepower 339 lb-ft of torque.

For those who aren’t keen on “old” car specs, that’s a boost of 107 horses and 70 lb-ft of torque over the original.

The result of this upgrade is fairly easy to spot. According to the German tuner it now takes the E46 M3 14.6 seconds to complete the sprint from 0 to 124 mph.

Since they’ve also been kind enough to remove the top speed governor, the G-Power E46 BMW M3 can now hit a maximum of 186 mph.

In order to reign in the power, an adjustable coil-over suspension goes on together with some upgraded brakes. The latter are so ferocious they need 20 inch wheels to fit over the calipers.

Michelin Pilot Sport tires are the last technical upgrade we get to see on the G-Power E46. Otherwise, they’ve kept things clean and tried to make the car look as much as possible like the CSL version.
