Tuner Special: G-Power M3 CSL

BRUNSBUETTEL, Germany

G-Power, the BMW specialist, has a solution for Bimmer owners and enthusiasts who believe Munich is missing the boat on performance options.

The tuner has begun retrofitting the 5.0-liter V10 from the M5 into the previous-generation M3 and says it will be happy to do the same for your current E91 3 Series coupe, X5 or Z4.

If that doesn't wet your pipes, G-Power says it is also working on a twin-supercharger kit for the V10, which in normally aspirated mode delivers a mere 500 horsepower. Two variants in G-Power's pipeline are said to produce 640 and 750 hp, respectively.

In the recent E46 conversion, G-Power coaxed a bit more power from the stock V10, nudging output to 550 hp and torque to 412 pound-feet. Zero-to-60-mph acceleration is trimmed from 4.8 to less than 4.2 seconds, while top speed leaps from 177 to 208 mph.

Underpinning the car is a KW Automotive suspension, complemented with 21-inch G-Power Silverstone Diamond wheels.
