The BMW M3 E9X series is old news now, but you have to say, it is still a very interesting car. The launch of the new M3/M4 models is very good news for the fans of this series, as the prices are starting to plummet. So you can get a good E92 or E93 for low money, and have it tuned to get crazy power with packages like this by Leib Engineering.

On the outside, BMW M3 E93 by Leib Engineering appears to be a standard M3 convertible with a set of 19-inch wheels from the 1M. But pop the bonnet and you are in for a surprise.

Leib technicians have used high-performance part from renowned BMW tuner G-Power, namely their ASA T1-523 supercharger system, to boost the output of the M3’s 4.0 liter V8 engine. Fuel pumps, ignition system, injectors, air intakes system, ECU, pretty much everything that was modifiable in this engine has been modified in some way. The result is 610 horsepower and 590 Nm of torque.

That is a significant gain over the standard M3, and people are going to notice, as there is a custom exhaust system with remotely controlled valve system. A KW dynamic damper system wraps up the tuning program.
