RENNtech’s Resto-Mod 1998 Mercedes-Benz SL500

A “Resto-Mod” is a blend of old and new technology. This 1998 Mercedes-Benz SL500 RENNtech has been fully restored, maintaining the original classic styling while adding the latest technological advances in performance and comfort.

On the outside, this classic roadster received new custom metallic dark grey paint, an AMG aero package straight from the factory, and custom RENNtech wheels.

On the inside is where the real fun begins! The ’98 SL500 motor has been bored out 4 mm to 100 mm and stroked to 94.8mm transforming the old 5.0L powerhouse into 6.0 liters. For optimum results, a Bosch Engine Management System was installed together with a handmade wire harness for the engine. Software application and programming of the ignition and fuel required the tedious, time-consuming process of working from the ground up.

RENNtech engineered a custom intake manifold which was handmade by its highly talented fabricators, as well as all the necessary pipes and hoses, for the installation of 2 twin Borg Warner turbos. 400 plus fabrication hours later the custom exhaust and intake along with a water to air intercooling system complete with a heat exchanger lowered in the middle of the V fit perfectly.

To support the extreme power increase, both the chassis and driveline had to be reinforced. The convertible’s inherently soft chassis was upgraded to be stiffer for better handling, on a par with today’s’ convertible. A limited slip differential was added to improve handling and traction, the transmission was reinforced to handle the additional power. This SL500 is equipped with a fully adjustable sport suspension package allowing for the perfect ride height and damper settings in any environment. Finally, the unique custom ceramic brake package was designed, engineered and tested to work with the proper balance of the vehicle, to manage the increase in speed and performance.
