The Benefits of an RS4 Conversion

The RS4 is the highest level of performance for the Audi A4 series. It comes with a more powerful engine, improved suspension, and upgraded brakes. By converting your A4 B8 to an RS4, you'll enjoy a significant boost in performance and handling, making your driving experience more thrilling and enjoyable.

Improved Engine Performance

The heart of the RS4 is its engine, which is a 4.2-liter V8 that produces 450 horsepower and 317 lb-ft of torque. By comparison, the A4 B8's engine is a 2.0-liter turbocharged four-cylinder that produces 211 horsepower and 258 lb-ft of torque. With the RS4 conversion, you'll get nearly double the horsepower and a significant increase in torque.

Upgraded Suspension

The RS4 comes with an upgraded suspension that includes stiffer springs, dampers, and anti-roll bars. This setup provides improved handling and better cornering performance, making your car feel more planted and stable on the road.

Improved Brakes

The RS4 also comes with larger brakes that provide better stopping power and improved fade resistance. This is especially important if you plan on taking your car to the track, where you'll need to brake hard and frequently.

The RS4 Conversion Process

The RS4 conversion process involves several steps, including engine and transmission swap, suspension upgrade, and brake upgrade. Here's a breakdown of the process:

Suspension Upgrade

Once the engine and transmission are in place, the next step is to upgrade the suspension. This involves replacing the A4 B8's suspension with the RS4's stiffer springs, dampers, and anti-roll bars. This step requires some welding and fabrication work to install the new components.

Brake Upgrade

The final step in the RS4 conversion process is to upgrade the brakes. This involves replacing the A4 B8's brakes with larger RS4 brakes that provide better stopping power and improved fade resistance. This step requires some brake line modification and installation of new calipers and rotors.

The Cost of an RS4 Conversion

The cost of an RS4 conversion can vary depending on several factors, including the condition of your A4 B8, the cost of the donor RS4, and the labor costs involved in the conversion process. On average, you can expect to spend between $30,000 and $50,000 for a complete RS4 conversion.
