How to Turbocharge the BMW 3 Series


1. Place your BMW 3 Series on a lift or elevate it on four jack stands. This will allow you to access the underside of the car where the turbocharger will need to be installed.
2. Install the turbocharger after the exhaust headers and follow the installation instructions for the specific turbocharger unit that you've purchased.
3. Route the boost lines from your turbocharger kit from the turbo to the components such as the blow-off valve, which release excess turbo pressure between uses.
4. Complete the installation of the turbo by installing an aftermarket engine control unit or having a custom tune done by a tuning shop.
5. Replace the factory exhaust with a larger exhaust system that will allow combusted to exit the engine faster and will accommodate the additional horsepower produced by the turbocharger.
