Here’s exactly what you’ll need to add a turbo to a naturally-aspirated engine.
As much as your local car club might like you to think it, turbocharging a naturally-aspirated car isn’t simple. There are a lot of different thing you’ll need to do to add forced induction to a car that didn’t come with it from the factory. Thanks to this neat explainer video, we learn exactly what you’ll need to change.
For example, the builder of the wild twin-turbo Chevelle SS drag racer shown above had to worry about cutting giant holes in the hood!
Jason Fenske of Engineering Explained put together a video pointing out all of the modifications you’ll need to make to your car when preparing to turbocharge it. These mods aren’t for additional power, but rather to ensure the engine and drivetrain can handle the extra boost.
Of course, adding a turbo means you’ll need to think about compression ratio, ECU mapping, and fuel delivery. But you might not realize you’ll also need to consider your car’s cooling capacity, and if you’re really adding a lot of power, your clutch’s ability to get it to the ground.
But those are only a small portion of the items that need addressing when when you slap a turbo on your car. Watch for yourself to learn more.
