Can I replace the engine of my Audi 80 1.6 without having to modify the car?

I want to swap out my current engine for a more powerful one, but I'm not sure if it's a simple plug-and-play process or if I'll need to make modifications to the car itself.

Yes, you can replace the engine without having to modify the car, as long as the new engine is compatible with your Audi 80 model. It's important to research and double check compatibility before purchasing a new engine.
