1. Stock engine: The original 1.5-liter air-cooled engine is a popular choice for those looking to maintain the original character of their Beetle. It is simple to maintain and relatively fuel-efficient, but it also produces only 40 horsepower, which is not very powerful by modern standards.
2. Upgraded stock engine: For those who want a bit more power without straying too far from the original design, there are a number of ways to upgrade the stock engine. Common modifications include installing a larger carburetor, a performance camshaft, and a free-flow exhaust system. These modifications can increase power output to around 60 horsepower.
3. Swap engine: For those who want the most power out of their Beetle, a full engine swap is the best option. Popular swap engines include the Porsche 356 engine, the Subaru EJ22 engine, and the Volkswagen EA827 engine. These engines can produce over 200 horsepower, which can transform the Beetle into a very fast car.
4. Electric conversion: For those who want a completely emissions-free Beetle, an electric conversion is a great option. Electric motors produce instant torque, which makes them very fast and responsive. There are a number of companies that offer electric conversion kits for the Beetle, and the cost of these kits has come down significantly in recent years.
