What size engine can you put in your 69 vw beetle?

The largest engine that can be installed easily is the 2.0L engine from the Volkswagen LT van, which produces 115 horsepower (86 kW) and 130 lb⋅ft (176 N⋅m) of torque. This is significantly more power than the original 1.5L engine, which produced only 40 horsepower (30 kW) and 75 lb⋅ft (102 N⋅m) of torque.

With some modification, it is also possible to install an even larger engine, such as the 2.5L engine from the Audi 100 or the 2.8L engine from the Volkswagen VR6. These engines produce even more power and torque, making the Beetle even faster and more fun to drive.

However, it is important to note that installing a larger engine in a Beetle will require some modifications, such as upgrading the brakes and suspension, as well as modifying the engine mounts and transmission. It is also important to consider the weight distribution of the Beetle, as adding a larger engine can make the front end heavier and affect the handling.

Overall, installing a larger engine in a Beetle can be a fun and rewarding project, but it is important to do your research and make sure you have the necessary skills and resources before attempting this modification.
