Are 1995 and 2005 VW Jetta motors interchangeable?

The engines in the 1995 and 2005 Volkswagen Jetta are not interchangeable. The 1995 Jetta uses a 2.0-liter inline-four engine, while the 2005 Jetta uses a 2.5-liter inline-five engine. The mounting points for the two engines are different, and the electrical connectors are not compatible. Additionally, the 2005 Jetta uses a different transmission than the 1995 Jetta, so the engines cannot be mated to the same transmission.
