The 2002 Toyota Echo has two different starters because the US-made Echo and Japanese-made Echo have different engines. The US-made Echo has a 1.5-liter engine, while the Japanese-made Echo has a 1.0-liter engine. The different engines require different starters because they have different cranking power requirements.
