What's the most indestructible car engine ever built? Meet Toyota's legendary 2JZ straight-six from the 1990s. While it made just 280 horsepower stock, this beast was so overengineered with its forged crankshaft and cast iron block that tuners discovered it could handle over 1,000 horsepower with minimal mods. It powered the iconic Supra and became famous through Fast & Furious movies. Decades later, it's still the go-to engine for insane horsepower builds. Some legends just refuse to die. | Aut
