Engines That Deliver Thrills for Years
Some engines aren’t just powerful, they’re unforgettable. They combine raw performance with engineering finesse, delivering the kind of sound, response, and reliability that keep enthusiasts hooked long after the new-car shine fades.
These are the engines that don’t just perform well on paper; they create an emotional connection every time you press the throttle. From high-revving screamers to torque-rich powerhouses, here are the engines that continue to deliver thrills for years.
1. Toyota 2JZ-GTE (Supra Mk4)
Few engines have achieved mythical status quite like Toyota’s 3.0-liter twin-turbo inline-six from the legendary Mk4 Supra. The 2JZ-GTE is famous for its ability to handle massive amounts of boost often surpassing 800 horsepower on stock internals.
Beyond its tuning potential, what really sets it apart is its indestructibility. Owners have logged hundreds of thousands of miles with regular oil changes and proper maintenance.
Its iron block and overengineered internals make it one of the most durable high-performance engines ever built. It’s no wonder tuners and drag racers still hunt for 2JZs 30 years later.
Toyota’s Supra story begins in the late 1970s, when the nameplate branched off from the Celica as a more muscular version of the popular coupe. These early Celica Supras featured longer wheelbases, wider stances, and more powerful six-cylinder engines, though they still carried much of the Celica’s DNA.
That changed in 1986, when Toyota dropped the Celica name altogether and positioned the Supra as a standalone performance car. By the time the fourth-generation model debuted in late 1992, the Supra had evolved into a completely different beast, sharing as much with Toyota’s entry-level sport compacts as it did with the humble Paseo.
The biggest reason for that transformation was the introduction of the factory turbocharged 2JZ-GTE engine, an inline-six powerplant that would go on to achieve near-mythical status.
Even decades later, professional tuners and motorsport teams still seek out the 3.0-liter 2JZ-GTE for its ability to handle astonishing levels of power with minimal modification. Few production engines before or since have demonstrated such potential straight from the factory.
In the U.S., the 2JZ-GTE, a clean-sheet design entirely separate from the previous Supra’s 7M-GTE—was available exclusively in the 1993–1998 Supra Turbo models. In Japan, it debuted in 1991 under the hood of the Toyota Aristo and continued to power select Supras until the model’s discontinuation in 2002.
There’s also the 2JZ-GE, a naturally aspirated sibling that shares the same short block and nearly identical rotating assembly but with higher compression and around 230 horsepower.
While the 2JZ-GE found homes in non-turbo Supras and cars like the Lexus IS300, GS300, and SC300, enthusiasts tend to avoid it, as it lacks the immense tuning potential and raw performance that make the 2JZ-GTE legendary.
