In the world of Toyota performance engines, few names evoke as much excitement as the legendary 2JZ-GTE and the modern B58. Both engines have powered some of Toyota’s most impressive sports cars, but they represent two different eras in engineering. Whether you’re a fan of the old-school, bulletproof nature of the 2JZ or the high-tech efficiency of the B58, both engines have a unique appeal. In this post, we’ll break down the similarities and differences between these two powerplants to help you understand what makes each one special.
A Brief Overview of the 2JZ-GTE
The 2JZ-GTE is one of the most revered engines in automotive history, renowned for its durability, modifiability, and sheer performance potential. Originally introduced in the early 1990s, the 2JZ-GTE powered the Toyota Supra MKIV, a car that quickly became an icon thanks to its role in the tuner world and pop culture. In reality we think Fast and the Furious propelled its popularity.

Specs at a Glance:
• Displacement: 3.0L Inline-6
• Configuration: Twin-turbocharged
• Power Output: 276 hp (Japan) / 320 hp (USA)
• Torque: 318 lb-ft (USA)
• Years Produced: 1991-2002
• Fuel System: Sequential fuel injection
What makes the 2JZ-GTE a tuner’s dream is its incredible strength. Built with a cast-iron block, forged internals, and a low compression ratio, the engine can handle massive power increases with relative ease. It’s not uncommon to see 2JZ-powered Supras pushing 1,000+ horsepower with the right modifications. The engine’s twin-turbo setup, combined with Toyota’s focus on reliability, made it an ideal platform for high-performance tuning.
Rumor has it that Toyota over built the engine. The supra was supposed to have much more horsepower than what the production model had.
A Look at the B58 Engine.
Fast forward a couple of decades, and Toyota introduced the B58 engine—a modern inline-six that powers the new Toyota Supra (J29/DB). Co-developed with BMW, the B58 reflects the modern trends of efficiency, emissions standards, and technological advancement. While it may not have the legendary status of the 2JZ just yet, it’s already proving itself as a highly capable and sophisticated engine.
Specs at a Glance:
• Displacement: 3.0L Inline-6
• Configuration: Single twin-scroll turbocharger
• Power Output: 382 hp (USA, 2021+ models)
• Torque: 368 lb-ft
• Years Produced: 2015-present
• Fuel System: Direct fuel injection
The B58 is part of BMW’s modular engine family, designed to offer both performance and efficiency. It comes with an aluminum block, which makes it lighter than the 2JZ, and advanced tech like variable valve timing, direct injection, and a twin-scroll turbocharger. While it may not have the same tank-like durability as the 2JZ’s cast-iron block, the B58 is built with today’s high-performance, fuel-efficient needs in mind.
Performance & Modifications.
When comparing performance, the 2JZ-GTE and B58 are both strong contenders, but they shine in different ways.
• 2JZ-GTE: As a performance icon, the 2JZ-GTE is loved for its ability to be modified well beyond its stock power output. With stock internals, enthusiasts can push 800hp, and with upgraded components, it’s not uncommon to see 1,000+ hp builds. The aftermarket support for the 2JZ is vast, and it’s a go-to engine for drag racing, drifting, and high-power street builds.
• B58: The B58 may not have the years of proven performance mods like the 2JZ, but it’s quickly earning a reputation for being a tuner’s engine. Its more advanced fuel system and turbo design allow for significant power gains with basic modifications like a tune, downpipe, and intake. Tuned B58s have been known to easily hit 450-500 hp with relatively simple mods, making it a strong contender for modern performance enthusiasts. However, long-term durability at extreme power levels remains a point of debate among tuners.
Tuners are still pushing the boundaries of the B58, achieving 900+ hp on stock internals. Our team leader has a G20 daily driver with 683 whp. As of today, it has been completely reliable.
Taking about reliability.
• 2JZ-GTE: The 2JZ’s cast-iron block and overbuilt design give it a clear edge in reliability, especially when tuned for high horsepower. Known to take a beating on stock internals, this engine’s durability is one of the reasons it’s still sought after 20 years after production ended.
• B58: While the B58 is no slouch in terms of reliability, it’s a more complex engine, with modern electronics and emissions equipment that could be points of concern in the long run. That said, it’s considered one of BMW’s more reliable engines, with a good track record for daily driving and moderate performance builds.
Technology
This is where the B58 pulls ahead. It’s a much more advanced engine, incorporating modern technology like:
• Direct injection: For better fuel atomization and efficiency.
• Variable valve timing (VANOS): For optimized power delivery across the RPM range
• Single twin-scroll turbo: Offering quicker spool times compared to the 2JZ’s older twin-turbo setup.
While the 2JZ-GTE remains a mechanical marvel of its time, the B58 brings cutting-edge advancements that make it more fuel-efficient and responsive in stock form.
Verdict: Old School vs. New School.
In conclusion, choosing between the 2JZ-GTE and B58 depends on your priorities:
• If you’re after a bulletproof engine with near-unlimited aftermarket support and a proven track record for extreme performance, the 2JZ-GTE is your go-to. It’s an old-school legend that refuses to die and is perfect for those who want to chase high horsepower with confidence.
• On the other hand, if you want a modern engine that balances performance with efficiency, has tons of tech, and can still deliver serious power with minimal modifications, the B58 is the right choice. It’s the future of Toyota performance, offering a refined yet powerful experience right out of the box.
Both engines are fantastic in their own right, but they cater to different types of enthusiasts. Whether you’re nostalgic for the 90s glory days or excited about the next generation of performance cars, Toyota has provided us with two truly exceptional engines to enjoy.
If you are a piston head like us, have both.
