This is like asking if you prefer a leather jacket or a tailored suit. The 2JZ is the legend—the OG, the wild child. It’s heavy, old-school, and needs boost to sing. But its potential is limitless. You can build a 2JZ to run on rocket fuel (slight exaggeration).
The B58 is the modern marvel. It’s lighter, more efficient, and comes with a freaking 8-speed automatic that shifts faster than you can blink. It also has a better power curve right out of the box. No waiting for spool, just instant grunt.
But here’s the trade-off: the B58 is scary reliable but not as overbuilt as the 2JZ. You can’t just dump 1,500 horsepower into a stock B58 and expect it to smile. It’ll break, probably in a spectacular way. The 2JZ would just laugh and ask for more.
What About the Supra’s Racing Heritage?
Oh, you want that story? The Supra’s engine lineage goes back to the 1JZ and 7M-GE. Basically, Toyota has been refining the inline-six since the 1980s. They nailed it with the 2JZ, then took a 20-year nap, and woke up with a BMW.
Toyota Supra 2026 Engine Specs
Some purists hate this. They say it’s not a “real” Supra because it doesn’t sound like a 2JZ. And they’re not wrong—it doesn’t. It sounds more like a German mill, all tech and precision. But a few people actually prefer it. It’s an acquired taste.
Quick trivia: The MK4 Supra’s engine was also used in the Toyota Aristo and the Lexus GS300. So, it wasn’t even exclusive to the Supra. The 2JZ was everywhere. Meanwhile, the B58 is in the BMW 340i, 440i, X3 M40i… and now the Supra. It’s a shared platform, baby.
