The legendary 2JZ 3.0-liter inline-six engine is in a big part responsible for the Supra A80’s fame, especially in range-topping 2JZ-GTE twin-turbo guise.
Interestingly, the new BMW-sourced 3.0-liter turbocharged inline-six (codenamed B58M30 01) produces a similar amount of power and torque as the 2JZ-GTE: 335 hp (340 PS) and 365 lb-ft (494 Nm) compared to 320 hp at and 315 lb-ft (427 Nm).
So does that mean the 2020 Toyota Supra’s engine has a similar shot at fame as the 2JZ-GTE? It’s obviously too early to tell, but Engineering Explained has put together a very detailed video which points out that the BMW engine has a closed-deck block that allows it to take high amounts of boost without any concerns. It’s a similar design adopted by some high-powered custom builds from Subaru.
While that’s a good sign for those who want to squeeze more power from the engine, the fact that it has an alloy block as opposed to the 2JZ’s indestructible iron block probably means the B58 won’t be able to take that much extra horsepower. Something that will also raise some eyebrows in the aftermarket world is the fact that the B58 has spray-on cylinder liners which don’t allow re-machining and sleeving.
There are many more interesting things you can learn about the 2020 Toyota Supra’s 3.0-liter engine, such as the way twin-scroll turbocharging works. The video dissects the new Supra’s six-cylinder unit in great detail and makes for a very interesting, and unusual, viewing.
