2JZ vs RB26. A debate that as wreaked havoc on the internet since the days of dial up until now. Both the Toyota 2JZ and the Nissan RB26DETT are arguably the most iconic Japanese performance engines to ever be produced.
To this day both engines are seen as popular and sought-after swaps for a myriad of project cars. When someone really wants to get spicy, they’ll even consider mixing brands by dropping an RB26 in a Toyota or a 2JZ in a Nissan.
Though when it comes down to it, in the debate of 2JZ vs RB26 which engine is actually better? The thing is, both mills have a lot in common. They’re both in-line six engines, they’re similar in size (the 2JZ is a 3 liter engine and the RB26 is 2.6 liters), and both engines came from the factory with two turbos and roughly 280 horsepower (in Japan).
With so many similarities, it would require someone with far more experience than a keyboard mechanic to really offer any valuable insight on the 2JZ vs RB26 discussion.
Luckily, Toyo Tires spoke with Kenji Sumino, President of GReddy Performance to get his expertise on the matter in a new video. Kenji has spent decades working with both engines so if anyone is qualified to speak about it, it’s him.
In the video below Kenji goes over some of the technical nuances of each engine and shows off some high level examples in the Evasive Motorsports FR-S (piloted by Dai Yoshihara), a JDM right-hand drive JZ80 Toyota Supra, and several R32 Skyline GT-Rs.
Kenji also addresses some of the most common questions like which engine is more expensive to build, and which one has more power potential.
It is all pretty interested stuff if you want to hear it straight from the mouth of an expert. The video is just shy of ten minutes so it is a really easy watch too. Check it out below!
