Not sure if this has been discussed before. Why doesn't Toyota use this awesome engine in any new production cars anymore? Coming from a Supra before my Lexus I love this engine to death. We all know it was lightyears ahead of its time when it came out. Just wondering why did they decide not to use it anymore?

this was discussed in another thread
2JZ-GTE and the whole 2JZ-GE series are not so fuel efficient anymore in today's standards
plus iron blocks arent that necessary now with composite metal engine blocks
now toyota wants a fuel efficient and green image attached to them
so from now on, we will be able to see a lot of V6 3.5L paired with Synergy Drive technology to give more performance than the 2JZ-GTE

There are many new motors that are superior to the 2JZ-GTE these days, in terms of fuel efficiency, and emission. For example, 2GR-FSE and BMW's N54 bi turbos motor.
long live 2JZ

The engine wasn't lightyears ahead of its time. It was just a very very good design. It was based on the strongest of the strong workhorse motors in work vehicles in japan. It is able to handle a ton of power without breaking. Compare the head and airflow capabilities to a modern motor like a K20 head or a E46 M3 motor, etc and it pales in comparison. Not in power output potential blah blah... but if you know anything about how an engine works, you'll know what I'm talking about.
REALLY? Thats awesome about the rods; because the 1jz and 2jz have the SAME RODS. Crank is different along with a different deck height to make the displacement difference.
In the end, the 1jz is nothing but a 2jz with .5L less displacement. It flows less air than a 2jz therefore has less potential power. In stock form it is able to rev higher and have similar airflow; but in the end, it flows less air than a 2jz because of the displacement, therefore it won't make as much power. The heads are too similar to make as much difference as most 1jz fanboys fantasize about. In fact, the 2jz heads (GTE and GE) both flow more. The 1jz-gte head has higher port velocity, but that is from being more restrictive; fine for smaller turbos... but.... yeah you can complete the sentence

But that takes NOTHING away from the motor itself. Its very affordable and has a great powerband for a lightweight car.... namely my 240sx
