There is no doubt the Corolla will feature in the TRD range, but there is no way it will be a 1zz modified or not in the new model. Going forward, the 1zz lacks refinement, it's too (mechanically) thrashy in higher revs and has been around since 99 (Or earlier?) Given the competition out there, 1zz in the new Corolla is a bad move. I've now decided what I really want to upgrade to next (The question is when I actually can though), It's not a Toyota and it's a Diesel.
