what is the difference on 2ZR-FE engines?
hello, I just purchased a yaris! I've been doing some research on what needs to be done for faster driving. i'm a big fan of rotrex superchargers, but I have not found anything on here about anyone using one on the 1nz, but I've found kits in japan. i'm not interested in a blitz s/c because the efficiency is not there on the screw s/c imo. I've seen a few turbo kits, and they seem to work well. I came across the engine swap posts, but they were pretty vague and there seemed to be just a bunch of talk.
so, the 2zr-fe seems to be a good swap. the issue I have is all posts say XD is the swap, but it has the lowest output numbers. what is the difference between XD and corolla 2ZR-FE? is it just exhaust manifold and other bolt-ons, or is the block physically different? I see there is a 10hp-ish gain from going with a corolla engine. why is the XD pushed so much when it's the weakest output? thanks for any info. j. |

The part numbers for the block assembly are the same for the corolla and xd, so the 6% difference in hp and less than 2% difference in torque likely are a product of the differences in intake and exhaust layouts.
Having driven supercharged, turbo, and 2ZR swapped Yaris, I would definitely say that the 2ZR is the best choice for a daily driver, if you can track one down reasonably.

the XD and corolla/matrix blocks are identical. It is the result of intake/exhaust design due to the room. There was talk a long while back regarding ECUs that may have a factor, but the topic has hit a dead end. Also, the 2ZR does have a more limited aftermarket than the 1NZ, but you can be happy with ~140 engine hp after simple addons. (add another good chunk of hp if the RPM midpipe directly fits into a yaris)

there's also the 2ZR-FAE engine on select usdm 2014+ corollas that have more power (higher compression+valvematic), which is a very unknown thing in terms of swapability.

im leaning more towards modified head, and extra wiring...could be changes to the block to fix potential issues found in the regular 2zr
