The 1NZ-FXE is the earliest 1.5 L (1496 cm³) version built in Japan. Bore is 75 mm and stroke is 84.7 mm. This applies also to the 1NZFE.

The 2NZ-FE is a 1.3 L (1298 cm³) version built in Japan. Bore is 75 mm and stroke is 73.5 mm, with a compression ratio of 10.5:1.

The part #'s have to be different.

This website has piston heads and rods for 1NZ-FE engines that might be suitable.
Can someone please tell me if these are suitable cause I'm thinking about doing it to my own yaris.

Those pistons will not work on the 2NZFE. The bore size is correct but the compression height is not correct. The 1NZFE is 84.7mm stroke & the 2NZFE is 73.5mm stroke.
