1nz-fe and 2nz-fe
Hi, i would like to know if the height of the engine block are the same and if it is possible to put a 1nzfe crank shaft in the 2nzfe engine to gain same power. Thanks.

Why not just swap the whole 1NZ block?

Why would a stock crank swap increase hp? |

Because commonly different strokes are accommodated in the same block by using different cranks and pistons to reach the same deck height. That's what he's asking, if the 2NZ-FE block can be stroked to make a 1NZ-FE engine out of it. A reasonable question.

If the blocks are the same, you'd probably need crank, rods, and pistons to make it work. Then the matter of bearings, rings, re-hone block. It would be much simpler to swap the block for a 1NZ.

The 1nz versus the 2nz isn't like the DSM 4G6-series engines where they had a variety of bores AND strokes (1.6, 2.0, and 2.4 blocks were all mix-and-match, crank adjusted it by 0.3, block/pistons by 0.1 per step) so mix-and-match cranks had a use to avoid dealing with re-boring a block.
The Yaris blocks? Eh, just get a complete crate used engine to change between the two, you're only adjusting the stroke and the bore's the same between the two.
