I came across a 2012 Maxima engine, but unfortunately it has a burned-up bottom end. I also have a good 2003 VQ35DE, and I was wondering if there’s any benefit to running a fresh set of 2012 pistons in the 2003 block, while keeping the ’03 rods.
For reference, the 2012 piston is on the left.

I got access to a scale and recorded the following component weights:
Pistons
- 2012: 383.4 g
- 2003: 396.4 g
Wrist Pins
- 2012: 99.2 g
- 2003: 105.7 g
Connecting Rods
- 2012: 590.0 g
- 2003: 589.3 g
The combustion height is the same for both pistons.
