The car is a 2004 NB2 VVT.
I bent a rod back in April/May and am now finally getting to tearing the engine apart. Cylinder 1 appears to be the one that has a bent rod (at least the MOST bent rod haha). The cylinder walls all look very clean and even across cylinders 1-4.
I plan to go to a forged rods only built and am trying to assess if this block/pistons look salvageable.

I thought it look really good, but then I noted a bit of curious wear on the bent rod's piston backside. It has me scratching my head until my friend mentioned that it may be from rubbing against the crank (counterweight) due to the shortened stroke.
Looking at the crank, I can see exactly what he is talking about.

I rubbed my finger across the crank's counterweight area and it is smooth, not much of a difference from the rest of the area.

My question is, does this block and pistons look still usable?
Am I going to have issues of balance or other if it goes back in? I may work with a machine shop once I install the new forged rods and perhaps they can help balance?
I am really new to this level of advanced engine work, so go easy on me please :P

So the rods and pistons are obviously junk, and you can have your entire rotating assembly balanced once everything is purchased. That includes crank bolt, crank pulley, crank sprocket, pistons, rods, flywheel, and pressure plate. Those counter weights are where they remove material from, with a drill.

 

Nice banana!

The piston cracked, too!
