Hello, I have a 2014 BMW 328i (F30, N26 engine) with a stage 2 boot mode tune. I have done almost all the bolts on upgrades I can. But alas I come to you guys for assistance because after multiple misfires and cylinder four, we have broken down my engine to the block and determined that I seem to have blown my piston ring.
I have plans to rebore the block to a slight overbore and outfit it with forged Pistons.
I'm asking you guys if you can help me find a source for forged Pistons for N26 and/or verify compatibility on these ones:

I'm also asking if there is anything I should know before we rebore the block, like for example if it is plated with anything that can't be replaced or if I need to sleeve it.
I would also love any recommendations on parts I should upgrade/swap out while the engine is broken down.
