Thanks to bboyalan's advice, I stopped speculating and dove into the car to figure out what's actually inside.
It looks like the car has a 0.75mm overbore (which puts it at 91.85mm?)
Im not the most mechanically knowledgeable, but i've read about some concerns of wear due to excess heat from thinner cylinder walls.
Since I already plan on taking the engine out, please share your thoughts on sleeving and new pistons vs cleaning up what's already in here?
Money aside, what's the smartest choice for reliability? Thanks for your time everyone
