Changing the CR in and of itself won't necessarily make you have to sleeve etc. Since this is in the NA forum I'm going to assume you're staying NA...
That said our engine internals are good for 400hp+ stock, and thus I doubt you'd ever get that (especially with just a CR change), meaning I doubt you'd have to. The biggest thing you have to worry about is that the s2000 is already a major interference engine, and raising the CR is probably easiest done by making the head closer to the block (as opposed to getting a new crank, which increases piston speed, which increases the need for new piston/rod combo). This means you'll need different cam profile at the very least, if anyone even makes something like that.

The reason I was saying sleeping is I heard there was something on our cylinder walls that when you change pistons from stock you also need to do the same with sleeves. But I couldn't just change pistons and rods?

^ He's right. building an engine without a goal in mind results in lots of wasted money. If you're looking for a reliable way to just make more power, you really don't need to do anything to the engine. It would be far cheaper to do bolt-ons and EMS + tune.

It's gonna be a lot of work and deep pocket to pull that out of a 2.2L na. Try all bolt ons with ems. Go to 1000cc injectors with a walbro 255 fuel pump on e85 for starters. Or just buy ems and get your block built to a 2.7L. Inlinepro has a 106mm kit for 3.2k. You will need to sleeve your block. This option will cost money. Around $6-7k
