Boosted Yaris 100k miles service/repair/etc.

[47_MasoN_47]

Hey guys, my 2009 Yaris has just hit 93k miles. Around 50-60k of those miles are supercharged. I change the oil regularly, put new spark plugs in it when I boosted it, replaced the water pump sometime last year (and put all new coolant in). The water pump has been the only "major" repair I've done to the little car. Coming up on 100k though, I'm just curious as to if I should do any preventative parts replacement, etc. or if it's good to keep going until something breaks. I've heard most people say the timing chain never needs to be replaced and that sort of thing, but just want to make sure. It's been a good little car and I hope to get another 100k out of it before I have to buy something else.
