Hello, I own a 2008 coupe si with 199K miles on it. I have own many hondas since the mids 90's, a 89 integra I had i got it to 355K miles and it would kept going but I got tired of driving it. Honda engines will last a long time as long as you stay on top of maintenance, specially if you're going to be pushing it hard. On the k20 engines I recommend every 80-100k miles or less if you push it often to change the timing chain, tensioner, and guides. The tensioner and guides wear out and you have slack on the chain, the chain will skip a tooth and then the engine will talk back to you.
