mid 20's :o your not trying hard enough,,,,,,,, hahahaha
Echo whats been said above, regular oil changes (3k), keep on top of servicing, if an issue arises don't try to drive through it, drive very gently and off boost and get it looked at, and if you decide to mod it then find a decent tuner and stick with them, you'll get varying opinions of who's good and bad so its a bit of a mine field
