So my '07 STi has about 70k on it now (bought it last summer with 58k). I commute from San Jose to Sacramento a few times a month, and 30 mins there/back to work everyday.

I've been thinking about whether or not to do these upgrades I've been wanting (18g turbo, injectors, fuel pump, pro tune) -- but my question is (and it may be dumb/obvious) - who has STI's here that is running them with much higher than stock power, with over 100k miles, etc? Because I will definitely be hitting that mileage in no time, and I kind of want reassurance the car will keep lasting.

Anyways, any input appreciated.

leakdown test and oil analysis sounds like a good place to start. I would say talk to whoever is going to tune the car and ask this question. Not sure of the 07 sti specific problems though. Oil pickup or something like that.

^this..

the mods you are looking to do are great upgrades! lot of people run the set up on the daily. heck i used to do that for over 40k miles and just ended up selling it because i decided to get something different. Other than that.. it was fast, reliable, and safe.. just make sure you get that protune and you'll enjoy it a hell of a lot more. some some bookshelf cobb ap map.

Thanks for the infos. Everything I've been hearing says it should stay reliable for a long time given I handle simple maintenance.
