Default how does the wrx/sti 2.5 engine hold up?

Just wondering if anybody has over 100k on their car, especially if it is modded. Are these engines reliable over 100k?

There's a guy on a iwsti that's stage 2 and has 180,000 miles. He says it still pulls strong.

I have seen many modded Subi's with 100K plus. The key to any vehicle having a long life is keeping up with the maintenace.

You need two things:

1) proper maintenance

and

2) a good tune.

07+ EJ257 (STI) motors don't put up with much more than 350 whp for long.. 06 and down is usually good to about 450 w/ a good tune. As for the 06-07 EJ255... I've heard people making 350-400 with em... dunno where the edge of that envelope lies exactly tho

I really, absolutely, find find it quite hard to believe a stock engine EJ255 with stock casting pistons, holding 350+whp for more than 60,000 Km without blowing a piston or two........I know I blew two engines with stock pistons, first @ 50,000 Km and the second @ 8000 Km. I am currently running 296whp with my third engine, the diff is that this one has Cosworth pistons.
Have Ecutek tuned and and an aqua mist water methanol system.
So far 12,000 km, oil consumption is around 0.5 kilo per 4000 Km.
I know at least another two cars, one is a 08 sti, blew pistons @ 8000 Km and the other is a 09 sti, blown pistons @ roughly 2000 km , both engines were stock.

Every car you mod will heavily depend on your tune. If you are talking about a TBE and a tune then your car should easily see 100k + as long as you keep up with the maintenance and don't push the limits of the car. Do some blow up before 100k...yes. However, you'll hear stories about that happening with each and every car. Treat it like you'd treat Jess Beil on a first date and your Suby will last.

I guess this is more typical for the 2.0 liter engines.

I blew up my STI motor in an OEM un modified STI at 30k miles from the horrible oil pick up break. Luckily under warranty, just shows that nothing is indestructable.

I have a 2005 Sti and it has almost 120K on it thanks to a long assed commute to work. I haven't been easy on it by any means and I suck at maintenance. I change the oil every four thousand miles and I changed the spark plugs at around 100K. I drive it like I stole it and it has never broke down once. The only mods that I have is a 3" catless exhaust because my exhaust was so rotted from the new england weather that the cat disintegrated. I never even had it tuned. The car is a goddamn tank, and the only thing that I would have to complain about are the crappy struts (or the crap that they use to lube them) and the rear stabilizer linkage. I'm working on a new powerplant and I'm going to drive this one until the stock drivetrain turns to dust.

My old EJ205 I turned in with 99,000 miles on it. Ran a Big 16G @ 20psi for about 3 quarters of that with no problems. Then on the other hand I spun a rod bearing in my STi at 35,000 miles. I drove them each just as hard and maintained them just as frequently. Sometimes it will just come down to luck when going for high mileage on a modded car.
