Default 08-12 WRX ring land failure?

Hi guys,


Lately I have been curious as to how many guys/girls here have had ringland failures on there 08-12 WRX. I read all over the internet & NASIOC about STI ringland failures but not so much with the WRX.


I ask this because I have a failed ringland and I'm current looking into rebuilding/buying a new shortblock with forged pistons



My car is:
09 WRX
Stage II Cobb tuned w/ SF intake
37,000 miles

Here I thought I was going to be directed to a thread with valuable information. Only to find out it was just a link to the "Warranty Issues & SOA Problems" thread where there isn't a current thread about this going on. Not helpful.

Please do.

That doesn't pertain to ringland failures- only the rod knock/bearing/crank issue that yourself should know about having an '09.

I'm just trying to educate myself on potential issues that may arise so IF anything were to ever happen to my car (stock), I would initially have more information about it at that time rather than trying to figure it out after the fact like the OP.

My 2011 wrx cracked two ring lands at 14k miles on the track cause a hose popped off the intake manifold. I rebuilt the short block and needed some head work. Been about 5k miles on the built motor.

Car was protuned at eqtuning stage 2 at the time

Default Ringland failure

Get a open source tune would be my first step.

i would like to know more too, i hear that there are lean A/F spots in a certain rpm range due to emission control that may cause ringland failure...im getting a 2012 wrx soon

Would high attitude cause STi engine to run lean? And cause ringland failure eventually

In Colorado we can only get 91 octane

Many things can lead to ringland failure. If the car is running lean would be based on the tune. Do you KNOW your car is running lean or is it just a wild guess?

91 Octane is fine to run in any car. From the factory these cars are required to run 91 OR higher whenever possible. You can also run 87/89 when 91 is not available.

I was just curious , because I just ordered a 2013 STi .

Where I live in Colorado , I can only get 91 octane . So that should be ok.

Is there a reason why Colorado does not offer higher octane ?

That would be something far above what most people on this forum would know.

Edit: I say since you don't have the car yet, don't read too far into any issues. If you drive the car normally, and even lightly modify it you should be fine. Is there that chance? Yes of course. But there's also a chance nothing could go wrong the entire time you own the car.

i was curious about this too. totally depends on what you do with your car.

may it be your just a conventional driver or a I JUST WANT TO GO FASTURRRR

if it happens it happens, so if you have warranty have them fix it. if not there are plenty of threads of people who are fixing their ringlands and misfires (Search Option)

you'll find out sooner or later what the 2013's have to deal with, so will I

Ya it's very interesting , I really want to get a intake for it and tune it with the Cobb access port, but don't want to void warranty ...

So I will probably just leave it stock. This is the main reason why I wanted to buy the STi vs the WRX . More power, upgraded parts, better platform and overall a better car with warranty .

I'm really glad I made the decision to go with the STi . Congrats to you on getting a 2013 STi also!!! Soooo excited !

FYI the intake will do very little for the car, and once you tune it with an AP you run the risk of warranty denial. Hell, even if you keep it 100% stock there have been instances where the Warranty claim is denied.

I don't expect any change for the 2013 models with the "issue." And even so, it's been an "issue" since long before the 08's. My 06 blew with 98K miles.

Dealer always look for sign of abuse when bringing in for warranty work (powertrain, brakes), Subaru should made these car more robust.
We don't buy WRX or STi to drive like grandma or keep everything stock, the fun of buying these cars are when you can drive at WOT and working/upgrading your car.

Ya, I'm just going to keep it stock and be happy that I have a STi and hope that if anything goes , it will be covered .

It's crazy Subaru has not fixed the problem . But it's a small percentage .

I'm very easy on and maintain my cars.

Here is a good article about the EJ- series motors by Import tuner

Meh.. I cracked the piston in cylinder 2 last about a year ago on my 2008 WRX. Went stage 2 at 53,000 miles, and did a 20g swap at 70,000 miles. Piston gave out at 73,000 miles. I'm not surprised...I was having overboost issues during tuning the new setup and consistently hit 25psi over a period of a month on 90 octane (that's all we have in Alaska). And in that situation I know it was me (25psi+90octane=Heat=Detonation=Cracked Piston=My fault) that caused it so I didn't even bother with Subaru.



If you choose to go down the mod path - be prepared to pay to play. It's not a question of if, it's a question of when. Some people tend to have a better track record than others.. for example my ex-roomie is going on his 3rd motor in 30,000 miles (first two were rod bearing failure, latest is suspected ring land). You'll find tons of different people that have experienced failures at different times, under different conditions.

My advice? Pull the motor, and rebuild it to be able to handle MORE than what you want to throw at it.

no your wrong. there are a lot of people with stock who has had this problem.

a lot of people suggested flashing before even leaving the lot.

others also recommend forged pistons.

so i saved you from other peoples remarks.

STOCK TUNES SUCK, If your car breaks down and it still has warranty have subaru fix it!
