It's really that simple ... if you are scared to death of a ringland failure, then do not mod your car, and your chances of experiencing it (or other issues) are much smaller.

As for your warranty, in all likelihood SOA would not cover a ringland failure due to the aftermarket downpipe and tune. The reason is not because SOA hates mods, it is because at stage 2 your car is way outside the stock parameters. However, some dealers are more willing to help you out than others even if SOA denies a claim.

All that said, do not even try "going back to stock" if you have an issue. Your not fooling anyone because it does not take a rocket scientist to see your downpipe bolts have been removed .. and they WILL look. If your going to mod, then own it, because if it blows it is not Subaru's fault ... it's yours.

If you have a ringland issue, you will know it. The car will run like complete crap, and use oil like crazy. The way to be sure is to do a compression check .. but if your running like crap, going through oil like mad, and puffing smoke out of the oil filler cap you can be sure they are toast.
The thing that bugs me is if I cant tune it I would at least be happy with a rock solid tune that doesn't detonate. Why produce a "tuner" car with a ****ty stock tune? I haven't seen the logs personally but Ive seen the graphs showing lean spool. On top of that Im getting blue balls under WOT cause this car is just a tease of what it should be it falls on its face up top.

Im hearing Stock or not your in the danger zone and that's really disheartening. Denying claims based of tunes is only a scapegoat for SOA to escape some of the claims.

I should be able to put intake and exhaust without worrying about the bottem end going and blame being placed on me. I'll keep this thing until the 3/36 is done and trade it in. There is no way Ill survive 100k without modding so Im going to get my extended warranty refunded.

It's all about emissions man. The EJ motors are old, and get poor fuel economy, so Subaru has gained some MPG in the tune.

I just do what I want and don't worry about the warranty. But if you really want to maintain your warranty, I can understand how you feel.

You have to worry about warranty when the car will go through a short block even stock. I knew the EJ motors were not as stout as the 4g63 when I choose this car over the evo. What I didn't know was that I would have to give up any and all mods because the car is a ticking time bomb stock and that blame will be passed onto the owner for any minimal modification. You don't have to worry about giving up your warranty on other platforms because the bottom end failures are uncommon with minimal modifications. I dont mind dropping in a forged bottom end in order to go big turbo but to have to so for minimal mods is just insane. Man I wish the evox wasnt so ugly.

You're spending too much time on this site if you honestly believe your motor is a ticking timebomb in stock form or going with simple mods like a CBE or Stage I tune. Yeah, you might possibly run into an issue with Stage II mods, but keep in mind that setup is pushing 20 to 30% more power (hp or tq) than stock. That's a pretty significant increase and not many motors, especially turbo ones, don't do especially well when you push the motor that much harder.

I have yet to read about a stock or Stage I 10+ WRX loosing a ringland.

Exactly this ....

2badbeast, you are way over thinking/worrying about this. Besides, if you bought to mod, warranty should not be any concern of yours at all.

They didn't build this car for us, they keep building this car to comply with homologation rules. For their race teams.... which they keep firing

so basically, stage 2 is the beyond the point of saving it via warranty.
Now that is understood, another option now would be to switch out to forged pistons with a pro tune, but i'm new to this also. Forged pistons vary in many different sizes, whats the difference with each? Will boring the wall to fit the pistons affect the longevity, reliability, power of my sti? Do i need supplementary mods to go along with the pistons?

If your just going stage 2, I would not worry about it unless you break something. Seriously man, the issue is extremely overblown. I've owned 3 WRX's over the past 8 years or so ... All except my current car were stage 2, and it will be this Spring. I have never blown a ringland.

Am I just lucky? Maybe. But if this issue was as common as some around here make it out to be then I find it hard to believe I dodged it this long. As long as you use quality parts, a good tune, and don't beat your car all the time you will likely have no issues.

Parts failing as you add power mods is always a risk, and no one can guarantee you won't break something ... but you will find many people on this forum with tens of thousands of stage 2 miles on their cars with no major problems at all .. including myself.

But will you find someone with an 08+ who hit 100k miles on the same engine that verified with compression test/leak down etc...that they didn't blow a piston?

Doubt it. A good friend of mine bought an 08 STI and his block popped at like 36k. Very sad

That's my point. You probably won't find one because there's a very real problem that some people refuse to acknowledge.

I'm pretty sure this issue was only directed at stock WRX's within the build dates, not the STi.

Once you start modding *anything at all* you are falling outside of the scope of the issue.

I'm stock (factory SPT axleback) with a build date of 04/09 at 65K+ miles. I've had 2 UOA's which both state wear is perfectly fine and the motor is healthy. My FLKC table also sits at 0's across the board.

LOL ... why on Earth would someone with no engine symptoms do a compression/leakdown? If you blow a piston, you will notice something is up which will lead you to doing those tests ... if your car is running good with no issues, why would you even think of doing this aside from sheer paranoia?

Anyways, I'm done debating this with you guys. If you want to believe that massive amounts of stock Subaru engines are blowing up randomly all over the planet, and there is some great conspiracy to ignore it, then have fun with that.

I did a leak down for a baseline reading so I can better diagnose any problems I May have.

Lol I agree with you on that I'm on here too much. I do a lot of searching on mods before I spend my cash and try to avoid causing any extra costs. I suppose I dont have to go stage 2 but that sounds ideal. Man the mod bug is something else.

I'm not supposed to be modding this one lol. I have 2 other projects going on but it's hard I didn't think I'd like the car this much. I just want a little more boost better tmic downpipe tune and some monitoring equipment. Nothin big

Because you can crack a piston/ring land without even realizing it, i.e. w/o obvious symptoms. Since these engines are prone for it due to inherent design flaws...it's never a bad idea to do this as an owner or as a prospective owner of a preowned WRX/STI.

Depends on the sri.

Also, sri's are stupid and make the car lose power due to the change in timing and AFR caused by the ECU reading such a high IAT. Either get a cai, or stay with the stock intake if you're running the stock draw through MAF.

That's interesting, (not being argumental) where did you get that info I am starting to make plans for a build and want some real substantial gains. I've never read anything concrete about increased iat on an Sri while the car is in motion...obviously at idle it makes sense. But in motion, again I've heard arguments on either side but not any real documentation.

Thanks

Have anybody with a sri take a log for you, this is WELL known and WELL documented. IATs while driving are easily 50 deg higher than ambient with an unshielded short ram, which will have a significant effect on the ECU's fueling and timing compensations. IIRC my IATs while driving were typically over 150 F with a sri, in ~90 F weather. On the freeway it would drop a bit, but still well over 30 F above ambient.

You will never get substantial gains from any intake on our cars, they just don't make power unless you're already over 350 whp. There are MUCH better places to spend your money than an intake (especially a short ram) if you're after power.

I'll do another search for better documented numbers. One of the things I've learned from being on Nasioc is that the more well known something is...usually the less factual it is as well. This is a community of elitests. Hence, asking for real numbers.

Just for the sake of confusion. I wasn't looking for a gain from an intake; however, looking at an intake is a component of a build. Also to mention that a peak whp wasn't as important as a long flat power band...

Thanks for your insight.
