Why is this turning into an Evo vs. WRX thread? The Evo's not even in the same price range, and if you think Evo motors don't fail you're just naive. No platform is exempt from failure.
This is supposed to be about FA motor failures. It would be nice to keep this on topic. OMG a motor failed on a stage 1 OTS tune? No way! You are aware that there have been failures of completely stock FA motors right? I've got over 30K on my Cobb OTS stage one WRX and it's still running like a champ, and I'm not easy on it by any means.

Just my 2 cents; 1st case: Ringlands can crack days, weeks without symptoms before failure and then break when pushed hard. IDK about the cat but the ringland could have let go from damage occurring much earlier. Seeing Nevada in your profile leads me to believe at some point you were running 91ACN. These cars hate 91ACN. 2nd case: if the ethanol percentage is not known then you really shouldn't list E85 (although you clarified that). I guess it's just mincing words. I will state the obvious: Ethanol is a two edged sword. It can allow tuning for huge power gains but detonation when it does occur can be catastrophic. I think this is confirming that the actual limits on the stock motors may likely be the connecting rods. Sorry to hear about your losses. |

I know I'm just being a bit picky but I still laugh when people say A LOT of failures. A lot in terms of your opinion or a lot in terms of facts and figures? Because i've still failed to see anything that equates to A LOT when you factor how many WRXs have been sold and how many are running modified parts.

Damm man I'm thinking about canceling my wrx order with all these bad news.i had an 8 gen civic si boosted(386whp) for 4 years stock internals and I have never had a problem with it,a matter of fact I know of many K series motors boosted stock internals and don't be hearing about blown motors but then again there transmission actually suck(strong motor weak transmission
I suppose to get my wrx by the end of October but I'm thinking if I should cancel with all these horror storys The wrx is such a good looking car |

To paraphrase Nixon, there's a silent majority of owners who don't have problems and don't post on the internet about it either way

I don't mean to troll but so many already are, I think these cars may be allergic to dynos. heyooooo, I'll leave now
oh yea, and if EVOs are soooooooo good, why didn't you buy one? |

subscribed.
Also, like people have said already, this is the best selling generation of the WRX so far so there's bound to be failures out there. |

It's kind of true because there's a dude with ets turbo kit pushing 420whp+ stock internals for a while and his FA engine is still holding on strong its probly all about who's tuning the car

Maybe our cars have emission cheating software on them from the factory. Tuners are not accounting for this, and thus blowing them on the dyno. That must be it
EDIT: In all seriousness, every car model has its group of failures: http://www.evolutionm.net/forums/evo...on-thread.html If I see 1% of NASIOC 2015 wrx owners post up about them blowing their stock motors this next year, then I will begin to worry.

Subaru has sold nearly 40k WRXs in the US since it introduced the 2015 WRX. From the data I can find that is the same number of Evo Xs sold in the US since 2008. So even if we have 40 confirmed blown motors in the US (which I wouldn't doubt because not everyone talks about it.) that is still only a 0.1% failure rate.

It does make you wonder though, why did Subaru stick with the EJ on their flagship STi?
If I'm not mistaken, even overseas they still use an EJ20 in the STi. |

I like the satistics, but isn't this thread more of why is it happening and what are weak points of this engine vs don't get your panties in a wad noobs about a motors blowing. If this thing stays on point we might get some good info and be able to map out mod priorities and do's and don'ts of the platform.
Anyway, the main reason I was commenting is... (God forbid I bring it up on this site) no one's mention type of oil being used (not brand just if it's the recommended 5w30 or something different) and the oil change intervals being used at the time of failure (is it the soa recommend or something else). I believe this is also good info to have since it's the blood of the engine. P.S. I hope that me asking doesn't turn this into another oil debate. It would destructive to this whole thread. |

If you guys don't think EVO motors, especially current gen ones, don't blow with relatively modest power numbers, I'd suggest you go spend some time of their forums. Also, the EVOs are wrought with all sorts of expensive and common drivetrain issues. In the end, both of these cars can potentially cost you dearly once you start modding them. Pay to play, fellas. Subaru isn't here to support your personal racing program nor design motors/drivetrains to handle more than stock power levels.

Just for some perspective they have sold over 40K 2015+ WRX/STI vehicles in just the US alone in the last 18 months or so.
I don't know how many are modified by my guess is thousands of those. You are gonna see failures on a new platform as tuners and owners are trying to push the limits and understand the breaking points and best ways to tune. Relatively speaking, the engine is still very new to the tuning scene and people that are pushing the limits are going to pay to play. As for the car that blew up on just a stage 1 Cobb tune, you guys realize there are a lot of factors at play besides the tune, right? I mean you can blow a car on a stock tune too if you have bad gas, low on oil, and push the car too hard. Datalog your car even on Cobb OTS maps, use good oil and check it often if you drive the car hard. When you sell 40K+ cars in about 18 months there are going to be some bad eggs in there too. It is just law of averages. |

I've noticed that most of the blown engines I see here don't have upgraded intercooler.this probly a stupied question .but could it be heat related?

The problem with these types of threads is that you don't always get the facts as most people that blow a motor will not always offer full disclosure. So you just have to take a lot of this stuff with a grain of salt. |

Okay, oil has been added from what I could gather from the other threads on their motors.
I wonder if I should just start gathering data from other sources too. Some data is better than no data, even if people don't fully disclose. |
