BOOM-'FREAKIN-BOOM That's right, another one bites the dust... I've been going through some of the blown engine threads so here's the details you wanna know: 2007 speed3 Speed: cruising @ 74MPH RPM: close to 3k Boost: somewhere between -15 and -20 inHg Throttle: partial, less than 20% Coolant temp: 187 Boosted temp: 110 EGT: 1300ish (my sensor is before the turbo) Feelings: panic, denial, pissed and finally worried thinking how much this is going to cost Rundown: I was driving back from MAZDAFEST and had been driving for close to 3 hours. About 15 miles away from Columbus on my way to Cleveland i heard a pop, clank clank and the engine stalled. Looked down and saw the oil light was on. Say smoke coming from the hood and tons of smoke in the rear view mirror. Pulled over and saw a trail of oil and some more on the bottom front of the engine. Thankfully the flatbed got there in 30 min. Mods (oh boy): COBB inlet, CP-E SRI, CP-E FMIC, CP-E HPFP, CP-E turboback w/high flow cat, SB and PNP set to 16PSI, TurboSmart BOV set 50/50, 2 step colder plugs, PNP mani with EWG w/0.9 BAR spring, PERRIN E.B.C.S. Background: it takes me 2 weeks to tune my SB, I do it as described by Haltech on another thread (let it settle after mods are done and go WOT little by little). NO KNOCK @ WOT, my AFR curve was steady @ 11.8 all the way to redline. I take logs every 2 weeks to make sure nothing has changed. I have been getting the part throttle knock when cruising for a while but as it has been stated many times it's not relevant (or is it...). I ran 18PSI for a while but went back to 16 just to be safe. I didn't see any of the part throttle knock on my way down to Indy nor on the way back. I don't know exactly what broke or bent, will find out sometime this week since I had to leave the car at a dealer I don't know 2+ hours away. I'll see what my dealer says about bringing it here, not very optimistic about having them fixing it but they know about the mods and I have an extended warranty with them so we'll see. I'll update as I know more. |
ya its weird i drove 6.5hrs non stop (aside from getting gas) never saw the car knock once. At times i do see partial throttle knock around 3k rpm... This car is fucked up sometimes... Sorry to hear bout your loss though. Let us know what you come up with, and if you decide to build it or what your plans are. |
Wow, all the treads recently about blown engines makes me not want to mod my MS6 at all!! If I do anything, I might just throw on a SRI and call it a day! Damn... what's wrong with these motors?!? BTW, sorry to hear about your car. |
fcuk me ... another one? This car just seems to be plagued with so many gremlins. |
I think when my times comes it will be the same way. |
sorry to hear man, keep us posted |

lol this is definitely a hard car to have fun with, with all the horror stories its just not worth moddin this thing |
arrgh ... I dont' know what to do now :( I was so excited to mod this thing. I have an AP on it's way (bought used), cpe mm, and su test pipe coming already... I have a cobb sri, forge bpv and twm ss on the car already. And am JUST about to order the Cobb FMIC. But it seems like there is NO safe amount of mods on the car, and it just seem so RANDOM as to when and what the engine will take. I'd like to THINK that with intake, bpv, fmic, mid pipe mods i'd be safe ... but maybe not and then the ap in there with a tune is SUPPOSED to make it safer but thats a maybe not now too. ARRRRGH |
Yikes... Sorry to hear. I was so paranoid for a while but if its going to go you can not do anything about it. All you can do is try to take all the precautions and hope they work. BSD this week w/ the Oil filter conversion and internals. |
Quote:
And while BSD may or may not stop this anomally from happening, it's not proven yet and theres a part that would be tough to return to stock should anything happen. |
Good luck! |
i hate seeing these, sorry for the loss. |
sorry to here man....this makes me want to throw in the towel again motherfucking mazda....i wish we could start a class action law suit, but it seems that all the friggin cars that are popping are not stock, so we can't do it... how many miles on your car??? i feel like getting rid of mine this week cocksuckers, this is PISSING the shit out of me!!!!!!!!!!!!!!!!!! |
so no bsd? |
It seems to me like many of the fully bolted cars are blowing. I am not seeing a lot of blown light bolt on cars, intake, rp, maybe a fmic and so on blowing up. people have blown with all sorts of mods, but it just seems like full bolt ons with this car is really taking a chance no matter what you do. It seems to me that its the bolted guys, the big turbo guys, and the occasional odd/random blow up from the guys with very low mileage. Why dont some of our other fully bolted/BT cars blow with meth? I doubt meth is some magical mod that allows these guys to beat the shit out of their car daily with no issues. |
it literally happened a couple of miles after 33.000, this car has pissed me off many times... I almost traded it in once but the numbers weren't good enough. The only way I would keep it is if I get a forged engine from PG or SU but it's expensive and I don't know if it's worth it. Going back to stock is another option but it would have an engine from the dealer and I have several doubts about that. I have to talk to the dealer to see what happened and what are my options but at this point I'm more than willing to take a loss and get another car that will give me more peace of mind |
no BSD? im not surprised |
Sorry to hear this...Did you have the vibrating clutch before it blew? Im just hoping my engine makes it another 2 months or so because Im ordering a forged motor swap from P3 next week and should have it all done sometime in June...I hope I will be able to enjoy this car after that instead of waiting for it to blow all the time. |
In before the BSD posts!...ah god damn it. |

But for everyone that gives up on these cars and moves on is completely understandable. |
While its definitely odd for the car to blow while just cruising on the highway under zero boost....its not like every other fucking car is blowing up. Its an incredibly small percentage...an unacceptable small percentage I totally agree. But its not like you need to be driving around "waiting for it to blow". |

Does it vibrate when its in, or out, or....what do you mean? |
Your clutch pedal pulsating at idle moreso than your brake or gas pedal. I am willing to bet that there was stupid STUPID EGT going on. Think about it, our cars lean spool (pulling asston of timing to generate EGT to spool turbo) Coupled with the stress of a balance shaft, fuel dilution of oil, and increased airflow from boltons can very well = boom boom. Did you check your oil level before you left? Jeff at PG |
As many hypotheses as there are, I think most people will agree that a lot of these failures are probably due to some flaw with the motor. Some are lucky some are not. Some people beat the shit out of their cars and all is well. Then some lose them cruising. So you can either sell the car or just drive it like it was meant to be driven and hope you're one of the lucky ones. |
Well the shitty thing is that even if we end up one of the unlucky ones, mazda is gonna blame it on mods to get off scott free. And theyll smile big when they get to order a new engine and take their sweet ass time getting paid $120/hr putting it all back together. All coming out of you wallet, but is it really your fault because you had some simple bolt ons? So theres absolutely no way to save your ass other than to go bone stock and stay there....all so that you can be safe if...IF your shit blows up. And what fun is that? It pisses me off that mazda is never held accountable for this and theres no sign of any kind of investigation into why this is happening. If its the balance shaft, then they need to FIX it. Its still a very small percentage of engines blowing, but when I hear of cases like this (cruising down the fucking highway under no boost) it scares the shit out of you. It can literally happen to anyone. |
Just demod the car if it blows before taking it in ... but that can also end up being abused. |
Quote:
Just because a mustang/evo/supra/skyline/whatever can make "X"HP on a stock block without blowing doesn't mean that Mazda pays when theirs doesn't. If you mod be prepared to pay. I have to hand it to the OP. He didn't blame Mazda for the engine blowing. It sucks when your engine blows. I feel for you. Best of luck with whatever you plan on doing. |
That is exactly my point, you cant mod at all because if your engine pops you're fucked. I'd be willing to bet money that its a flaw in the engine, no way are basic bolt ons causing blown engines at cruising speeds on the highway under zero boost. No way in hell...its an engine flaw. Mazda should pay, its their flaw, but if theres mods, they wont. |

BUt there have been stock or very near stock ms3s and ms6s blowing up under similar circumstances in the past. What blows my mind (no pun intended) is that this happened at -15 to -20 vacuum, thats practically coasting. I just cant see how bolt ons could contribute, thats like saying my car sitting in the driveway idling with no one behind the wheel could throw a rod. |

Sorry to hear that man! a buddy of mine just blew up a couple weeks ago too. all he had was a cobb intake and inlet and AP flash! |
This worries me... Unfortunetly, this seems to be happening a lot lately. Hopefully somebody can figure this out. If my engine does blow, i am sure in hell NOT buying a 2010 because they look like shit... Did you notice anything odd about driving around before it happened? Shooooooot man sorry about it. |
Yeah, as someone mentioned, at zero boost like that cruising, the rod/s must have already been bent to some degree, and just decided that it was a good time to blow a hole through your block. One sever ping or instance of pinging could have caused a slight flaw to appear in the rod, and then its just a grenade with the pin pulled. And I am sorry for the loss and inconvenience, hopefully everything goes smoothly from here on out! |
i check the oil every two weeks and before long trips, it was full before i left car didn't feel different or strange being towed back to cleveland right now, was told by several people the dealer it's at is awful. Was given the option to trade it in so I'm thinking about that and minimize what I have to spend/lose. |
what did they say they would give you on trade in? lol I would grab all your parts off the car btw! |
no numbers yet, just the option. If I go that way most of the parts come off so I'll have different parts in my FS thread |
guaranteed this cars damage was done prior to him popping. No way in hell it would pop from just cruising on the highway. quote Phantom3 What exactly should Mazda be held accountable for?? There is no proof (as of yet) regarding a flaw in the engine. The car comes with a warranty under the premise that it will stay stock. If you are stock and you blow then it is covered. If you mod your car then it's your own damn fault. Why should Mazda pay for your fuck up? Mazda engineers don't sit around and design an engine with increasing the HP with aftermarket parts in mind. In fact it wouldn't surprise my if the engine was designed to pop on purpose... I"m just saying You no i bet Mazda enigineers do no why some of these engines are popping and i bet it is not JUST from the BSD. and honestly Phantom theory is not so far out i bet the Mazda engineers took this car to the grenading point and probably have popped a few to see where the popping point is... and i bet its not to far off stock levels...Mazda clearly knows how much this engine/ecu can take before a failure happens,,,and indeed when a engine pops that has mods...Mazda is off the hook...and at this point they probably are happy when a cars has mods so they not held accountable..IMO it is a combination of all the mods putting the engine in stress because it was not designed to handle extra boost/power as well as the ECU not being able to compensate for the changes that the mods have created, especially when boost is increased..We no the car can handle a CAI and CBE as Mazda has them from the factory.....and i would bet a TBE may put this thing at its line for safe power upgrades...any more than that especially with boost over stock and it's only a matter of time..without meth... Not trying to be negative about folks buying mods as many vendors make a living selling them, but this friggin platform can't handle more than a few light bolt-ons and stock boost. My recc is drive in balance, shift by 5500 tops, keep the boost at stock levels and do not over mod this thing...TILL it's built for more power first...otherwise stay close to stock levels. I am...and so far no issues.....I like my car and as much as this shit pisses me off i am keeping it and driving it a we bit more aggressive than normal....but not by much LOL |
drive the hell out of it. Runs better that way. |
driving the hell out of it with too many mods is why this thing is popping...the damage is done when driving the hell out of it and it pops when you would never figure...it like Phantom right Phantom? |
i often drive the hell out of my car and its just fine so yeah its hit or miss. |
Quote:
Id like to see a fund put in place to get one of these popped engines in the right hands to find out REALLY what is going on. Personally I'm leaning towards crank walk / thrust bearing problems. A heavy duty aftermarket thrust bearing would be nice. Or a forged aftermarket crank. :fing02: |

quote smakdown..Since no one really knows whats causing the failures, it could have absolutely nothing to do with mods. We don't know yet until someone does a complete teardown. True...but 99% of the cars popping are moded and the more mods on our car generally have a higher failure rate...maybe coincidance but something is creating this "overload" somewhere that is grenading these engines that have mods. True, there have been a handful of stockers with issues...but if it was a defect there would be more stockers blowing....it is a chance that the "defect" what that may be is failing faster because the car with mods are making more boost or power and stressing the "defective" part or parts....but facts are facts ATM and the stockers of lighly bolted cars are have way less issues...so a mod or a combinations of mods is putting this car into a failure position or making the questioable defect react with a failure much sooner than if the car was stock......Mazda knows what is happening and they no when this engine will fail and why...they are just not sharing the info....they may want moded cars to fail....but IMO this is a un-wise business decision....honesty alway's prevails. but they must feel that if kept stock the failure rate is very low so they will not open up.....now if stockers were popping that would be a different story. Or as Phantom mentioned, maybe they did put a grmlin in the ECU !!!!!!!!! |
99% of the cars WE SEE on here are modded or they wouldn't be here. |
damn gremlin. i should install my cat into the ECU. she eats rabbits, mice, birds, and other shit too. maybe she could show that little bastard what's up. BUT srsly, IMHO the engine should be stout. it's got rods comparable to those in an Evo X yet those same rods are snapping at much less power than the Evo's are capable of. as far as 'good business' goes, if Mazda has minimal issues with the stock cars, and the owners of stock cars love the MS3/6, then why give up the secret of why modded cars blow? although if they did give up the secret and these cars were laying down 400whp easily, they'd prolly sell a TON more of them.. one thought - let's say Mazda knows what the problem is. what are the odds that they've 'fixed' it for the 2010 MS3? other thought - any smart Mechanical Engineers around here? we need to place a spy inside Mazda corporate! |
How do you know 99% of the cars popping are modded? how do we know how many people blow this engine and AREN'T on the forums to tell us about it... and aren't modded. |
indeed i am not positive that 99% of fialures worlwide have mods....but i was the 1st Speed3 that was bought at my dealer in Nov,06 and i have been active on 2 forums and frequent 2 other just to keep up on whats going on. Stock or moded, if you are a enthusiast wanting to improve your platform chances are you are going to be involved in one of the forum...and if my engine popped and i was stock or moded holy hell would break loose on a form...but i have only heard of 2 stockers popping, thats why i said a handfull....but 99% of the time they are moded and have been driven very hard frquently....now very hard to me is fine and safe if driven in the sweet spot of this car...but going WOT on every drive day in and day out with boost set at 18 or better...taking it past 6000 rpm on a all to often basis IMO will hurt this car especially if the mods have you near or over 300whp....driving correctly and shifting at 5500 and not beating the living shit out of it ALL the time will benefit this platform for longevity stock or moded... |
I wouldn't have a problem sending you the parts, IF (that's a big if) mazda pays for it then I'm sure they'll keep em but otherwise you can have them |
I still think were looking at a small percentage of cars that are blowing compared to the number that are modded, look at how many high hp/tq cars have stayed together with meth, i really think a lot of the blown motors are detonation caused. |

its not power or mod related. I'm not a lucky guy and im still around unblown up for now. I've boosted and beat on this car 7 ways from sunday. I have meth and I still have my BSD. The way dudes are blowing up im sure its a design flaw not a power related issue. |
^I'm with you on that one. If it was power related, guys wouldn't blow cruising on the highway. It just doesn't make sense. BTW, how many miles are on your car? |
Someone said mazda has a new part # for there thrust bearings so that may be part of our problem.. |
33.000 miles |
If it was a flaw, it seems pretty damn unlikely that it would take 33k miles before failing. |

But no body does that. All everyone likes to do is GUESS... and that hasn't helped ONE BIT ever since the introduction of this car. Every single case of incident (fatal, or just a minor one) in the aviation industry gets investigated to find the EXACT reason for why it happened, and most of the time they do find out the exact leading cause, or multiple causes of an accident. This can be a 30 second investigation, or a year long investigation, but the cause is almost always found. This is a car people... not only that, its the engine in the car. I'm sure there is enough money in this community to investigate such a common problem with it. Funky |
Quote:
And I agree that the cause needs to be found or at least investigated. This scenario is a classic case of a "what the fuck?" engine failure. OP if you can get that engine into competent hands to see what went wrong, please do so...you'd be doing the community a huge favor. However, if financial reasons prevent it (having to trade the car in, mazda keeping it) then its understood. But I can tell you right now if Mazda covers this under warranty then theyll be taking that engine and doing their own investigation, and then keeping a lid on it and the info will never get back to us. Also, I highly doubt mazda is intentionally popping our engines using planted gremlins. With companys like Cobb out there digging through ECUs they run a huge risk of being found out....then what? I highly doubt it. |
bummer.. sorry to hear it... thanks for all your info my friend. keep us posted!!!! |
So, there's never been a proper examination of a grenaded motor, by any other than Mazda? I thought I read DCR had some blown motors they were looking at? And somebody send one to Forzda! |

If it was tune related I would be blown up LONG time ago cause I've been on stock ECU this entire time. boosted 30+ psi blew turbo and injector seals but still here Boosted 27psi on the dyno 3 times still here raced the car on 19-24 psi for over 9 months still here Threw a 60-1 on the car cranked it up to 27 psi made no big power BUT still here....... Trust me its not power or abuse related cause my motor would be the first one called home to mazda heaven if that was the case. That's why there's no sense fearing the thrown rod gremlins cause its all a gamble. Enjoy your car mod it how you want to and drive it how you want to. When your time comes it will come. If you don't want it to come leave the car stock, stock the car out, or trade it in. |

I think I've now made that decission too ... I'm going to still try to find an ETS TMIC, and call it quits at that ... If I have to take the car in for anything, the SRI and TMIC, BPV, Testpipe will swap out in about 40 min, and it still should be fun. Realistically there are more important things to spend the money on. Maybe in a few years when my cars paid off and someones determined WHAT makes this car go boom, I'll start it up again and make it a project car, but this is my DD so I really shouldn't be messing with it too much. |
Quote:
|
I hate to say this...but this is why I'm only doing the SRI and BPV...I'm just too afraid to pop this thing. It's sad as 4cyl cars can be fun to play with, just not this one I guess. |

Ding ding ding, we have a winner! How many cars with meth have blown? One, afaik, and the damage was probably done before the meth. I still don't think it's the random flaw theory. Also, not to start a food fight here, but look at how many are Standback users, and how many are stock ECU or AP. Just add up the numbers. So I was bored & decided to do the math. Stock/MBC: 15 (1 3 5 6 7 8 9 10 12 18 19 20 22 27 28) Standback: 4 (2 11 15 23) AP: 3 (14 21 29) The Stock/MBC is weighted pretty high because I assumed Stock/MBC if no other tuning was mentioned. Also, I am sure the AP numbers will jump with the release of ATR. |
How easy is it to go back to stock from meth injection? :P |
There is too much speculation, there is NOT one reason or solution (meth) in order for the engine to blow or not to blow. There are too many scenarios, there was even a ms6 with 78k miles highly modded who blown an engine a couple of weeks ago. and to the guys that wants to pitch in the money to pinpoint the problem, you're getting over your head, first, money...lots of money, then finding the right people, then giving them the right info, parts ..ie the blown engine and the vehicle that the engine is in...they have to diagnose every part ie bov, intake, exhaust, fuel pump, etc etc..you get the point. Its not cheap, they get paid by the hour, much more than a measly mech.. basically its just a pain to solve this, Mazda has the answer and they are not telling. I don't believe that this engine blown that easy, most that blown are under 300hp, some barely made 300. I believe there is some faulty engine and with a combination of mod added increase the chance of blown engine. That is the only reason I haven't got any ecu management system. The ETS TMIC is my last mod, I was thinking about getting a downpipe down the road, but I'll have to wait a little longer. I have over 53k miles now, I have cobb sri,inlet,swaybar,tmic, both pmm and tmm not install, also not install occ. have cs inserts but order cpe rmm on the way. The car is running great, better than new with sec set of tires yoko advan, definitely will get the ms coilover later. okay now that you know what I have, lol here is a funny question, what's the chance of my engine will go. one thing for sure if it does....I'll cry about it sniff'sniff..and won't post about it..j/k |
It's not speculation. If you pay attention you will see a pattern. It's not a Mazda conspiracy, either. http://zapatopi.net/afdb/afdbsmiley.gif |

then what is the pattern? are you saying METH is the savior? after only ~100 guys running meth, you're prepared to say that? amazing Kevin needs to add some more challenging questions to complete the registration process instead of the just "type the capital letters".... |
