blowing your motor questions

[ptruong31]

hello everyone, i might purchase a used mazdaspeed3 tomorrow but my dad doesnt want me to get it because his friends mentioned the blown motor problems. its a 2007 and mileage are incredibly low, about 18k. well my question is, does your motor only blow if you have a bunch of mods? i read on some other thread that it only happens when you modd your car over 300 whp. what if the car is stock except for a mazdaspeed cai? also, when i add mods in the future will a rear motor mount reallly help keep my motor from blowing? hope i dont get flamed for not using search button but i gotta get to work soon lol sorry guys but any answers will be appreciated. thanks.

[CWPspeed3]

well unless your dads friend has one i would tell him not to give advice based on something he "heard". also the search function on this site is pretty good you will find many topics about this but a quick summary.

blowing the motor seems to be mostly the highly modded engines pushing big numbers that the stock internals dont handle too well. the issue with this car is the pcv system and blowing your turbo seals causing smoking. mazda is working on a fix for this. there quite a few ms3's on this site that have pretty high miles on them for a car thats only been out a couple years.

rear motor mount is very helpful and was my first mod, it wont keep the engine from blowing but it will keep the 07 oem mount from breaking and your motor falling out (this issue was fixed for 08-09) but it really improves the way the car drives and i'd replace it regardless.

[ptruong31]

oh alright you been helpful, thanks!

[StealthWyvern]

From what I understand the MS3 all pop their motors due to ton of mods and no tune... Even the MSP is fine if you dont do crazy on mods and they are known for weak motors.

[dizzin9]

if you're satisfied with lil mods, go ahead. if not, find a car that has a lot more potential.

[coyfish]

Yep depends on what you want to do with the car. You can easily get a "safe" 300 whp which is pretty fast especially in a speed 3. If your staying stock or relatively stock than a blown motor is nothing to be worried about. As others have mentioned if you want a track beast then look at different cars.

[Target:STi]

there have been cars blowing up stock and with minimal mods. its rolling the dice really.

Same with the MSP but the majority of the people poping the engines are people with tons of mods for the MSP, MS3, and MS6

In a market of tens of thousands of cars, some WILL be faulty. That goes for all manufacturers. The internet tends to heighten fear and paranoia since those with trouble post their pain widely. This car is very solid. No major recalls, multiple years at the top of sales charts. Crap doesn't take long to smell and this car has a good rep.

is it your mission to bring up the msp in every ms3 thread you post in? just seems like it from where i am sitting. you should trade your msp and get one. these cars are so much more fun to drive than the msp! you will love it!

to the OP
its a fun car stock or modded!

Yep, I'm just comparing it to how its prone to blowing like the ms3. I would get one if you made the payments for me. I can't aford one on a 3-4 year loan comfortably, so I wont get one. Sure I can get a much nicer car like some other people who thinks its good to get the car they want on a 7 year loan... either way its not for me.

[SeR_Cyclops]

Also if you go WOT at every straight road then your motor will not hold up either. Just remember that if you treat your car good then it will do the same back.

(first)Good point, The people with a ton of mods are more then likely beat on their car more often then those who dont have so many.

[cpolly69]

usually folks who mod their cars and run them hard post on forums - so if you are depending on forums for info you are prob. more likely to see blown up engine stories

[funksilver07]

Have them read some reviews, maybe you can change their minds...

(first)Good point, The people with a ton of mods are more then likely beat on their car more often then those who dont have so many. I drive my car hard often. That is what i bought it for. i store it in winter and have over 43 thousand miles on it and ready for my third set of tires. I do not have a ton of mods. I am trying to lighten the thing up alittle!

[Target:STi]

Trolling FTL.

yea what the fuck is that supposed to mean?

it is the truth. motors pop stock, i/cbe, i/tbe, i/tbe/mani/meth/bsd/etc etc. tuned, untuned, there is no common denominator. the best thing to do is leave it stock and hope the dealer covers your ass if/when it pops. otherwise youre rolling the dice.

do the forums blow up the hype of these motors popping? maybe, but i dont think so. in my city alone i have seen 2 out of maybe 6-8 MS6's pop. how many SRT4's do you see popping after putting on comparable mods? Evo's? STi's? not many, at least no where near as many as us. and they have a ton more of those cars on the road and a ton more people on their forums than we do. the new WRX was having some issues but they seem to have it figured out (within a couple months)

i will correct myself, there is a common denomitator. its the 2.3 DISI MZR engine.

[ericrapp]

incorrectly tuned when mods are in place is the issue. Map clamps, boost clamps and such were the early culprits. People turning up boost without monitoring afrs etc. All motors have weak spots too. and as time goes on and people break stuff we find the weak points. Tuning a car takes a good look at all the data and corrects the weak points. sometimes if more power is desired, mechanical upgrades are required also. i think the motor in general is fine. I have no warped heads, overheating, oil smoke. the clutch plate is not warped and still grabs well. I still have alot to learn about this car and am getting some good help from folks here. but to say these are prone to throw rods and melt pistons is just not true. I would appreciate if you would not talk out your behind sir.

[Target:STi]

you yourself said you are a noob when it comes to these cars, so let me help you out. the current record holders for the most power out of both speed3 and speed6 were untuned and simply using a map clamp/bcd and a manual boost controller. i would venture to say that more people have popped using some form of ecu tuning than untuned.

if these engines are not prone to failure, then why are there "blown engine resource threads" more than a few pages long. maybe not on this forum but on others. if these engines were so stout, then why havent more companies hopped on board making parts? 3 years after the engine's inception, we have one proven race team starting to take a good look at us, DCR. if these engines were not prone to destruction, why would we even be having this conversation?

do the math. take the number of blown DISI MZR motors + the amount of recalls issued for factory defficiencies + the amount of TSB's concerning major parts of the car (ie high pressure fuel pump, turbo seals, clutch, pcv system etc)= not that great of an engine.

dont get me wrong, i love my car. but to think that the engine is stout, mod friendly, or extremely reliable is just naive. i bought my car brand new in 06, and have been on the forums since then. i have read just about every thread concerning these issues. perhaps you should go back and read some more of the success and failure threads before you tell me not to speak out of my ass.

[8.5MS3]

Target STI. not to stir the pot or add fuel to the fire but check out NASIOC, they have a dedicated blown engine thread just like we do. same with evo's. guys are blowing rex's n STi's at as low as 150 miles. every community has blown engines, thats what you get when some (not all) just bolt up every performance part and think they can forget about engine management/monitoring. increasing the output of a motor will always decrease reliability.

This engine won several awards. just because there are tsb's doesnt mean its a bad engine. it just may be tuned near the limit stock, and we try and push a bit too far. how many companies have tried DI + 9.5:1 compression + 16psi boost out of the factory? This motor is new to everyone, including the aftermarket. Things take time.

The reason there are blown engine threads is because a "my motor is good thread" would die in days. Companies are abandoning the platform because certain people (not all) in this community demand things immediately have no patience, while the rest of us sit quietly and wait. Its a shitty feeling to be a manufacturer and have people bashing your parts left and right because its not here "now", or its rushed into market before all the bugs are worked out just to shut people up.

To the OP: Its a fun car to drive and has tons of power out of the box. I would suggest keep it stock until your butt dyno gets used to it, then mod slowly, seeing how the car reacts to each part, rather than slap everything on in one shot. For me personally, an intake added 18whp, and a custom tune another 40 whp. car is plenty fast. anything more than 300whp and your getting a slimmer margin of safety than i would personally like to see.

its hard to deny the fact that there is almost a new motor popped every week.

This forum may never see it, but they are happening more then you imagine.

yes but how many people that have ms3/ms6 are actually on the forums? a few were lightly bolted i wont argue that, but the majority do have lots of modifications. MSF has several threads regarding possible causes. dont forget people's ego's come into the equation. how many people are going to admit "yea i mis-shifted and revved the motor to 8 grand....." or the like. much easier to blame others. not to say there is not a problem, just that this platform may not be capable of an additional 100-150 whp without a full rebuild...

hell ill admit my car started running like shit after i got a custom tune. i have a thread of that issue on 2 forums. turned out it was my own dumbass overoiling my filter and killing my MAF.

[Jacobra]

Seriously man. The mzr isn't nearly as bad as it's made out to be. If you put a bunch of mods on your car and have a lead foot you are going to blow the motor. That will happen with any car. Just throw on a couple bolt-ons and don't be a Boost-Slut. You can go for big power when it's no longer your DD.

[eg6motion]

how is this trolling if its true?



Yes, they all pop motors and if you buy a MS3 you are rolling the dice....
Give me a break, it's TROLLING. His only post was to piss on the MS3. The actual truth would be that more morons and kids drive their MS3's like it's a beater rental car, pushing it every day and modding it without any regards to warranty...then their car blows a motor and they whine like babies. I would be willing to guess that the true MS3 motor failure rate (for stock engines that were not abused by idiots) is probably less than 1% of vehicles. It's probably very similar to every other car out there... even Toyota Camery's may have an engine fail occasionally, but you don't see some asshat telling a potential buyer that their purchase will be "rolling the dice".

[8.5MS3]

Dont bother wasting your breath....6 months down the road he'll be on the blown threads...

major reason why people probably blow stock is that this is their first turbo car or first stick shift....guys think they can be cruising around in 6th at 45 and go WOT rather than downshift....yea 16psi at 2k rpm will cause engine damage. driver error, not the car's. or they think its a honda and rev it to 7 grand because thats what they did when they had vtak...

dont drive the car like a douche and you'll be fine

[SwampAss]

Everyone always remembers the motors that pop when someone posts. Keep in mind this forum and forums like it, have 1000s or so active MS3 members with no engine issues.

Also take into account that this engine is also in the Speed6 and CX7. That's tens of 1000s of DISI turbo motors in cars with no engine problems.
Engines are machines. I don't care how reliable a machine is, there will always be a few that have issues. If you are majorly concerned with whether or not an engine is going to blow up, stick to riding a bicycle. Chances are, you'll spend your time worrying about chain failure or steering neck bearings. :D

I have 45000 miles on my car and have pushed it north of 18psi. It's better than it was new.

you should listen to people who have more knowledge about this car than you do...its how you learn. its ok to be skeptical about info you see on the forums but to ignore anything that isn't in-line with what you want to believe is not going to help...

this is true and not true...

i agree the mzr is a great motor but adding a turbo that spools so early to it pushes it close to the max of its potential right out the factory b/c of all that low end torque.

first things first...you "keep off the grass" sign looks great and should keep those pesky kids off your lawn.

second...i disagree with your assumption that the failure rate is similar to every other car out there.

lastly...WARGLBARBL!!!!

When it comes down to it, 95% of the engine failures are either the result of careless modding or poor driving techniques. Or, most commonly it is a combination of both because you have the same mentality as an ignorant Honda driver.

[8.5MS3]

Look at it from a stock point of view. the motor is amazing for what it is. Mazda designed it for 265/280. if the motor blows when you up it to say 325/360 at the wheels, its not Mazda's fault. you simply exceeded the capabilities (factor of safety) that mazda designed the engine for. if the f/s was say 20%, anything more than 318/336 at the CRANK is beyond its design...

that doesnt make it a bad engine, its just doesnt have much potential beyond stock, unless you do a full forged rebuild.

yes they are.

w/o a tune my car put down 228whp/262wtq. after the tune im sitting at 265whp/315wtq. so assuming constant drivetrain losses. at the crank i am now producing 302hp/333tq. tires light up on demand in 1st and 2nd. thats enough power for me now....suspension & fat tires are where the money's going next

[Sp33dFr33k]

I've actually seen a few different articles rating the engine in top 10 of all time.

[Jacobra]

fair enough

however im just trying to illustrate that the reason people blow motors is that they put excessive mods on a car. that alone if they are installed well will not damage a motor to severely but when some one decides that they have to show off and race everything then yes they will destroy the engine.

by your logic if i strap on a turbo from a mack truck and run 50psi boost, as long as i tq the bolts down right and everything is connected properly i should be fine....

anyone else notice he repeats what i post??

[ericrapp]

I will apologise for my last statement. In my noob comments i mentioned about talking out the behind. I am very prideful of my cars. Sorry to help turn this thread into who knows what. And a personal apology to Target STI. I hope you will accept it sir.

[iBoost]

Just take care of the car and it will take care of you. And as long as we're talking about making power, most cars these days that come out of the stealership are 90% maxed out, so you really can not expect not to blow anything if your making 150hp+ on your average factory motor.. they're just not build that well to hold that kind of power. Obviously different cars have different weak points, so mod and drive smart and you wont blow anything up.
