ANOTHER VICTIM OF A BLOWN MOTOR
 

Thats right guys it was my turn i guess to have my motor blown. Mods r on the right and i was driving about 85MPH on the highway on 6th gear. Car began to sputter which wasnt uncommon and then next thing i know BANG! Smoke all over the place and oil all over my speed3!! Fuck! next thing I do is pull over on I-95 and find out all over the hwy and when i look under the car I see oil and and my oil pan cracked not to mention aluminum pieces all over the place. So car is sitting at mazda. Luckily, mazda knows my mods and even a corporate mazda rep saw my vehicle and let me keep 100% of my warranty.

that make 2 cars this week
my buddy motor is done also
bent a rod after a boost cut made by his crappy AP map :damnit:

Mods aren't showing up man, post up, we are interested

still find it very weird that so many spd3's going and so little spd6's... maybe its just me :/

last year about this time we lost over 8 MS6
look on 24/7

that forum is worthless, but im not saying it doesnt happen in the ms6 just seems that the 3 is more prone.. dunno tho

thats cause there is more 3s on the road =)
wait let me correct my self more kids with 3s on the road

nah man ms6's had a blown motor fest the beginning of the year don't know what your talking about. were all equally prone but theres gotta be more Ms3's running around then ms6's by now hence why we're blowing more often.

wait what the fuck? Your cars sputtered while cruising and you say thats common?

well if boost cuts are common then sputter must be common also =(

What do you mean by sputter? Fuel cut?

i think his pump is fucked
so when @ WOT it sputters dumping to much fuel in the system
making it hick up if that makes sense

Yeah sounds a little fishy don't it?

sigh, need meth and BSD stat

how long was your ride sputtering for? do you have dashhawk or ap logs showing what was going on? did you have pump internals? did your dealership or you ever look into why the car was sputtering at 85. What was your knock count usually when cruising at this speed, ( this is about 3,100-3,400 rpm's depending on the grade where everyone see's spme knock)

Is this April Fool's in December?

Let us know if you want to avoid this drama again. I'm sure we can work something out for that new engine you'll receive in the coming days in exchange for a proven forged engine. I wish this problem to no MS3/6 owner. Ok maybe the AP guys...I kid I kid...I've had three of my closet friends blow and it no picnic when it does.

Learn this lesson and do it right next time or leave it stock.

mods? flooring it in 6th caused the sputter? which is a big nono in my book anyway, fuel pump?

Well that sucks man, I am sure Mazda will not be thrilled to see mods on there. I would take off as many mods as you can before you can go. You should have looked in to that shudder a little sooner especially if you suspected that it was fuel related.

what a suprise, lol. what's that, 500 this year?

Perhaps the tune was to aggressive for the weather. Sorry to hear about the motor, what were the outside temps?

He's in Ft. Lauderdale and it's been about 70's - 80's all week...

hes in south florida i am doubting its weather related

shit beat me to it :)

Maybe I missed something in earlier posts, what didn't he "do right"? I didn't see a mod list for his car anywhere yet.
"proven forged engines"? where are they? I wasn't aware of anyone running one yet that was proven. (that takes thousands of hard miles) Randy's seems to be doing good so far, but hasn't had it long enough that I'd consider it proven. I might be way off here and if I am please correct me, but it doesn't seem that anyone one has a proven formula for this car yet. I have to admit that things seem to be taking off as we speak, but up till recently with a few finding from ptp and others no one really seemed to have had this car figured out.

^^^ Yah, you're kinda outta the loop.

Since I don't see a mod list just wanted to make sure you changed the plugs as instructed in the AP manual and had the OCC.

well....fill me in.

where/ what forged engines are you referring too? vague post like that help no one out. r u telling me that someone has a fool proof formula to do this engine right? I call BS on your post unless you can show references to support your claims. Coming back with snide remarks doesn't prove shit.

I'm really wondering if any of these cars with blown motors had the fuel pump TSB performed? I wonder if that has/hasn't got anything to do with it?

you must be out of the loop too, ask y2k cowboy he knows

Where state does he live in and what tune was he running?

I'd still like to see a list of the mods the OP was running...something often missing in a "My motor blew" post...

Yeah i'd say I'm pretty out of the loop. Been real busy and had zero time on the forums.

I'll just point out that this is probably where you went wrong.

Here's his mod list from his stats page. Says nothing about an ap on it and states he was running 15.7 boost which is really close to stock.

Im not sure how many he has built outside of robbie's CP/Pauter piston-rod combo, but i have sold AT LEAST 15 sets over the past year after we had CP make them. They are out there. I'll be using the same myself as well.

did he have an airflow straightener? Thats a lot of mods for the stock ecu to handle, also what about a fuel pump?

Maybe i type like shit, but it seems like my point was lost along the way. cowbay stated to learn a lesson and do it right. Where are all the posts from guys with that have done it right? I understand that forged internals are a must to go big with this platform, but it doesn't seem like evo had gone "big" I'd have to say with what we know now that upgraded fuel pump a tune and meth are necessary to help keep this car safe. Darksun has done crazy things with just meth and upping boost, but parts like pump internals haven't been readily available, meth is just becoming mainstream and no one has posted any long term results of running a forged motor. I'm not the frst person to say that if they are out there then where are they?

i dont want to give to much info not my ride
but it was 103 map

I respect that.
Thanks for the reply.
I only wanted to know the state so I could estimate the weather temps. Any idea what the temps were like when this ocurred?

-6

-6 damn that's cold. any idea how long he had let it warm up before driving?

I got kinda confused for a second. I forgot that there are two blown cars in this thread, evo's and mps's friend. Mps how modded was the car? stage 1 or 2?

MPS prolly meant -6 celsius...

Doesn't read like evo was in boost. Seems like the ususal part throttle engine vent.

lol...-6 c -6F both are cold as shit in my neck of the woods. :)
BTW....how much is -6c in farenheit degrees?

nah cruising at 85 usually means -8/-4 psi at 3,300 rpms. the same point where alot of cars get the partial throttle knock, stock/ modded doesn't seem to matter.

Yeah...that's what I meant. Reads like the usual part throttle venting.
Not sure about MPS's friend tho. Not enough info.

yeah it's definitely not enough info, I understand why though if he's gonna try to warranty it.

does anyone have an actual number for blown motors for 2008? people joke about crazy high numbers, but it doesn't seem to be more than 10-20 which still sucks.

I'm also curious as to what tuning solution the ppl with blown engines were using.
I know there have been a few that were bone stock but I would wager most were modded.
Actually, the percentages are not that high at least from the number of ppl that posts on the 3 forums. Don't get me wrong...one is too many in my book.
The more info we have provides us with the knowledge to pinpoint where the issues lies.
I understand why most ppl that have blown engines really clam up is because they are going for warranty work.

Damn, I just saw this thread.

So are there two guys in here claiming to have blown a motor? If so, please PM me with details so I can add you to the blown engine resource thread.

Well I finally got off my ass. At this moment, I'm about to drain my oil and pull my oil pan off. Gonna see if mine is a spun bearing or bent rod.... or something different....

damm sorry to hear..

Probably that the ms6 was only made for two years to the ms3's three years and the mazdaspeed 3's became the new hot hatch that is flying off our showroom floors. Its to the point where these kids are modding the shit out of them just as if they were a new srt-4(JUNK):damnit1: Wish it wasn't happening because soon everyone and there neighbors will own one.

so still no exact list of mods? FP or no?? no meth??

this always seems to happen-- people report that they pop motors and then dissappear for a few days when the obvious questions are asked...

Well it's not like they are obligated to keep us all informed. It's actually a big pain in the ass, and it makes you want to walk away from it all.

Well, gonna start my own thread.... I have some very interesting pictures to post up........

Bottom line... These motors should be made to take some abuse... How many sti and evo motors pop with 300 hp?? Mazda needs to recall this engine... new tune and stronger rods.. I have never had a car that has blown up stock or with small bolt-on mods.

Very interested in what you found.

mazda is going to recall an engine because a handful of people who have modded the engine have had it blow up?? that makes sense :ponder:

About 21 degrees F.

so 3 in 1 week NICE !!! :thumbsdown:

don't hold your breath

Yeah they are going to recall an engine because we decided to mod it? News flash, none of the factorys could give a fuck about you modding your car, not mitsu, not suby, not mazda, not chevy, not dodge. All they care about is warrenty work, if enough stock ones pop then the next gen will have forged guts, but if they hold together at stock levels as far as the factory is concerned they did their part and could give a shit about anything else. At least Mazda has got some parts out there that will retain your warrenty and still allow you to bump up the power a decent amount. Most factorys don't even offer you that much. If I remember mopar staged parts would get you to about 15hp over stock and everything past that would kill your warrenty time or void it all together. Again do not kid yourself, the factory puts good guts in the motor to protect themselves not so you can mod it.

sounds like it could have gone because of fuel, wouldnt adding a bunch of intake and exhaust bolt ons without adding fuel cause alot of problems? one thing alot of guys forget, more intake + exhaust = need more fuel (aka fuel pump + tune) this guy had neither so his car went boom

No tune= boom. He made a rhyme lmfao

lol jsut realized that:trink26:

I think the pistons and rods are fine for 300whp, i think the real problem is the tuning/fuel issues. Knock beats the crap out of engines. We are paying the price for being early adopters to Direct Injection...

Ive seen cars with much weaker pistons and rods run fine near 300whp

Whats the point of starting a thread if you arent going to keep people informed and answer questions? How does that help the community? If you want to walk away from it all, fine no need to start a thread on it until you are ready to talk.

its annoying because u get reminded of what happened. esp something like blown motor or something that prevents you from driving ur car.

It's understandable for people to be tight lipped about their mods/ what was going on when the engine blew. Some people don't want too much info out there because they may be trying to get work done under warranty, especially if the vehicle had only a few bolt-ons on it. we all know that mazda has been said to void warranty work for just having an intake, but who wouldn't try to get it covered under warranty if they can. Hopefully once work is done or warranty has been voided they will come back and explain to us what they had or pm the op and ask for the info. If your a known member of the forums you'll probably get the info for your own personal use.

Calm down Shakespeare. lol

that makes me fell more safe never heard of anyone blowing motor with piasini tune.....which means tune is very good......

no its just not enough people have the tune. what there's maybe 15-20 max

Or it means the tune hasn't done anything at all.....I keed I keed.

basically no one is safe, but you have to be smart about things, if your guna do more than a tbe/i you need a fuel pump, also to be safer you need a tune and fuel pump, to be even safer you need meth, bottom line this car doesn't give any room for error, either do it right or don't do it at all

My car ran like shit even with just intake and tbe, I say with just those mods you should even get a fuel pump and tune. mostly a fuel pump, i still think most of the tunes for this car are b.s.

Hey guys sorry for not answering your questions as quickly as I normally would. I want to post up the pix that the dealer took. Supposedly they are saying I blew my rods. I was going about 75MPH for those who wanted to know, on I95 and I was boosting about 5-10psi (which should tell you how much throttle I was putting down). The temps down here are in the 70's all day long. uhhh...yup thanks to the post man who put down my mods and yea it sux guys i fukin love this car to death and i def didnt think that it would happen to me of all people especially with the way things have been going for me. Im super pissed but its a good thing i been able to keep busy and not think abot it as much as anyone else would. I have my car at Gunther Mazda in Davie, FL and svc mgr there says that I need a full motor swap done being that I blew the Oil pan and I have a hole in the side of the motor about 6x6in. Total cost of the repair is about 8k. Im hoping the warranty still covers this but with my luck who knows. yup the motor in this car sucks and its dissapointing that it struggles to maintain 300whp without breaking a rod. I will try to post up pix guys some time this week you know things are really busy for me around this time of the year.

n guys if ANYONE is reading this and your speed3 or speed6 is sputtering/jerking while WOT you are in EXTREME risk of your motor blowing. Its just a matter of time. Little time. My motor lived only until 20,347 Miles.

hey man did you have fuel pump

Sorry for your luck, good luck with warranty work

what parts do you speak of? they stopped selling and coverinng the intake lllooonnngg ago. and stage one mopar was more than 15hp.

The intake will be back on shelves in two weeks. Anything past something that netted you 15 hp the dealerships started to downgrade your warrenty. They may still cover it for a year but that was a far cry from the 5 year 60000 miles your car started with.

It will? Where did you hear this? It has been off the market for a year, and even if you bought it back then it voided your warranty as far as I remember.

Irregardless, the they were gone for a year and didn't make your car much faster than stock. stage one srt4 is a better upgrade performance wise and they didn't "downgrade" your warranty. where are you getting this info from? This sounds extremely fabricated and basically sounds like you are just making things up.

You make it sound like mazda had other power mods, did they offer anything besides intake? I am curious. I know they had suspension mods and the like, but as far as power intake was all and it didn't last long. Is there a link that shows that it will be back in two weeks? They pulled it because they realized your motor could blow in this car from even just an intake. Clearly they ran the a/f rations and realized they made a mistake and were opening up themselves to huge liability.

word, you have fp?
you have any idea what your afr was when this happened?
from what i understand, the motor is around 5800 from mazda, are they also replacing other shit?
edited to add - HOLY SHIT!!!! 6x6?
that's a big fucking hole man

yup like 6x6 fukin crazy dude and uh no I never got the chance for the CDFP upgrade/ no idea what my AFR's were but im guessing they were lean as hell. That damn car. its not even the car its that crappy motor. fuck!:rocketwhore:

I called Street Unit the day before Christmas and that is what they told me. 2nd or third week in January. Add to that my Local Mazda shop said they had to, I repeat, HAD TO, honor your warranty if you used Mazdaspeed parts. They also said they would warranty my car for everything if all I have is an intake. Call up Bob King Mazda in Winston Salem and ask their service manager and he will tell you the same thing.


I got the Dodge info from the Top SRT4 tuner in the country who unfortunately isn't here with us anymore, Mark Riley, Daryll Cox's tuner. I was working under him when the SRT4 came out, Randy will back this fact up. We even had his memorial at Daryll Cox's shop. He used to laugh at the staged Mopar kits, until Dodge gave him some input on them. Maybe he was misinformed in the beginning but I seriously doubt it. Ford currently has the same policies for its line of motorsport aftermarket parts for the GT500 so it is not uncommon practice.

Last I checked every MSCAI dyno did report about a 15 to 25 hp gain. If you take my 242 and add in the least 15 at the wheels you are very close to 260 at the wheels with no other changes. You had to up the boost to get the same results from an SRT4 with a CAI to see similar numbers. If you need more than 260 at the wheels for what you are doing then Mazda warranties are not what you need to be worried about. Most other cars don't pick up that kind of power from an intake alone.

Mainenence?

I dont run a boost controller on my car anymore and with the bolt ons that i have, my car makes 18-19 PSI.

maybe i have a boost leak because im only hitting 15 at most and i have a cai/dp/rp, seems like everyone i talk to there boost went up?

Also no offense dude but thats a lot of mods for no fp, shit even i need a fp

i guess but it really isnt to me. idk dude pretty much full exhaust to me and intake. Its sad to me that a motor cant support so little. I think that even with the pump i woulda blown it. i didnt have any type of tune either. so complicated to me just doesnt make any sense. idk about the warranty issue but i think it'll turn out fine being that they told me about 2 months ago when i had it there for maintenence that the mods are fine. I did sign to that statement as well. so yes it was documented. o well they can still fuck me over one way or another. lol. I might end up getting rid of the speed3. Not sure yet. Still owe 20k.

and yes maintence to the vehicle was up to date.

Its not that the engine cant handle the power, its that people are modding and not taking the precautions to prevent this sort of issue.

Loosh hasnt blown yet. I dont think anyone who has been AP dynotuned has blown yet, we're making more power than the fully bolted cars and doing fine. PDXImport has ran many track days and has put his car through a beating and hasnt had a problem.

We all know the stock pump isnt up to par, you even stated that car would hesistate when loaded down, thats a good indication that there is an issue.

Sorry bro, but you had it coming. Im glad its getting taken care of, though.

so your winstom salem dealer honors it, you are lucky, it isn't mazda policy to honor it. and you didn't tell me anything about stage kits lowering your warranty in decending order, again, made up. stage 1 srt4's are faster than mazdaspeed 3 with ms cai. and i will believe mazda re-releasing the intake when i see it. i don't know why mazda would tell streetunit they are re-releasing the intake. and it will still void your warranty per mazda, which the mopar kits did not do, per dodge. hell, i think mopar even sella a warrantied supercharger for the hemis now.

and the thing with srt4's thats cool, you can turn up the boost and your engine doesn't explode. intakes did nothing on srt4's, but an srt4 with a wga and more boost, which costs lest than the intake, would be faster than an ms3 with intake. and they would both be out of warranty, per the manufacturer.

false dude i beat down on stg2 srt4's with just MSCAI. so i beg to differ. but it was pretty close. even though some ppl tell me there are stg1's that can beat stg2's.

another thing is yea i did know it was just a matter of time until the motor blew due to the fuel issue.

....i think its the pumps. Some folks are making near 300whp with the stock pump and a fair amount of boltons. Some aren't...like me...all i have is intake and TBE....my fp drops to below 1000.....my pump is in the mail. If ur getting a slight hesitaion/jerk/stutter under wot ur pump was not keeping up at all.

this thread has been an eye opener for me - i didn't realize the ms3 engine was this 'fragile'.

to quick ?'s:
1) with an intake (HKS) and BPV (Forge), i'm not really in need of a fuel pump, right?
2) earlier this week i did a shift from 6-4 and hammered it. the engine 'hesitated' but i figured the ECU was confused about me going from cruising to WOT; the hesitation time was about as long as when the DSC steps in, but the car pulled long and hard afterwards. is the 'hesitation' you talk about similar to this or while accelerating at WOT?

OP, i'm sorry for your loss. i hope your stuff gets fixed up under warranty and as quick as possible.

it sure sounds like you need a pump but idk how with only those mods

so the hesitation immediately following my shift IS what people refer to? i just figured that, given the drive-by-wire throttle, there was a slight delay before the ECU figured out what i wanted.

i haven't logged/monitored my fuel pressure, but, as you noted, i didn't think i had enough work done for it to be relevant.

any other input as to what i should do? and if i am at any significant risk given the minimal mods? the only thing i've done that wasn't ideal is that i got on it a little bit immediately after resetting the ecu. that said, i didn't beat on the car at that time.

Log your pressure, it's the way to find out.

if when it stuttered was right after you reset the ecu that is most likely why, what do you mean by a slight delay? its not a delay but feels like you floor it and let off and floor again but the whole time your really wot

PDXImportRacer was stage 2+FMIC and BPV and tuned with the stock fuel pump and he would get high load hesitation. Once he upgraded his fuel pump, the hesitation issues completely went away and the car would pull like it should have. The logs showed fuel pressure constantly decreasing as the engine was loaded, and IIRC, it dropped like a rock. I think a lot of people dont understand how important the upgraded fuel pumps are. A proper tune is also very important.

QFT

QFT. Honestly, anyone modding should invest in a data logging device (dashhawk, Aeroforce, Dashdaq, etc). Best $ spent on my car to date. I understand much more about the inner workings now that I can watch what's happening! IMHO, of course...

Yep I'm making it all up then. Not going to argue with you. I guess you know more than Mark Riley (all the tunes in the stages are of his design) about mopar kits and you know more about Mazdaspeed products than Streetunit does too. I will take your word for it.

EDIT: Oh and technically they are all illegal in California from stage 1 on, so its a moot point for left coasters. It don't just downgrade your warranty, it down grades your whole vehicle to being non street legal. I don't beleive many dealerships in California warranty vehicles that are deemed illegal for road use.
