It finally happened
 

Blew my motor yesterday afternoon. Ironically enough, it was while I was headed over to Cobb to check out the engine build on another local blown Speed 3. There was no prior warning whatsoever. I was 1 block away from Cobb, turning onto their street when it happened. I was accelerating in 2nd gear just getting ready to shift to 3rd, boost was around 2 or 3 psi, and it happened somewhere between 3500 and 4000 rpm. It very forcefully blew up, I thought the hood was gonna blow off the car. I had just enough momentum to coast the rest of the way to Cobb and pull the car around to the back of their shop. Haven't had a chance to really look it over, but there are holes in the block front and back. Couldn't tell if it was cylinder 2, 3, or both. Backtracking the massive oil trail I left, we found some large chunks of engine block in the street. At this point, I don't know what my plans are. Car has 63,085 miles on it. Current mods are in my sig, and have been there for a long long time. The car was only stock for 12k of those miles, and pretty much fully bolted for the past 40k. I did the BSD last November/December sometime, I'll have to check my records to find out exactly when. I'm gonna head back up to Cobb today to get a better assessment of the damage (with pics) and maybe figure out how I plan to move forward.

No good.
I found you by following the oil trail

That hole behind the starter tells me #3 went for sure.

welcome to the club :) For all it's worth I put my car back to stock had it towed to mazda and got a new engine and turbo.

Sorry to hear dude.

moment of silence ... alright, let's talk about rebuild plans!

he's out of warranty

Well you did good for a long time. I know we had our bickering in the past but I'm sorry this happened to ya. BIG decision time build for 6-7K or put a stock motor in and trade for 3-4k

wow thats some ironic shit that u just made it to cobb lol. i guess christian got a solid first hand look at it haha. sry bro. i say call it a good run and use this as an excuse for a new evo.

can't blame the balance shaft on this one.

Not sure if you were monitoring...but was there any knock before this happend?

Did you just get off the highway? Was there a long cruise before hand?

Sorry to hear bro. :(

Good luck with everything...

Now it's Evo time. :)

Did you have a catch can?

.....to catch all the parts?

Sorry to hear this but its evey week this happens. This fail boat of a car is just a big disapointment..I really wish I never bought this car in the first place. I dont know of any other car that has had so many blown motors and to think that this DISI motor won motor of the year a few years ago.. What a joke.. If we put all the money we put into this car into a mustang or evo we would be running 11s or 12s all day long and not be worried about blowing.

It hasn't been on a lift yet, I was there soon after it happened, they pushed it into the shop just before closing time.

Christian is at the Salt Lake City location, we are in Plano. Though the lead tech at Cobb down here owns an MS3 as well.

This shit scares me, its getting closer and closer to me. Keep yours in one piece superskaterxes!

you had a good run dude. thats a good amount of miles for being fully bolted. let us know your plans.

I don't see it in your sig, but did you have a PnP intake manifold?

my speed6 held up well. ?! :P s

I'm not going to curse myself with that kind of response.....

the reality of all of this blown motor bullshit is really starting to set in. someone needs to figure out why this is happening so i can stop thinking about parting out my car. =(

damm sorry to hear bro! :(

Honestly you should just accept forged motors don't blow stock motors do. When you boil it all down thats where we are at. When you buy the car if your gonna heavy mod it your going to have to build it first or have a spare block ready.

The fact that even building your motor doesn't yield you anymore power or give you the ability to make more power then a stock motor is just icing on the cake. Its called a lose lose son or better known as damned if you do damned if you don't.

exactly, im not motivated to dump the money into building the motor because the car wont be any faster. if i could have the kind of power that we should from a gt30 and a built motor id happily drop the money right now.

That motor lasted for 48k miles at 350+ ft lbs of torque. It did well.

Pics and assessment of what happened would be great.

The catch can question is quite valid - from his sig looks like he didn't have one.

Oh I know. I was trying to be funny and evidently failed.

No, he did not have an OCC.

sls, not happy to hear this but, its the risk we all take. look forward and dont dwell on the whys.... good luck with getting it back up and running man. if you need resources or anything i can do within reason pm me, we should all be here to help each other when this happens to one of us

I doubt the catch can would have saved him and I doubt he had any KR damage.

The fact of the matter is, no one knows why these motors go, they've gone with no KR, with catch cans and with meth.

Still a toss up it seems.

geez, everyone is so sad and shocked and pissed and whatever. get the fuck over it. this shit happens regardless of what car you have. you mod the car and change the dynamics of the engine and this is a potential result.

perfect excuse to go built, go stock, or hang up your belt. brandon will be back either way it goes.

fixed.

sorry to hear man...hope you get back up and running soon time!

at least you made it to A shop...rather than being 800 miles from home...

Not so sure about that. He had 63K on his motor, 40K fully bolted, and he stated he just removed the BS last December.
If, thats if, the BS has anything to do with these motors popping, I'm guessing he still had it in for 50K miles.

Sorry to hear about your motor dude!

Lols, can you explain how a the BS ghost locked up his motor?

Honestly, I said it before and I said it again, why are so many of you people surprised that this motor blows when you start modding it? His internals were stock with nothing but bolts on and to do as many miles as he did is quite impressive.

This whole paranoia honestly is getting quite ridiculous. How many people are there with speed3 that DO NOT JOIN FORUMS?

This is what happens when you slap bolts on and push the motor beyond it's tolerance... why is that so surprising still to some of you? If you don't want to blow and have this as your end result build your motor first before going the "bolt on" way.

To the OP- you had a good long run. Heavily modded engine with 60 or some shit miles is pretty good. Build that shit!

is there anyone on this board that built their motor before blowing w/ the stock turbo? I am curious.

sorry to hear it man. update the resource thread when you get a chance.

glad im on my way out of this shit box .. good luck with the new motor or new car homie

Honestly I don't know so I can't say yes. However, from what I have seen everyone went the bolt on way; whether it's on this forum or any other forum for that matter.

damn bro sorry to hear about it.I also blew about 3 months ago i bought a cx-7 motor now and im basicallyback to stock except intake turbo inlet and cat back thats it.and the car feels nice lightly modded.But im gona trade it in scarred of blowing again

So the balance shaft delete didnt save this one huh? Scratch that myth off the list.

Sorry to hear you're scarred. Chicks dig those though.

Gonna head up to Cobb shortly to take a look at the carnage. No catch can, but I've never had a real issue with the PCV system especially when compared to Aaron's car. Wasn't monitoring knock at the time, had the AP set to display AFR. I had been at Discount Tire a couple of blocks away from Cobb getting a bolt removed from one of my tires. I haven't decided what I'm going to do yet, but I am for sure not getting an Evo.

Balance shaft has been off the car for a good 25k miles at least. I've racked up that 63k in just barely over 2 years.

i hear the yaris with nitrogen in its tires gets really good mpg's

Lex, love what your doing here and other posts in trying to figure out these causes!
I did'nt say the BS locked it up! Didn't say it didn't either.

What I meant is:
OP obviously ran his BS installed for probably 4x,xxx miles before removeing it. Most of those fully modded! IF, thats IF, the BS is causing extra stress on the rods/pistons, that stress has been going on for quite some time!
Didn't you post in another thread (Kaboom!) how rods give way after x cycles? Excellent post and link you provided by the way!
Rod fatigue, I'm guessing, wasnt magicly cured by the removal of his BS at 40K miles.

What is strange is the ammount of people popping while in the middle of a shift!! Has anybody researched this?

Wow! must do lots of driving! Thanks for clearing that up!
Look forward to pics and thoughts.

That blown motor thread is missing almost 30 cars. yes I said 30. I got depressed updating it so I just stopped.....

now all of a sudden I see myself thanking god instead of cursing him for making my car so underpowered.

242whp ftw bitches!!!!!!!!!!!!

Sorry to hear bro!

I think I am going to keep the engine stock...

for the record--all of you guys saying that 60,000 miles is a good long run, thats fucking stupid.
Any motor that blows with only bolt-ons before 100,000 needs to be looked at carefully. you can find hondas fully bolted, turbo'd with no/bad tune and driven by a 17 yr old retard that boosts in to a parking spot that will still last 125,000. sorry to bust balls but if i wanted a car that would only last 60,000 miles i would have gone with a GM pos.

btw: if cycl #3 runs leaner than the others and a AP leans out your mixture with their pre-set tunes why are we not looking further into this?

I wonder how many have blown without a tune compared to people with a tune...

Thank goodness for my stock tune :)

looks like what im sticking with...

^^^^ nice rep power. and 60k miles aint shit..... 100k on a honda and I still consider that a half life engine at least.

let's race to 80k.... I got another 17k to go.

people still trying to make bullshit excuses
oil catch cans
balance shafts
60k is a long run
btw he was not making 350wtt for 48k, so throw that out the window


ill say it again, the motor is weak, the end

well add to it then lenny...

So you need to back-up and explain... How would your car not produce more HP and Tq on a full build? Full build and stock or piggyback ECU, or full build and AEM stand alone type build?

i have my balance shaft still and no catch can ever.

other than exhaust manifold all other bolt ons are on the car. tune holds 20+... car knocks like a motherfucker and i spray 100% meth.

i expect NO BOOM

86k miles here.....

no shit? damn alan..u the grandaddy... whats the eta on your boom?

I've been running on borrowed time for a while now.....................

I noticed by spraying 80-90% meth by boost temps and knock went down significantly compared to 100% meth. If your getting a shit ton of knock you may want to try a little water. Not saying go 50/50 that sucks but by adding some water seemed to significantly help without hp loss...

continuing onward with bsd and baffle in this case

i aint mixing nuttin.

100% meth = manliness = hair on your chest

has anyone checked (or cared enough about this platform to check) individual cylinder temps?

Thestaplegunkid posted some detailed pics of a cracked piston that may have seized causing the blow. I am curious what is found out here.

Engines that fail at low load are either because they are fatigued from endured stress or because something goes wrong with the engine at that point causing it to seize. We've seen a lot of twisted rods and what appear to be seized motors. And I don't think the BSD is seizing these motors.

davesxx01 I apologize for coming off as rude.

I don't care how many blown motors I hear about im getting a tune to 24 psi tomorrow. I'm a skydiver so I do not live my life in fear. just because 9 out of 10 smokers die of lung cancer don't mean you will. every single car and part on the car has a diff molecule structure made from a diff pot of multin metal. I just hope mine is made from the good POT.

I want some from that good pot too...

oh wait...we're talking engines here...er, what he said...

you may not care about how many blown motors you hear about but do you care about how many numbers you see on your dyno after you add meth, SST, and mani? lol.

100% tru especially when im 6 Grand more invested for 30hp and 20tq over a friggen SRI with a tune

Should have gone big turbo on stock internals. Lord knows its better for your engine. /sarcasm

That's the spirit!

see threads like this is what worries me about getting this car.

Your not in wonderland anymore once you joined this board. Shit that makes sense on other port injected platforms doesn't fly for 4cyl cars using DI.

Bold and Brazen just the way they like it. Mazda gods prefer their sacrifices this way cause the stubbornness and struggling makes the offering that much sweeter come time of boom.

I know you keep an eye on this - how are the DI Cobalts doing?

They are stuck. Their fuel system is slightly better then us so they got a bit of a higher hp cap then we do with their smaller motor they are in the same leaky boat. GM has had DI tech longer then mazda though. Cobalt guys wised up though and once they get above 330 whp they started to concentrate more on power to weight, suspension, and traction and are more focused on their Et's then their dyno numbers for now. End of the day no car is fail if you have a quick ET.

In the car world we sometimes forget we try to make these crazy HP numbers so that we can run better times at the track. Our community is so preoccupied with blowing up and getting high hp dyno numbers we don't have enough gutted, slicked up soldiers going to well preped tracks trying to salvage our dignity. I am a culprit of this as well.

Any strange issues - leaking injectors, blowups?

And there is the kicker NO. Only guy who blew up was a guy like our Sock's who dyno'd like 450 on spray and blew up cause of a poor hack job tune while running down the 1/4. GM is smart though the bottom end is the same shit they made back in 99 or 00 for the super charged cobalt and that bottom end was tested to 500bhp stock so the cobalts don't go around blowing up shoping for groceries or getting getting milk while in a parking lot or down the block from their favorite tuner. Any way if you've noticed the way di mixes the fuel its hard to run lean from too much boost cause it can dump enough fuel on command to raise a Battle cruiser. Don't mean its a mix proper for making power though.

There are no real high milage high modded ones yet though so we have to wait for that. My friend over here with his GT3076 one though is quite content for now with his 380-390whp though he know at his cars current weight that's enough to put in work on the street or track with proper traction. They already have a wot feature and 2 step timed for slicks so he's fine.

Man, everytime I start to feel comfortable with my car again, a thread like this pops up. Sorry to hear SLS, hope you'll be back up and running in something better soon.

i will be going forged before this happens to me.

boxyyyyyyyyyyyyy

god her voice is annoying.

what exactly did you mod to have that result. Excused my noobness.

he did the mod no one should ever do. He did the "part throttle boost" mod

Finally put the car up on the lift. There is a huge fucking hole on the back of the block. There's a small hole in the front directly opposite. The turbo oil return line was in the line of fire and broke off as well.

cough fastest stock turbo MS6 trap in the world cough

damn that rod got pissed and said fuck you i'm outta here.

LOL

*Cough* I said ET not trap *cough* lol

thats aN AWSOM blow up BTW. ur rod def said fuk this

ET's are for bitches, trap is where it counts.

my 2 cents
 

nvm

holy shit.

look on the bright side OP. now they can work on ur car from the outside without removing the motor. then when they are done a little JB weld to patch the hole and walaaaa 400 whp

yeah your rod just lost the 60k mile long arm wrestle.

funny you can see that big retarded balance shaft gear there just pointing and laughing at the rod next to it that got owned.

wait why are the teeth on the bs gone a little. why is that?

cause he prolly didnt get the opportunity to remove it till he was like 40k miles in lol...

You going to tear into that and see what went on?

You nee to go back to the start of your oil puddle and see if you can find the rod sticking out of the asphalt. Jesus that thing packed its bags and made a nice door for itself.

Bye bye my 3 brothers, Ive had enough *SLAM*

i wonder if its the same cylender in all the blow ups. we need to look into this. maybe its a mazda defect on that specific cylender. we need to direct inject meth into that cylender and have a start of 2psi and full at 5. that should rid us of blow ups

I don't see you working for COBB anytime soon dude.

It's not always the same cylinder

then we need direct inject meth in all cylenders all the time

dont have pumps that will work forever.
meth will eat away at seals and shit.


they do have this thing called race gas though...
