In most cases it's out of pocket - especially if the vehicle has been modified. Look for a used engine.

First post and it's about a blown engine. THAT sucks.

Too late now, but anyone who blows up should read "Get Your Blown Motor Replaced Under Warranty!!!" BEFORE you go to the dealer, and BEFORE you post a fucking thing in the public section of a forum that has more private venues........
Good Luck.

hi i just came across this thread, last week i took my speed 3 to the dealer coz there's a vibration coming from the clutch pedal, they said it was a bad pressure plate so they replaced that under the 60K power train warranty. however, i pick up my car today the clutch paddle still vibrate when i lightly rest my foot on it... and there's a continuous (*thum noise) coming for the block....could it be like what you guys been talking about (bend rod? or the engine is on its way out?)

my car is bone stock with only MS CAI and 51K on it... if its really the bended rod, will it still be cover by the 60k warranty??? should i take it to another mazda dealer to them take a look?? or go back to the one that worked on my car??/

i'm desperate as hell right now....

Keep taking it ack to the same place for the same problem ASAP.
Then when (not if) it blows you have a record of
a) a reported problem
b) you tried to get it fixed.

Take it in ASAP
and as often as possible until either
a) it is fixed
or
b) it blows up

I actually just put my car for sale on cars.com because of all of this bullshit. I can't have my '07 with 5,000 miles blow a motor and because of a few mods be spanked with a $7k bill for non warranty motor work - it's my DD. Mazda FTL

[JimmyMac]

Gotta be willing to pay if you want to play. My 07 that I got back in December of 06 has been modded since January of 07. And the first mod was the XEDE which gave it huge gains (in the seat of my pants). Now I'm running a GT2871R at 20psi and no problems (so far).

Did you keep the Xede or change? If so how come you changed? I like the unit and would like to know if there are any downsides.

[JimmyMac]

Actually, I wished I kept it. But I sold it. I'm running the Standback right now. The Standback does more in terms of tuning. And controlling boost is alot easier by setting each psi setting for given rpm vs (whatever setting) you want. But using the software is alittle more tricky than using the XEDE software. From the get go, the XEDE came with a powerful tune. But changing the boost setting was a little more intimidating because you didn't set the boost with boost targets, you set it by guessing on the wastegate duty cycles. So it was a hit or miss thing. That was my only real gripe tuning with the XEDE. I sold it to try something different. I wanted to get a feel for what other options other products provided. I may sell the SB if/when Cobb offers the tuner software for the AP (if they haven't already, I don't read their forums any.) I'll try that out and go from there. I'm not loyal to any one brand. I just want what's best for me and how I do things. So it'll cost me $$ till I find one that suits me. Even if it means going back and purchasing something I've had in the past.

But going back to the XEDE, you basically just tune 4 maps. 1.MAF. 2. MAP. 3.Timing. 4.Boost Solenoid. If you don't mind playing with duty cycles instead of boost pressures, then it should be no problem for you. Also, you have to hardwire the unit in. I would stay away from the connectors that come with the XEDE and direct solder everything. Unless of course if you bought the PG PnP wiring harness. Then you just solder into that. You would also need a cheap serial to usb adapter to tune it. But that's only like $7.

Hope that helps. You could try some of the Aussie forums that are out there. They love the thing and could answer your questions better.

[JimmyMac]

I added Oil to the list. So if you remember what oil you were running when it blew, please post up.

[phillyb]

when i first fucked my car up, i took it to a shop called turbo performance inc in van nuys, ca. they had another ms3 they were working on.
they made an fmic, 3" tbe, and a turbosmart mbc.

i went there to pick up something for my car and this is what i see...

[JimmyMac]

Good pics. Any info on how it happened?

[phillyb]

piston, rods, idk really what that is...but that's what they muttered. i don't know if there's a gauge in the car, and i don't know the boost, but i'm assuming it's a lot. i would hope it's not WAY TOO MUCH.
i would like to contact him, but don't necessarily want to take business away from the shop. hahah

[JimmyMac]

I added myself and IDRVSLO to the list.

[JimmyMac]

My problem might of occurred about a week or two ago. I had a spike of 30.8psi for some odd reason. Never done that before. So this might of been the catalyst of my ticking. I can only speculate. But anyways, I have my own thread for my troubles. I'll know more as I pull the engine apart.

[ASIC_BSEE]

So with woosh, darksun, laloosh all running fine with tons of power and lead feet, is the key to drive the car hard ? Just kidding, but think about it, those that have blown have been easing into the throttle, maybe hitting the throttle hard forces the ECU to ramp up the fpr faster, injector duty cycle faster, and get into richer territory faster. It seems a little strange that these cars aren't blowing at WOT, but are at minimal throttle. Also, I bet most cars that blew had a recently reset ECU or reflash.

It's got to be the closed loop to open loop transition and pre-ignition and/or detonation. On a newly reset ECU, the fuel trims aren't adjusted enough to keep the car rich under boost, even mild boost. As soon as you start pushing the gas pedal its still at stoic, especially if you haven't given the car enough ignition cycles and driving time to get the trims right. Look at the dyno graphs for a car that was just reset, AFR reacts so damn slow, that it doesn't even get to 12.5 til 3500-4500 rpms WAY after full boost has kicked in. Take this and a newly reset ECU and you get pre-ignition one time, you just broke a rod.

Lean AFR, hot engine, can ignite the gas at BDC. Maybe even throw in a burnt valve or improperly seated exhaust valve to supply the ignition source. Hell, maybe even all the carbon build-up on the intake valves is acting as a glow plug.

I really don't think it can be the balance shaft. If anything, the balance shaft connection is creating a hard point at cylinder #3. If it has to go somewhere it will go in the spot with the least give. The balance shaft is creating a torsional force against the crankshaft.

I`d like to see boost PSI at time of break down added to the list.... Just for arguments sake.

[Lex]

With these weird vibrations people had before blowing up, and then doing so at low load, could it be something in the rotating assembly falling out of place? Anyone considering the balance shaft assembly as a possible culprit ... something "stalling" the crank?

all i know is that the balance shaft is on the 3rd cyl

[oskinosmee]

BSR might be a good prevention maybe? If so i needs it lol

[Darksun280]

from what I understand incar vibes might be a bit much for most people

I wouldn't care if the bsr was a slight chance to help the engine stay intact

[Renzokuken]

<----35k 18-20 PSI since the first month of owning the car TBE/FMIC/I/ still no problems. But I do knock like hell when Im not on the 100 octane.

[CMESCOOT]

If i'm not mistaken, All of the big turbo guys on here are using the standback.
And as far as the rpms flying off the charts, that has nothing to do with it. Myself as well as a few others who have popped their motors, did it while at highway speeds at low rpms. I personally was going 75 miles an hour on cruise control on a completely flat road in 6th gear, then BOOM! There was a hole the size of my fist on both sides of cylinder 1, and a chunk of it tore into the coil of my alternator, busted a hole in my radiator, and cut a hose. From what I've read, there is a problem with resonance in the motor at low, constant rpm's that is making the rods snap.
Someone correct me if I'm wrong.

[ASIC_BSEE]

Vibes in the clutch pedal are from an offset balance on the crank shaft caused by a bent rod. Rod being slightly shorter offsets the balance of the crank. Eventually the rod will break.

Bent rods are from Pre-ignition close to BDC when engine is hot, AFR is lean and boost is rolling on.

[JimmyMac]

Updated, more info to come soon.

[ASIC_BSEE]

So, I was at Milam Mazda in puyallup, WA yesterday and asked why the Black MS3 with a front mount IC was there. The service manager said it had a hole in the block. I know the guy is military and deployed and his friend had it towed there for him. He also said it happened while driving under a bridge; just oil light came on and car stopped. Anyone know who this guy is? Like to get him added to the list.

Christ imagine how many blown motors there are out there that arent reported ont he forum......

[mouse0330]

wow, can't believe that many motor is blown, just want to know the people that had their engine blown are telling the truth about their mod. Lets not forget that our engine is still consider new technology. This is not like the r32 engine that you can mod all you want and get outrageous hp. We are still test rats in this market for our 2.3 disi turbo engine. Haven't heard of any regular 2.3 non turbo engine blowing up yet. Have anybody? There are heavily tune engine out there with no problem. Mine isn't even modded that much, and I drive like crazy, hit a huge dip on the road without know it was there, that was how fast I was going, even hit curb hard during purring rain, replace 2 bad wheels, one was bent. I still drive it hard, almost everyday, I hit into 3 digits when there is no car car around

I know this guy and have talked to him a few times. He was running 25 + psi on the stock fuel pump with full bolt on's. I forget his name but I did tell him to take it to the dealer, hope they cover it for him.

And that guy though his was was running good? I guess now he knows he wasn't.

[JimmyMac]

The anonymous one is an over seas MS3. Meaning, not North American. I'll update later tonight when I get home from work.

[bf360]

funny i go to get my car towed to a shop from where it was at the dealership and i look at a cx7 there working on and the heads on the floor and i was looking at the pistons lol

[mlassek]

add me to the list of shame.

bent #3 rod while shifting into 3rd at 3-4k rpms mid boost.
mods are listed in sig but with pg intake rather than the txs listed.
only seen mobil 1 oil until i put royal purple in last week (5-30)

[boosted3]

yea im going meth also seems liek people wiht meth havent blown there motor at all.a good tune wiht the meth at lower boost levels should give us the upper hand on the popped motors.Darksun big turbo most likely goign on after the holidays

I still don't know about that, there are a lot of ms3 out there and only a few/ very few that run meth. So odds are favorable with meth users but there are tons of ms3 out there that are running fine without a problem/blown engine. Can we find out how many ms3 are sold since 2007, I think we need a consensus going if one haven't done one yet, I know we have one for blown engine.

[oskinosmee]

I think my motor might be gone. I have Meth and a tune

Fuel pump? What PSI/turbo?

[oskinosmee]

Originally Posted by badams118 Fuel pump? What PSI/turbo?

Im not blown yet i think Darksun is right about the injectors.
but yes i have looshs fuel pump, 20 psi stock turbo. Snow meth kit
