I'm glad that you're able to get that fixed under warranty, although they're probably picking through the pieces to make sure they somehow dont cover it. lol
But if there's no high boost from an EBC or MBC, no additional mods, moderate daily driving, and only one owner (I'm assuming), then it might've been cheap gas and that one fatal detonation that bent a rod and sent it shooting through the floor. If not.... then just blame the Mazda gremlins and call it a day.

You cant blow your engine on stock setttings unless you drive like a idiot.
maybe it was bad maintence? poor oil or bad tank of gas? Looks pretty dramatic to be anything stock.

I developed a rod knock in my N/A original motor at 85K. That motor is now sitting on a stand in my garage waiting until I get the money to have MAM "build" it.
So I'm inclined to think its either weak mazda parts or Arizona gas.
Kyle (wildwolf) is on his 4th motor in his 2003 MSP all replaced under warranty.
Scott (zzoomzoomm) orange MSP is on his 4th or 5th motor.
Clay (zoomzoom02) Protege sedan is on his second motor that I know of.
Aaron (EmRidMSP) is done with his first motor
I'm on my second motor.
So all together thats 8-9 turbo'd motors and 2 N/A motors that have blown up in Arizona over the last two years that I know of..

metal doesn't just break in to those little pieces unless there was some serious stress, like running really lean but stock msps are notoriouly rich.
To the questions about gas - it's a forced induction engine. Gotta run the highest octane possible - which around here is 91oct. I had been runnin this tank of gas for about 100 miles with no trouble.
I had problems with detonation late last year. I fixed them by changing my spark plugs (they were completely fouled). I also had problems with getting CELs saying that "LEFT BANK LEAN." That went away when I changed plugs, too. I switched to Iridium IX's (ZFR6FIX-11). What I believe happened is that the detonation last year weakened a part of the block and then the first time it went this time - BOOM! I took it to the dealership 4 times to fix the detonation and they "couldn't duplicate the problem." Well the smart.com guys at the dealership didn't get it that after a few visits with reports of detonation and never "fixed" the problem. They'll see this when they pull my service history.
To the comments about me over-revving my engine or being a dick to my car... hahahaha nah. I DO track the car, but I drive the car like a normal person day-to-day. I haven't had it on the track in about 4 months and not since it had detonated last. I do my own maitenance, too. Change my oil after ever "hard run" or 3000 miles.
I can honestly say (even though this IS the internet, you can only take my word for it lol) that there is no reason this motor should have blown.
I dunno. I'm sure that my posts don't convey exactly how pissed I am about it, BUT..... hey... gotta find the bright side of a situation: I get a new engine, right? I am planning on doing some mods in the very near future and I'm gonna have a brand new engine to work with. I'm sure my disposition would not be so damned "sunny" if I wasn't still under warranty. lol

You can but highly unlikely...and not many people.
What happen in the old days were Joe P FPR (leans out the mixture) and crappy MBC.
You have to think to raise the boost and you should not raise the boost unless you have control over fuel. Which is why DSM's AFC, Megasquirt, Mircrotec, Emanage, AEM, Unichip and etc are always a good investment for our cars. MSP run rich but they also are prone to deontation at higher RPMs (weak fuel system and high compression) and more boost requires more fuel to reduce detonation.
Smart moding is the way. There are plenty people like me who arent stock (or stock boost) and are on the original LSD, Tanny and motor. And I dont plan or expect a blown motor or tranny anytime.
I drive the car everyday and I bring it to the track....not drag racing but a good amount of autox and road racing including seabring.
My STOCK motor blew at 3800 miles...Explain the bad maintenance there...I also Ran 89 on 12 PSI for a long time....If the ambient was 80 degrees or less with never a problem.....mine didnt blow apart like that thing did though....(boom07)spacemonkey said:

I know how you feel Aaron, but my motor wasn't under warranty.

WEll Im at 48,000 miles on stock engine and tranny...explain that if the protege motor is so prone to blowing up at stock setting. im not the only one that have reached 40,000 miles problem free. 5,000 units made and how many have blown motors and tranny? The local Mazda dealer ship has probally done like 2 MSP motor swap and that was the same person who drove like a idiot.
You can run lower octane if your out of boost...but your telling me its okay to run 89 octane at 12 PSI with ambient temperature of 80 degrees on a motor with 9:1:1 compression? and on a fuel system that can flow enough on stock injectors to go past 12 psi at redline. Remember what unichip/pinapple racing said about our motors and why they decided to program the EMS to spike at 12 psi and bleed to 9 psi towards redline? You must have been detonating like crazy at 5,000 RPM if it holds 12 psi to redline on 89 octane gas. a good boost creep or minor spike and their goes the motor.

It definitely looks like a piece of the rod, a sheared rod bolt, and chunks of shattered cast iron block.
I agree wholeheartedly about the part throttle lean condition around 3500-4000 rpms. I've been experiencing it for a while. Now I make sure to give it enough throttle so that doesn't happen.
Good luck with it, man. If you were truly stock, Mazda should cover that.

Well, they are gonna ask for proof of all scheduled maintenance. I don't know how that works if you do it yourself because oil purchase receipts do not prove you actually changed the oil. I've already been through that whole procedure. I'm not trying to sound like an ass, but just be prepared for the dealership to try to get out of fixing it.
You think what you want but that motor was not detonanting...and I never ran 89 if it was warmer than that....I was making a point that BONE STOCK motors do blow...Mine looked nothing like that and actually still ran to pull it onto the towm truck but it was toast...Motor and turbo were both replaced...I do beleive I had the first "OFFICIALLY" blown MSP motor on this site...But I do agree...For most cars @ 12PSI would have problems...My car was a bastard child..The second motor had manymiles on it....30K with upped boost....Yes they last and dont Just blow normally...I agree and never tried to say otherwise..pretty much I totally agree...With the exception of your opinion on the fuel.spacemonkey said:

ironically enough an old lady came into work today (i work at a local lexus dealer) with her 160k mile 98 ES300 who does every maintenance exactly when scheduled, and drives (like previousely stated) like an old lady. she somehow got the #6 cylinder to detonate which fused the plug to the head and there is a nice pretty hole right by the plug where you can look in and see the piston. so interestingly enough, wierder things HAVE happened.
oh and btw, to correct a previous post, msp's have a 48mo/50k warranty, not 36/50
