mods..?

[holeinmypocket]

me i was fully bolted on a reworked k04 with stock tune = bad idea

[wruss64]

I just went through the warranty hassle, 2008 MS3 GT, you can see my posts earlier on the page. I will say that it will probably take 3 to 4 weeks for you to get an answer. Was the car modded? If not the claim may go faster. In my case it was not Mazda's fault, nor the engines fault, that may have made the decision time a little longer. But, new engine is here now, should be put in today. If you have any mods at all, take them off and go back to stock if you have any hopes of a warranty claim !

[evidence]

Hindsight being 20/20, it's a good idea to grab some small rags and fill all open holes (haha..) while your working. With everything left open your just too susceptible to your unfortunate experience :/ Goodluck with the new motor !

Hey guys, I realize this is the gen1 forum but there's conflicting info in the 2nd gen forum.

does anyone know if a 2010 has blown yet? Also did they change the rod's in the 2010? There's conflicting info with regard to rods and the only response I received to my inquiry was a troll post. Thanks for the help...

[phillyb]

don't think a genpu has blown yet.
honestly, i can't fucking wait for the day.
the rods thing is up in the air still i think.
i'm voting for no change.
same engine, same rods, same fail.

Thank you

That still may be ok, I'm just not happy with the Si that I purchased last August. Really wishing I had gone with the mazdaspeed. So I may have to do that at the end of the year. The percentage of cars blowing up seems pretty small and in almost all cases they were modded pretty good and in many cases ECU's weren't properly tuned.

i think that the genpu aren't blowing up cuz none of them have gotten fully bolted or BT on stock block

[Lex]

It could very well be the new ECU and tune for the 2010

[Spoolme]

That sucks Wruss64 I feel your pain bro

[kwsmithphoto]

Ya, Lex, the motor does have a new ECU but same power ratings. If anything else changed, Mazda is on the DL about them.

FWIW, I've only seen 1 genSmiley MS3 on my travels through LA since they came out. I suspect low demand.

Keep in mind that there are what, about 15,000 just in in North America, not including the MPS, which is essentially the same car? It's going to take a couple years to see if the newer, slower car is less prone to kablammo, especially since it will be a while for the aftermarket to learn the new ECU and other changes in the engine bay packaging to optimize their wares.

But don't hold your breath, I've been seeing a LOT of new GTI's. They look pretty sharp and are much more competitive with either gen of MS3. If I were cross-shopping today, as opposed to 18 months ago, probably wouldn't be here. But I wanted to buy a car, not lease one, and would never, ever -buy- a new VWAG product, especially in it's first year.

Anyway, I just don't think there's a large enough user base of genHappy MS3's around to make any comparisons with drivetrain issues yet. Meanwhile, I'm keeping my 2009 motor bone stock until the warranty runs out, so if anything bad happens, it's covered.

Simple as that - take it back in to the dealer. That being said, I have seen many DISI engines blow and I haven't seen any that lost valves like your first motor did which looked like a timing chain/mechanism issue or severe over-rev.

I thought the rule of thumb was to only load up after 3k for anything, including stock, no?

Originally Posted by kwsmithphoto I'm inclined to agree. I really, really like my 60K powertrain warranty, and intend to keep it intact.

If I want a faster car I'll buy one...if or when I can afford to. But if my very well maintained stock motor blows, I'm covered. I need that. This is not a race car! And FWIW, I take no "special care" to avoid the RPM and throttle input zones where most engines let go. Why should I, it's an un-modified production engine that's never been abused, just driven like any other car I've ever had. And as you can see by the Fuelly graphic in my sig, I don't drive it like an old lady, because I get god awful gas mileage just keeping up with traffic, and occasional forays into non-competitive track days just for fun. So if the motor let's go and there's a warranty "issue," Mazda will lose if it comes down to a fight. I know how to deal with shit like that. BTW, did I mention that my motor is stock? BTW, I still love this car!

+1

Sick and tired of this nonsense about the car. I'm losing too much sleep and cramping up my foot and wondering why this car has been so uncomfortable (It's because I've been pussyfooting it). No more. Dashhawk stays but I'm not staring at it anymore for any anomalies. I'm just going to drive it.

[kwsmithphoto]

Yep, that's what I do. Works well enough so far.

My last track day was on a small course that's almost entirely curves, and almost entirely 3rd gear in this car. On most corners I was feathering from 2800rpm to 3500rpm much of the time, both part throttle and WOT.

It didn't blow up and shows no signs of doing so anytime soon. Still managed to pretty much shred a set of Star Specs though thanks to wheelspin and a fairly abrasive surface though.

Once more available cash comes along, after an imminent tire change, I really want a Mazdaspeed intake. They aren't magic but they do provide a notable increase in power, that doesn't automatically void the warranty or throw CEL's.

That's about it though, I'm far more interested in street-able handling improvements. I like what I got but there's always room for improvement!

Besides, I've been doing some landscaping lately. Hauling 300-500 pounds of bagged construction sand around town, well, that low end torque is pretty useful, especially up hills.

Point being, I think the motor is pretty wound up from the factory, and has more than enough for a front driver driven by me. And like I said, I sure do like my powertain warranty!!

[nue]

Speaking of which, did you get that little stumble of yours resolved?

[SpoolinWagon08]

Okay... I was driving my car today and getting on the freeway, in RPM's higher than 4k, under WOT... engine power cut out, knocked 6.8, air/fuel ratio went to 8.1?!? and now my engine is chattering like the video on the first page. It's just a matter of time now. I hope I make it home tonight to swap my mods tomorrow. Ugh...


Mods: MS-CAI with air flow straightener, BOV, Access Port with stock 91 octane 1.07 tune, (was planning on getting pro-tuned this month) and ETS TMIC.

FML.

either Severe knock retard/ecu limp mode.....or you bent a rod......is it smoking a lot w/ white smoke?

[SpoolinWagon08]

No smoke while idle. I just went out to run it for a bit and the chatter sound is gone! I don't get it... Idles fine...

[holeinmypocket]

sounds like you prolly had detonated and then your ecu went into limp mode....it has happened to me twice before i blew

[manofhonor24]

i bought a used MS6 and during the test drive the car performed perfectly. On the way home, not even 3 miles from the dealership my motor blows. #3 rod blew a hole in the engine. When the dealership towed it to the nearest mazdaspeed dealership, mazda said they never saw anything like it. That leads me to believe that whoever had the car before me, did something to it for sure and traded it in before it blew on them. it was a 2006 MS6 with 27k. I had two months left on the warranty, and mazda replaced the engine, transmission, and turbo all under warranty. All I had to do was pick the car up when they were done.

Now I checked on them and chatted up the technician that actually worked on the car, and he seemed to be a really upfront honorable guy. I would recommend talking to the mechanics down there and get a feel for the guy that will be working on your car. Now i live in Savannah, and there happens to be a mazdaspeed dealership 90 seconds from my house and one in Hilton Head, SC. I don't go to the one in Savannah because they are shady, while the other 30 miles away is more reputable.

Just my 2 cents...

[SpoolinWagon08]

Good shit. Well hopefully it will give me time to go back to stock. I re-flashed the ecu before i restarted the engine, so you're probably right.

[Lex]

Problem is detonation ... I found the ETS to allow the turbo to spool a little too well and spike. If it's heatsoaked that can cause some nice knock.

If you have an AP and are detonating, tune down the boost spikes and pull some advance from the intake cam.

SpoolinWagon08, what PSI were you spiking to and was the car heatsoaked or were you cruising for a while before it happened?

Car was barely on 5 minutes and I was cruising around fast paced roads so heat soak wasn't too bad.(96-115 degrees boost temp) I've been spiking bad lately, hence why I had the stock mode OTS 1.07 map running. Still spiking 19.6 on a regular basis, seen over 20 a few times with various stage 1 maps. My boost holds around 15, which is on the lower side thanks to my TMIC. If only I waited to gas it after my pro-tune.

I also have SU boost tubes, if that helps explain anything...

Thanks Lex.

Not yet. Dealer won't do anything until it throws a code.

You're wrong, there are already several 2010's fully bolted on here with no problems.

time for a new set of plugs

what Genpus are running BT i want to see links...i don't mean PTP or BNR or Reworked K04s

[Amazon]

You simply said fully bolted or BT. I'm sure it's only a matter of time before someone goes with a bigger turbo on a 2010. Pharoh is already fully bolted and tuned on SB, he's had no problems. A 2010 Speed3 has yet to blow, I'm sure one will eventually, but they've already established a much better record than the gen 1, been out for about a year and still has a clean track record.

I've been building a spreadsheet of the blown motors, using this thread, and what research I can do on other forums in the community. So far, I haven't found a single 2010 with a blown motor. Doesn't mean there isn't one out there, just that I haven't found it yet.

And fridgelips is the FIRST 2009 on the list. I'd say "congrats," but I don't think it's that kind of an achievement.

[Amazon]

Rods in the 2010 are said to weigh a little more than gen 1 rods, so perhaps they're a little stronger, but no one really seems to know for certain.

[Lex]

I think the biggest difference between gen 1 and gen 2 is the calibration and ECU.

[Amazon]

And the smile

[Stealth01]

Maybe that's why it's smiling so much.

[SpoolinWagon08]

Car made it home last night, running fine after the stock mode re-flash. One thing I noticed though, my clutch feels different, and seems to engage later than it did. Could just be placebo.

Not sure what to do at this point. bent rod?

[Lex]

If the clutch pulsates its a bent rod.

[SpoolinWagon08]

Slight vibrations/pulsing. Ugh.

I'm getting an 04 Tacoma. Sick of worrying.

[Lex]

Stop driving the car now. Don't even turn it on.

[Stealth01]

Yep, turn it off, take off mods, take to dealer. Oh, and gather your oil change receipts.

[SpoolinWagon08]

Originally Posted by Lex Stop driving the car now. Don't even turn it on.

Will be stock in a couple hours. Hitting up the dealer first thing tomorrow.

So should I put the blame on the the TMIC and mods, or just the motor in general? I will be telling the dealer I was just cruising on the freeway, car bogged, then made chattering sounds I soon noticed as I got off the freeway.

[Lex]

Don't mention any mods to dealer at all. Make sure they take it out for a drive and explain the issue and your concern. Keep on bugging them because the car is going to blow and if they are in it, they can't say anything about it.

The problem is it detonated and bent a rod. There could be many reasons.

[SpoolinWagon08]

So you can probably add my car to the list(s) soon.

Pending bent rod due to boost spikes + detonation.

-2008 MS3
-Mods: ETS 3.25" TMIC, SU boost tubes, Cobb inlet, Cobb AP, MS-CAI, Turbosmart BOV
-AP running stock mode OTS 1.07 map
-Incident at 70 degrees ambient and 96 boost temp.

What'd the dealer say when you dropped it off?
