MazdaSpeed 2.3L DISI Turbo Blown Engine Resource Thread

BTW, I am a power engineer and have a good job with great pay. If i felt like wasting my money (maybe something you enjoy) then I would have decided to pay for my own engine before letting Mazda deny my warranty. Perhaps, sir, you are a tool.

I applaud you for fighting and wish you luck with your car. But, if your case had to go to court, it would have more than likely gone Mazda's way if the mods involved raised the boost levels beyond what the car came with. And that wouldn't be hard for Mazda to prove.

Supposedly stock cars have blown but given the amount of these cars produced around the world, had this been a regular occurrence, there would more than likely have been a class suit against Mazda regarding the engine. So far I haven't heard anything (not that there isn't one in the making).

You're luckier than you think. Unless you can produce ample evidence that the motor has a defect, it's an open and shut case for Mazda (imo).

Still waiting for my car...

To be honest, I am just getting worn down. Unfortunately, the times I think about the car most often is when I am sitting in front of a computer. This thread just so happened to be close by for my outburst.

I am lucky to have gotten my car fixed and I will most likely pay for the aftermarket part removal and installation. The furthest I will go will be to ask for a reduction which I did today. I was told by the dealership staff that they will reduce the labor time they charge for which is great.

I miss hitting boost

[Speed I]

first off i abused my car every day im lucky it lasted this long mazda warranteed about $14,000 in parts through extended and factory warranty. fuel pumps axles differntials and basically anything you can name but they did not warranty my new motor so i wnet all out on the new setup. i had 80,000 miles traveling 135 mph shifted from 5th gear heard pop and then a cylinder misfire occured in cylinder 3 thats all she wrote.shot a hole in the cylinder the technician said the pump leaned out or when i ran syntheic oil the car ate it up so for a recomendation synthetic should not be ran in any disi motor we blow it out i have seen another motor lock up and he used syntheic oil every time he came in at regular intervals and had no oil left in the motor. the current setup was hks twin igniton controller, stock plugs, cobb stage 2 map,cp-e downpipe, corksport tbe, injen cold air intake, apexi super grounding system, stock fuel pump, stock top mount, a ton of suspension work, bsd, oil pan baffle, dynoed the car at 280 whp 312 wtq before it blew up. for current set up check out the profile. bigger and better things are coming in the future.

I find it hard to believe that its the fault of synthetic oil. Synthetic oil is superior to dino oil especially when it comes to its ability to withstand heat. I would say running synthetic oil after break in would actually help with wear/tear on these motors especially.

Furthermore there are other direct injenction motors out there running synthetic oil with no issues.

This makes you one of the first reported people to blow with the BSD.

Did you have water or meth injection by any chance?

so you had an hks twin power and an apexi super grounding?
you had a cpe dp but a corksport tbe?

stock fp also which isnt good

[Speed I]

no i was not running methanol i blew the motor so now im building it and changing up the whole setup i got rid of the cobb crap and learned that cp-e is easier to tune with i blew my motor because cobb doesnt say you need a fuel pump to run any of the tunes so when i leaned out nothing could help i had no problems at all the whole time i had the bsd on for three weeks and after that last part the motor went im not sayomg it was the bsd but cobb sucks.

[cld12pk2go]

So were you showing dropping fuel pressure under boost?

[802MS3]

lol another right after the BSD was done

[Speed I]

no i wasnt at all i had no problems before with fuel pressure dropping and right when i shifted into 6th and got back on the throttle the popping occured and then misfire came up and i drove home on two cylinders. the only thing i can think of is the fuel pressure did drop and leaned out and then detonation happened and blew a hole in cyliinder three but the top of the piston melted to the cylinder wall which is like the spark plug got to hot and melted because the spark plug in cylinder one shot off which was suprising since the hole was in three i had fulll compression in the fourth cylinder and the rest were 120 for cylinder 1 and cylinder 2 and three both had around 40 psi if that helps any

[MS3BOOSTIN]

another blown motor for this week i tried everything to prevent this from happening (BSD,METH,TUNING)just to name a few!!!!!!!!!!!!!!

[2007speed3]

^^ how many miles? how did it happen?

[MS3BOOSTIN]

It had aroung 14k miles 1st gear around 4k rpm kaboom!!!!!!!!!!!

[DaleNixon]

Can you elaborate on your mods/tune/etc.?

[Smoke_31]

So, I picked up my car yesterday from the dealership.

A couple small things I will have to go back to the dealership about (broken battery box cover, cracked tweeter grill, let them know they did not tighten down my starter 12v+ wire on the battery, random yellow wire running directly over turbo where it will melt, etc.) but other than that, it feels good to have it back.

As for the 4 hours labor, I spoke to the service manager and explained my thoughts. He said he would charge me the internal labor cost which is $85/hour rather than the regular $110/hour. I said great, sounds fair.

When I went to pay, the girls at the service desk said "We didn't hear him say $85/hour so we'll charge you $68/hour". They did hear what the manager said, but it pays off to be sexy . Kidding aside, I thought that was pretty fair.

[Lex]

Can a mod please update the list on the 1st page?

[mleblond]

Yeah I'm on my second engine. Mazda replaced engine AND turbo under warranty.

New engine knocks every other day between 3-9 degrees. Car is 100% stock now.

I had 60k kms on the engine. Cylinder #4 ceased and did a window in the front of the block taking the starter with it, was in part throttle 3rd gear. Final bill 12,500$.

Thanks Mazda for paying the bill, not sure if they would pay again on my next visit....I guess after 40k more km they couldnt care less.

[car46999]

I read this post from time to time, I have some suggestions for everyone.

STOP CRAPPING UP THIS THREAD. What was a resource thread is now 11 pages of BS.

Would a moderator please delete all non "I blew my engine posts" (to include my post here)
Also I would suggest locking the thread, and a moderator take PM's of new blown engines, then post the FULL info up.

One more thing, anyone that says "well stock cars blow to" is a f-tard. If you personally have one then I feel for you. Otherwise stfu.

If you read the second post, listing the blown motors, you’ll see that there are at least four (including mine) with stock motors and a few more where the only mod is the MS CAI. That Mazda endorsed mod is pretty darn close to stock.

There is a lot of good resource info here, you just have to be able to read it. So what is your point?

[ASIC_BSEE]

When this happenned, did you see any smoke come out the exhaust? Blue/grey smoke possibly?

[Smoke_31]

The car had no smoking issues before it blew up. The car now has smoking issues due to the stock turbo seals haha. If it's not one thing, it's another. Off to Mazda tomorrow for a new turbo hopefully.

[_Toxic_]

I know a guy who blow his engine.. he was in 6th gear shift to 4th, doing about 55mph full throttle, reached 75mph, boom! Was a hole in the engine block, and cracks arond #1 cylinder house... The only mods he had was catbacksystem..
Year of the car was -06 and has gone about 5000miles, Iam from sweden.. dont know what that is in yours miles... think it is like 3000... not much anyway.. And Mazda fixed it on the warrenty.... think he got a new engine..

[kotez]

Has octane rating of fuel used been taken into account in these cases? Sorry if it has been talked about, don't feel like reading all the pages.

Can we really count the oil starvation cases?

[spool]

Car; 2007 Mazdaspeed 3 23000ish miles
Cylinder; probably 2
Damage; blew a hole through the block
RPM;5100~
Mods; TurboXs FMIC, Cobb SRI/TIP, Greddy Type-S, AEM UEGO and TRU-BOOST, Street Unit TP, Stock cat-back with removed resonators, PT-Performance Trans Mount
Exhaust Manifold; Stock
Situation; Pulling out to catch up with traffic in 2nd, got on it and the car took off as usual and then boom, smoke and quiet motor. So I just coasted to the nearest side street and pulled off of the main road. My boost controller is set at 16.5 psi.
Warranty; probably not, won't know for a couple of days
Oil; Castrol Edge Synthetic 5w-30

Just to cover the basics: No BSD, No Tune, No Meth correct? Tks

[boardjnky4]

you turned up your boost and your didn't tune for it?

come one now, that is hardly any fault of the manufacturer. with that many mods, you need a custom tune

[spool]

Who said anything about the manufacturer being at fault?

Anyway, yeah I hadn't gotten around to the BSD yet and the tune was set up to happen on Wed.

question, where you going wot when this happened? and no fp?

[jwdp54]

imo even if your stock, a dashhawk should be a priority if you buy this car. it is honestly my favorite piece of the car because without it i wouldn't know what is going on with the car.

[bhstall]

engine blew at 10000 miles.....got new engine from mazda.....blew again 13000 miles bone stock......... traded it for a cx-9.....lots parts for sale cp-e standback2, standback2 software, and pnp harness....cobb turbo inlet.....possibly my dashhawk....rks bov...pm me

Anyone see the conflict in that post.

"Blew bone stock."

"Parts for sale: standback2, standback2 software, and pnp harness....cobb turbo inlet.....possibly my dashhawk....rks bov"

I say Standback Tuning FAIL

[chrismia]

just brought my car in for service and the manager is pretty cool.

i asked about putting an sri in and if it would be a problem.

he said hell no, just don't put a BOV in. that there were 2 cars in the back with blown engines and that they won't honor the warranty. the big issue was that they couldn't produce any paperwork that they had service done with their car. no receipts, nothing.

i don't know how or why the BOV becomes the deal breaker with the warranty, but i just wanted to share my conversation with you.

thanks

[bhstall]

the first blow did happen with the standback, down pipe testpipe, cpe flash on ecu,cobb turbo inlet, aem intake. bent #4 rod at 10000 miles.....they replaced the engine under thier good will policy.....not under warranty.....and under the warning they would not replace it agian.....they did it under good will policy because they found that the # 4 injector definitly stuck causing the # rod to bend.....with the second engine blew with no aftermarket parts including the standback....the ecu was flashed back stock.....I wasnt going to chance that i somehow caused the injector to stick.....didnt matter same #4 rod bent again at 13000...however they already had taken my drivetrain warranty...they recommended trading it in on something else.....i did and took a beating.

[Lex]

Stuck injector hydrolock FTL. Chalk that up as another failure mode.

[Driver72]

This thread makes me REALLY nervous about getting a MazdaSpeed 3
How many engines have blown or whatever in these cars?
