Blown Motors

[Dragon Queen]

I am suprised that there have been hardly any Blown Motor threads on here....There must be a small representation of MS6 vehicles on this forum.

 

[chriscecc914]

why are the other forums showing alot of blown motors on the ms6? I only know of 2 on this site. me being one of them.

 

[laloosh]

go to the other mazda6 forums. I can count 5 in the past month. The ms6's are blowing left and right for some reason.

I have lurked over at the other board, and I have seen blown motors but My question is why have they not been posted here too?

Maybe those folks are not members here.

No offense intended to anyone on this forum, but while the focus of the two forums is very similar, the execution is quite different. I simply do not see a lot of 6club (can I even type that) members equally active on both. I think this is true of the members here as well.
Things here seem to be of a more aggressive nature: like a prominent member here flaming a post about a fuel pump, when he felt his shop (who sponsors him) was not getting the credit it deserved. While the facts of his argument may very well be true - the nature in which he presented his argument, caught him some flack over there (shocking).
Not a criticism, just an observation.

what is cuaseing the motors to blow?

 

[Dragon Queen]

Well from what I gather Rods are failing....

It's just Misrepresentation and it's sad. This is mazda24/7 not just dedicated to Mazda3's, Mazdaspeed3's or Proteges....

its simple and although people might get offended but the fact of the matter remains... TUNING! tuning is not an easy thing to do infact it is fairly difficuly especially if you don't know the limits of your car. not to many people know to much about this engine (MZR) not to mention the DISI and the CRAZY compression ratio. if you think you can put a huge turbo on and even if you run normal boost s*** will still happen b/c of the volume of air flowing and that is just one example now i am not sure what people are doing with these cars when they are putting on these huge turbos or even turning up the boost. all i know is that before i raise boost or swap turbos or even mess with the ECU for that matter i am going to wait a little bit to do some more research.

In my reading, it appears that more motors have blown without the ATP turbos than have blown with the bigger turbo.

Blown Motor at 20000 miles

Ladies and gentlemen i am sorry to report that my motor just blew up!!!
I was driving on the highway doing a steady 80mph (in other words no load) and blew a rod straight through the cylinder wall. I contacted mazda and they denied my waranty because i replaced the last cat on the exhaust system (bs right?!?!). Anyway mazda wants $10000 for the motor and $2000 for labor. Considering thats a third of the original value of the car i refuse to pay that.
My question: to all of you are:
1) Does anyone selling a crate motor for the MS6?
2) What would be the most cost efective way of getting this car back on the road?
Any sugestions would be greately apreciated guys. I baby my car and have done only minor mods: rear motor mount, cp-e intake, cp-e cat back and greddy boost controller which i actually used to take the boost level from 15.5 to 13 flat just because the car felt too jerky in city traffic. This car has never even been redlined much less run at the track.

Look foreward to any input and thanks in advance.

what did you replace the last cat with a test pipe?

 

[2.0t03speed]

and your best bet would be ken at protege garage for the fully built short block.

so you managed to lower boost with a boost controller?
you also said you have a i/cat back exhuast but got denied warranty for not haveing a cat? ummm

I love hearing all these i was cruising and it blew stories, i just find them wierd and full of s***.

 

[JoseProte83]

didn't he had 20,000 miles back in August?

 

[laloosh]

Ok so I have 20000 miles on my MS6 and so far I love the car. Recently however the car has been over-boosting like crazy!!! I was on the turnpike when it first time it happened and I noticed the boost went from my normal boost setting of 110Kpa (15.9 psi) to like 180Kpa (26.1 psi).
Keep in mind I have several mods to my car. Those I think might be relevant to the problem are: HKS blow off valve, HKS electronic boost controller and maybe the cpe intake.
Since I first experienced the problem I have re-done all the vacuum lines twice and replaced the HKS boost controller for a Greddy B-spec II because after I replaced the lines and seeing it didnt help I assumed it was the solenoid to the boost controller. Since I replaced the solenoid the boost hasnt peaked to the extreme of with the HKS unit but I also have been reluctant to increase the gain on the controller past about 20%. Even with this though I am seeing irregular pressure, normally it will be about 13psi but under some conditions it will spike to around 15.6psi.
Today I ordered the vacuum chamber (which sits below the intercooler and attached to the top of the intake manifold) the solenoid which is housed inside the chamber and the fuel pressure regulator as I think I might have I vacuum leak from one of these.
Any input on this matter will be greatly appreciated. Any theories or ideas as to what I might want to check next? I am especially interested in whether it is even possible for the turbo in the MS6 to develop 26psi even for a short time.
Also I am sorry if I posted in the wrong place but I am not very familiar with this forum and truly I am at my wits end trying to figure this out.

it had 20k 3 months ago and it still does. also 13psi tuns in 26psi.....hmm once again the bulls*** piles up

 

[2.0t03speed]

wow 26psi

 

[2.0t03speed]

double the boost with only a cai, and cat-back with no ems and thats proabbly what did most of the damage to your motor. im pretty sure as soon as they saw the profec they denied your claim well at least i would have.

 

[Dr. D]

26psi = BOOM!!!
