Well, I joined a dubious club. I was driving my car last Friday pretty normally, and merging onto the 5 from the 134 around 5500 RPM and my car started sounding like a truck, EGT's spiked, no power, and CEL light started blinking. Got it towed to the dealer. Found out yesterday it was indeed a blown motor. I'm bummed. Engine lasted about 20,000 miles on the turbo kit. Have to get a new motor. High probability apex seals tore through the turbo. Turning back to NA anyways.

 

sorry man

 

Wow. Sorry to hear that. Any idea what happened?

 

Ouch, sorry to hear.

 

Pretty damn sad... I was about to buy greddy + int x and now i'm not sure it's a good idea..

 

Not sure. We tuned the daylights out of this. Never tracked/1/4 miled it. I'm not using this as an excuse, but I have an 04' and I got a notice about 3 months ago that extended my warranty, but unfortunately I gave them a great excuse to void my warranty. I guess they had some design flaws with the 04's that might have only exacerbated the problems. Some people on here blew their engine/turbos shortly after they got the kit. Some people have 20,000+ miles on their car with no problems. Can't tell you why. No rhyme or reason.

I was only running 6.5 psi of boost, as I had a flawed wastegate spring on the Greddy turbo that only allowed me to boost to stock levels. We were getting ready to install another spring to up the boost. Won't need that anymore.

 

whats up with the 04 (as I have one)??

Why did they / how did they extend the warranty?

Please give all info possible

PS sorry to hear about your engine

 

Sorry to hear about your engine fanman. cali style, did you get the recall notice?

 

That sucks... I'm guessing you didnt have the recall done, but would it of mattered?
How many miles were on your motor before the turbo?

I still dont understand how people are ready to blow 10k on these new (untunned)turbo kits that put out wayy more CFM then it took to blow your motor, with out knowing what the cause is or how to prevent it.
Atleast as they keep blowing up one day someone might find the weak link.

 

Fanman, sorry to hear that. I guess your opinion of GReddy isn't going to be going up after this mishap either.

You had the emanage blue though, not the int-x or EMU, right?

 

Can anyone say for sure what the differences are between '04 and '05?

What exactly changed in design/production? If anything.

 

Sorry to hear about that Fanman. Please keep up apprised of what you find out.

I don't think cali gets a recall being that I take it he's not in North America.

 

no im in the UK where they do things diferent (which often means not giving a crap about the customer unfortunately)

What did the recall etc do?

What was mazdas statement about the engine troubles?

 

I lost my engine ( the car is NA) a year ago August. I got the truck sound. I never got an explaination of what went bad. There was no apparent loss of power. When my RX7 lost a apex seal, I lost power. But there was no change in the noise level of the engine.

 

Since you're paying out of pocket anyway - why not get an extra rotor while you're at it?

^ because theres a lot more involved than just dropping in a 3 rotor. The expense is going to be 2-3x more.

 

sell that greddy garbage and get the mazsport kit....

 

seriously, will some1 tell me more about these engine problems and what mazda said?

 

The issues were mostly related to the OMP (oil metering pump) not injecting enough oil for sealing purposes into the engine under certain loads and at certain rpms. To remedy this, Mazda is reflashing the PCMs to inject more oil.

Under this, Mazda is checking for bad cat converters, fouled plugs, etc...in a few cases, like less than 1%, some people will have their engines replaced.

There is no difference between an '04, '05 or '06 engine.

 

You're kidding yourself...

 

why...greddy is garbage....It's been proven

 

people often forget that you get what you pay for. It's known that the greddy kit was rushed out the door with many bugs. And its not surprising that on the very early RX8s, with a very early turbo system there was going to be some big booms.

There is always a risk with Forced induction - I'm staying N/A right now till i save up a good amount of "emergency car money" and not to mention the 8K for Mazsports Kit.

But time/money/reliability/performance are all tradeoffs against each other. I'm making a general assumption but the reason Mazsport's kit is so ******* expensive is because its good high quality tested stuff, and the reason it took forever for Mazsports' to come out is beacuse it had to go thru some insane testing and realiability stuff.

 

Yeah more cause people weren't getting the numbers they wanted and the ecu wasn't so great. Greddy didn't blow his motor, from the sounds of it FI on a weak motor did it. So it wouldn't matter what kit he had on the car.
The greddy would of blown the motor right away, not 20k miles later.

 

The only part of a turbo kit that you can blame for blowing the engine is the EMS - either it wasn't tuned correctly, or it malfunctioned. You can't blame the poor quality couplers, the turbine, the intercooler or the piping. IIRC, FanMan is running the IntX right now. Not that it was the fault of the IntX. My bet would be something similar to what I believe happened to me. He probably pinged at some point in the tuning process and cracked a seal at that time. The seal might have finally just given out. Unfortuantely, there is no way to know for sure.

One thing is for sure - if FanMan is running a good EMS with a good tune, which I believe he was, then dumping the pipes, couplers, IC and turbine is NOT going to buy him any additional reliability. Now, I have no doubt that the couplers that MazSport sells are top notch. I'm also sure that more effort was paid to sizing the turbo to match well with the Renesis. That's all well and good, and worth some extra $. But, saying that you are buying additional reliability is fooling yourself. Is my GReddy turbo setup using the IntX any more likely to blow my engine than MazSport's setup using the IntX? I think not.

 

Guys, stop hijacking the **** out of this thread with questions about recalls, differences in 04 and 05's and arguing about mazsport vs greddy.
/end rant (madog excluded since his post was informational)

Fanman, that sucks about your car!! What's the game plan now? Rebuild it and stay NA or are you going to go back to FI? Car still at the dealership?
