Blown Motors

Hey guys,
Do you think it could be the cruise control? I was wondering if maybe the CC cut fuel to slow speed and thus blew? Personally, I would never use CC if I had a turbo. Also, go with Ken about an engine, it's got to be cheaper and better build then stock from Mazda. I know how you feel and I hope you get your car up and running.

A LIE....A VERY BIG LIE

no way. mazda never lies. the rx8 makes 255hp like the first brochure said. the rods in DISI are forged like the article says. the flywheels are interchangable between all 2.3 engines like mazdausa.com says.
 
Talk to Mr.Tea on the other forum about that car. He's seen the car and spoken with the guy at his own place of business in person. It's no BS. Several people on the other forum have spoken with him, and he gives the same detailed list to everyone who has asked. On top of that, his face is kind of well known around the Mazdaspeed buildings and he has a high reputation. I wouldn't call BS until you get all the facts. I don't find it hard to believe at all, really. Ever seen Chevy's 200+mph Cobalt using mostly parts you can buy from Chevy? It was featured momentarily on a program on Speed (not the one from Street Tuner Challenge) being tested in the salt flats. Performance divisions of automotive manufacturers are paid to make selected models faster. That's thier job. It's what they do. Why wouldn't you think Mazdaspeed would take a crack at their highest bhp/btq vehicle they offer? It may not have been publicised, but that's probably because they didn't want to take any spotlight off their precious MS3.
 
The car should handle 25psi with a proper tune.

Supposedly the CEO or head or w/e of Mazdaspeed owns a Speed6, port injected, 500+awhp, stock block.

something tells me that it's going to require MUCH more than just a tune to handle enough boost to put down 500+ hp at the wheels. the car was made to ship with ~280hp at the crank, so to even THINK about putting close to 2x that amount down at the wheels would require an extensive rebuild of the powertrain internals including pistons, rods, intake, turbo, trannie, axle (oh god the poor axle...), exhaust, etc. hell, if i remember correctly, people are reluctant to even put slicks on the stock ms6 because actually putting down that much power has been known to cause axle trouble for its AWD.

no way. This car is falling apart on people running stock power. No way 500+hp would work out in stock form. I have an extensive rebuild and im hoping i can get enough fuel to hit those kinds of #'s

What???

The cruise control controls the throttle just like your right foot does and therefore will not damage the motor.

Regarding the fuel cut, it is normal for the injectors not to open when you are coasting. No fuel = no combustion = no problem.

lol...can you imagine if cutting fuel to slow down the car blew engines? everyone who's ever used engine braking to slow down would be constantly playing with fire! (rlaugh)
 
My engine just blew, 2004 6i, 51400 miles on it. 1,400 miles over warranty and the dealership is giving me a very hard time. Check out my post, I just made a post about this.

I am very pissed, considering we just purchased a Mazda3 from them this past June.

Contact your Mazda regional service rep. They will take care of this. If you still dont find resolution, contact the Mazda Arbitration Board and file a claim.

I had a similar issue on the 98 SVT Cobra. Rod bearing spun, car was out of warranty by 11,238 miles. Ford replaced my engine and gave me an additional 24,000 mile warranty on the new engine. I did have to pay a $500 deductable however, but that was a small price to pay considering the $8100 price tag of the replacement.
 
sadly i am aware of the article. it comes from the same corporate mouth pieces who say the flywheels are interchangable between the turbo and non turbo 2.3. it still says to date on mazdausa's website you can use "mazdaspeed motorsports" flywheels on either 2.3 which is 110% not true.

the rods have casting patterns and casting marks on them. the pistons are definetely not forged. thats why i posted the pictures in two threads comparing stock to aftermarket. the rod is made of the same material as one i chunked out of my FS 2.0, and those are also cast.



pm me or call me any time. you have my cell phone number :)

heres the post straight from ken who had disassembled and built the 2.3l mazdaspeed motors.

Ok.. thanks..

I called corporate this morning, since the service manager never called them back. I had to call the service manager late yesterday afternoon to remind him he has a voicemail that the corporation left. I was pissed that he is sitting on his ass..

When I called corp. again this morning they told me they now have the district and regional manager involved and within' 10 minutes I got a call from the dealership asking me to fax over all my receipts for my oil changes. Looking up the 2004 Mazda6 owner's manual there are two different schedules. One at 4 months/5,000 miles and one at 6 months/7,500 miles. Not sure why they have two on there.

The most I went between oil changes was 5400 miles, which I don't think would be a problem. Glad you got your ford fixed, I had a mustang as well under warranty and when they fixed the intake gasket, the dealership noticed the intake itself was messed up and fixed that for me.
