Let you know how mine runs when I get it back.

I'm not trying to be a wise ***, but do you know the technical reasoning behind this. i.e. what would be damaged and why? I drove according to the proper break in procedure, but when i bought my car "new" it had 96 miles on, which I figure is a lot of miles worth of test drives where people were probably on it pretty hard. just curious

That is why if the motor is broken in properlly you will see more power at 10K miles or 40K miles than you will see when new.
Sorta the opposite of a piston motor.

Dont know if this holds true to rotary engines but when i bought my bike i found this website which talks about breaking in an engine and how its actualy better to break it in hard. The site seems pretty convincing but again, He doesnt say anything about rotary engines so........

50K???
100k???
I expect to get 150-200K miles from a properly broken in non turbo 13B or 13B reni. with 2mm apex seals.

Mazda's Guidelines
The Mazda RX-8 Owners Manual lists the following information for the break-in period of a new vehicle:
"No special break-in is necessary, but a few precautions in the first 1000 KM (600 miles) may add to the performance, economy, and life of your Mazda.
- Don’t race the engine.
- Don’t maintain one constant speed for long.
- Don’t drive constantly at full-throttle or high engine RPM for extended periods of time.
- Avoid unnecessary hard stops.
- Avoid full-throttle starts."
A review of the Mazda RX-8 Service Manual Highlights revealed the following information regarding break-in:
"A fluorocarbon resin coating has been added to the trochoid surface (rotor housing) for improved initial break-in."
Racing Beat's Guidelines
The Mazda guidelines are reasonable and prudent. If you have any questions or uncertainly regarding the break-in period, we suggest you follow these official recommendations.
We receive many requests for our recommended break-in procedures. The following are Racing Beat's recommendations:
- For the first 1000 miles do not accelerate under full throttle.
- During the first 1000 miles do not exceed 4000 RPM.
- For miles 1000-2000, expand the RPM upwards - but do not accelerate at full throttle.
- Over 2000 miles, full throttle and high RPM is acceptable.
In summary, our guidelines offer a progessive method to increase the working loads placed on the engine.
Oil Change
The Mazda RX-8 Owners Manual indicates that the engine oil and oil filter be changed every six (6) months or every 7500 miles, whichever comes first. Racing Beat supports this recommendation.
Mazda recommends the use of SAE 5W/20 with a quality designation of ILSAC or SL.

That is what is so frustration about this car. When it is running right it is great, one of the finest cars I have owned but, when it has a problem many times Mazda dose not have the skills to fix it or dose not want to spend the money to find out what is wrong then fix it right.
If so many re manufactured engines are failing stop installing them. Spend the money, correct your mistakes and install new engines. Unfortunately Mazda cares more about saving money then satisfying their customer base. sounds like a great recipe to go out of business.

I just don't get it. Maybe my 2004 engine was one of the good ones and got screwed up through a Mazda service mandate. I see the Speed Source RX-8 ate up the field in Mexico at the Rolex and am very happly about that. Now give me an RX-8 that runs right. That's all I want.
