Took it to the dealer today and had the RX8 technician drive with me. He said there is a signifcant loss of power from a stop in first gear. Wants to give a compression test to it....did say the engine might need to be replaced. He said the 2004 4 speeds autos have less acceleration power than the newer 6 speed autos. But this was a real dog compared to others 4 speed autos. Will keep you posted.....
 
Also, any tech out there for Mazda...what is the chance if they have to replace the engine that they put a 6 speed auto in rather than a 4? Is that even possible or does alot of other "stuff" have to change on the vehicle as well (just asking, I am not an "auto knowledgable person".

They will not swap your 4spd with a 6spd. they may fix your existing issues but they aren't going to retrofit the car to another build.

If it's an automatic, it might be that the parts controlling the torque converter are bad and it is permanently engaged/locked up.

If you haven't heard, ALL 2004, 2005, 2006, 2007 and 2008 RX-8s now have a 8 year/100,000 mile warranty on the Rotary Engine (housing and core), whether bought new or used, or in the U.S. of Canada.
 
Mazda steps up to the plate and shows customer support once again. If you paid for past repairs that PREVIOUSLY out of warranty, you will be reimbursed for covered claims.

Went down that path with a 6-spd auto. I ended up needing a new engine. Hopefully whatever the outcome, you'll be happy.

What's you driving environment like, lots of stop and go or lots of highway? Do you stay in manual mode mostly or full auto. What part of the country? Do you take lots of trips in the summer heat? Do you rev past 5000RPM in first on a regular basis?

Mix of highway and city. I would say most likely I have it in auto mode, but I put it manual mode here and there. Most likely I do this when getting onto the highway. I am located in Wisconsin, and do not take alot of long trips in heat. The longest in summer would be about 1-1.5 hours on the highway. When I do enter the highway in manual mode, I will get to the 7,000RPM level in 1st and close to it in second. I have done that in the city as well with manaul mode where I will run it higher RPM's

I'm Luvin' It by rotary

'04 model year with an auto tranny in hot climates is where compression problems are most prevalent w/8s.
 
Auto transmission models have only one oil cooler which is not enough. Rotary produces lots of heat. It's inherent to the design.
 
Manual models have dual oil coolers, and this helps keep things tame under the hood in hot climate, stop and go driving.
 
At any rate, the 100,000 mile/8 Year Warranty offered by Mazda on all 2004-2008 RX-8s, whether bought new or used, and even reimbursing owners for core/housing problems when they were formerly out of warranty is a class act.
 
One other thing, the new Renesis has a third fuel metering pump, whereas the last gen only had two.
 
I love Mazda for keeping the rotary alive and well. It is unique, and while it has some negative aspects such as low torque and poor fuel economy (although I just broke 22 mpg on mixed driving for the first time, which isn't terrible for sports car), it has redeeming qualities in spades - especially that 9,500 redline that just makes beautiful music, while helping to keep the weight way, way down.
 
My 8's handling is nothing short of amazing. And the braking is phenomenal too.
 
I love this car more each year.

Got a call from the dealer today. After compression tests and other tests sent to Mazda, Mazda will replace the engine. At least they stand behind their product. Will keep you posted on what it is like when I get it back...
 
Question - how does the warranty now work on the new engine? Does the warranty start over for the engine only? Or does it continue from where I am now?

I'm not sure. Ask you service rep.
 
Sorry.
