Just had the car fixed by the dealership too.
If you are able to take the battery out, take it to AutoZone or some other parts place and get it tested for free.
*EDIT* Be sure your terminals are clean and tight.

Sounds like either a weak battery or failing battery connections.

At a guess, I would think that the RX-8 has 4 turbos from the factory. Im not sure though. There might be 6. I think 2 is too few?

Yea I think you're right, because it does kind of seem a little bit stupid to only have 2...

Someone in your area may have a comp tester, that's usually cheaper.

Just be sure it is a rotary-specific compression test. Ordinary compression testers won't give you the full data you need. Yes you can call up a Mazda dealer and schedule the test.

I think RIWWP is right on the money with 6, 1 per rotor face.

No, it has a "b" in it so exponential win must be applied... I believe it has 42.... Please confirm RIWWP

42 is always the answer to life, the universe, and everything.

Can't go wrong with 42.

When you say failing connections you mean one of the fuses?

No, battery terminal connections.

This picture is pretty obvious, but the corrosion can exist out of sight between the clamps and the posts, needs disconnecting both to clean clamps and posts thoroughly, then correct and proper re-seating when reconnecting.

Hour and a half to go...

Here's a dumb question..

If you switch on the air condition right after you start the engine.. will it hurt the engine?
(Assuming cold start)

If so, why?

Thanks!

Do i really need an upgraded ignition system to run water injection? I can understand that too much water will make the mixture harder to ignite.

Thanks!
