A few general Question
Dear friends:
I own a six speed manual rx8 with 20k mileage and live in Pakistan. I recently blew my ignition coils.
As it turned out, the parts of rx8 here are very very expensive e.g. a set of igntion coils cost about 500 dollars. So i have decided to import these parts directly in order to save cost.
Furthermore, when i searched this forum i found out that ignition coils fail every 20k miles or so. I am sure that there are other parts which also have a fail cycle which i do not know about.
1.So can somebody kindly guide me to what are the most likely to fail parts in rx8. As of now i have identified the following parts to import:
2. Also can somebody tell me what is the life of stock tires in rx8 and when should i be looking to replace them.
3. While i was driving to workshop with blown engine coil, for some reason my cat got red hot and my mechanic told me that it had melted inside. As we don't have any emission standards in my country so the mechanic simply broke the cat messhing from inside. So can somebody tell me what performance/mileage difference are we looking at. Will i have to retune my car etc etc.(Please don't flame me for removing cat because i just cannot afford a new cat)
Kind Regards

Regarding the coils (and in fact a complete ignition solution with wires and plugs too), you may want to look into this thread: https://www.rx8club.com/series-i-aftermarket-performance-modifications-23/bhrs-ignition-system-offerings-145128/
That's what I'll do as soon I need new coils.

you can order new ignition coils for $100 at www.finishlineperformance.com
i dont know about shipping though. that might run you.
the mileage you get out of a tire depends on the tire. a sticky high performance summer tire wont last more than 30k miles. a crappy all season tire could last 80k miles. i have the toyo t1r, its a great summer tire. i got 26k miles out of my stock tires and they have 2/32th of tread. thats the minimum allowed in the usa. i did not run them all the way down as that is super dangerous.
the bhr ignition upgrade will actually probably be pretty useful for you. the only downside is that it will be $400, compared to $100+shipping for the OEM coils. however, the huge upside is that it uses GM Yukon coils, which should be pretty easy to obtain in your country. i'd check that out for sure.
knocking the cat out is fine, you probably picked up 10whp doing it as well. you wont have to retune the car. although, it would probably be a good idea. the cobb accessport (mazdamaniac edition) will let you do that. the stock computer dumps fuel on the cat to cool it down, so if you remove that you'll probably pick up a mpg or two.

Thankyou very much. After two days of waiting i got my answers
1. Can you please explain the above phenomenon in detail.
2. My mechanic has got a OBD-II compliant device but the guy is not much knowledgable. Cany you please tell me if it is possible to retune the car so that it doesn't dump fuel on cat.
3. What he has to do to accomplish that.
Thanks once again.

fuel is cold, the cat is hot. if you put cold liquid on a hot metal, it will cool down. thats all there is too it. because our engines run so hot the cat is always in danger of melting, so the mazda engineers decided that we have tons of fuel in the car and we can use some to spray on the cat to cool it down.
you need a cobb accessport to turn this "feature" off. contact mazdamaniac. www.mazdamaniac.com

i really suspect this statement that the mazda rx8 sprays fuel on the cat.....a petrol lights up at 60 degree celsius, so wouldn't it be better (and in fact safer) to spray the cat with water (or something which does not cost (in my case) 6 dollars a gallon)
Can anyone verify this statement and if some genius is mazda has indeed incorporated this spraying of fuel on cat in the engine design; so can somebody please tell me what can be done to stop it beside buying a 700 dollar equipment

You would have to contact MM and findout if the Cobb will work for you other wise you will need to use one of the flash systems available in Japan or a piggy back such as a Interceptor X.
Whoops, I missed the $700 remark - Can't happen unless your a computer genius. Cobb AP = $700.00, used Interceptor X = $1000.00, Japan flash = $1300.00 these are just estimates on pricing and all would be plus freight. Last time I tried to send something to Pakistan the import duty was more than the product.

Dont ruin threads with perfectly good discussion going on with sarcastic and racist comment.
Mods: Why do you allow this on your forums. Every time i post something some comes back with a "witty" comment about my name.

If you will read the service manual you will see that the EMS runs very rich mixtures to keep the cat cool and does not spray raw fuel into it. A copy of the complete service manual is available on this forum and free. You will need a flash to fix the mixture or an AP.
You would have to contact MM and findout if the Cobb will work for you other wise you will need to use one of the flash systems available in Japan or a piggy back such as a Interceptor X.

Can you please point me to a service bulletin where i can read about this.

the AP is the accessport, just abbreviated.
the EMS simple means engine management system. that can mean the stock PCM (powertrain control module) or a piggy back system like the interceptor-x.
the interceptor-x (int-x) is a piggy back EMS. you plug it into the cars computer and with it you can change the tuning.
the japan flash is a flash (im sure there are more than one) from a tuning company in japan. you send them your PCM (the cars computer) and they flash it and sent it back to you.

Thankyou....Can somebody point me to the right direction of a 05'service manual....i searched but there a zillion of them and i don't know which one is the latest.

The 04 and 05 service manuals are the same and to my knowledge only one version was printed. There have been many updates due to flashes but you stated yours was a Japan version so the US updates would not effect you. If for some reason you can't find the 04/05 service manual I would be happy to send you an email copy of it. See your PM box.

Wow. Even though the comment is no longer visible, thanks to one of the other mods, let me reiterate the fact that racism is NOT tolerated on this board, and is grounds for automatic and permanent banning.
