Just bought my first rotory. An 09' RX8 R3. bI'm not however a newbie to Mazdas. In the past I've bought and built an 03' Mazdaspeed Protege, an 08' Mazdaspeed 3, and an 05' Mazdaspeed Miata(my pride and joy! 333 whp! I have a few questions though. 1 will 19x9's w/+40mm offset fit the front and 19x10 w/+40mm offset fit the rear? Also, I like keeping things in house. Does anyone know if the front and rear brakes from a Speed 3 will fit our cars? They are much bigger and much better than our 8's. And last but not least, has anyone been running a DEPENDABLE 400 whp Turbo kit/set up? If so, how long, and some info and links would be much appreciated! The R3 is the best handling car I have ever driven! Stock it corners about as well as my fully modified Speed Miata. And I promise you that means something! Thank you all, and long live the Flying M!!!

can you write that again adding some paragraphs, punctuation and with the right grammar?
Then learn how to spell rotary and post again, thanks!

edit: oh, i forgot to add: search!

What makes you say the MS3 brakes are larger and better than the RX8s? They are not.

With all the necessary answers already given towards your post, please fill us in on your MSP, MS3, and MSM.

wow you guys are harsh lol

The rims should fit. You will need to roll and maybe pull your fenders in the rear.
And ive driven a 1 month old mazdaspeed 3 and the brakes are not better than the 8. And they didnt look bigger to me. Yes post pics of your other cars.

If the renesis could be dependably turbo'd to 400 whp Mazda would have brought out a Turbo version putting a Turbo on a motor not designed for a Turbo is never dependable. If you want 400 whp mod an evo or sti. I don't know how dependable a 20b motor is or the power it cranks out but I'd go there before I Turbo. If I'm not mistaken a 20b goes for 12 grand??

Not that no one has ever topped 400 on a Renesis before though...

Comparing shapes and dimensions between calipers, I am willing to venture and say no; they are most likely not compatible.

Please explain how you reached this conclusion???

Come on Chris!
You have to admit that the first iteration of your kits (the ones with the very low wastegate and chinese turbo) were not the best when it came to reliablity.
Now that you moved on to better wastegates and brand turbos the only problem i see is the choice of PCM. Your kit gives very good number and at that power level i think that something more dependable would be nice, maybe as an option.

The first thing is a fact, there have been reports in the past that can be searched for here. The second paragraph expresses my personal view on your actual kit so it's just my arseh... err opinion

blazenblue63

I'm sure there are some who have but reliably? No engine rebuilds over lets say 150k miles? I'm sure if you put enough money into it you can almost make any whp number. But to also make it last the lifespan of an engine normally would I find that hard to believe. Which is what OP asked for.

"Dependable 400whp" is subjective.

EsmerilRacing

Like all products, they go through a growth process, our has done so too. Regardless, our kit has done what it was set out to do and that is that. Some people like it and others dont and that is how this works.

What I don't understand is where the conclusion that our turbo kit will "eat out your engine" came from. I would like an example where our turbo kit ruined someones reliability? or where the parts failed without being abused? We have had to replace one turbo in 5 years of production that was faulty out of the box and the individual wanted a replacement, we did it with no questions asked. Other than that, none of the wastegates have failed and none of other components have either. Our ECU option, which is now setup 100% in house, is not a problem. The fact that everyone wants to use the Cobb doesn't mean that the Microtech, which on every other Rotary forum is used succesfully to generate alot more power reliably than anyone on this forum has attained, is a bad option. Its just not the "koolaid" that everyone wants to drink but it does the job and I have not tuned one car that has failed to date. Of course if you don't follow instructions to the "T" and choose to experiment or go through a learning experience with your car then things can happen with any kit and this has nothing to do with ours.

A turbo system does not eat your engine...as a matter of fact, it doesn't make it wear out any faster than the engine does on its own. The only thing a turbo can and does do is put more strain on certain mechanical engine parts, strain does not equal wear. A turbo can break your engine if the tuning is not right. However, having a turbo on your car will not wear the engine out faster, in fact it has nothing to do with that. That is why I asked about his conclusion. If you are boosting 40psi plus on a race engine its different because parts are deflecting in ways they shouldn't and rubbing in ways they shouldn't but this is not the case on a street turbocharged 8.

All I was looking to know is if it was a personal experience or just a conclusion reached without evidence. if it was from personal experience my next reaction would be "how can I help you with your situation", if not then that would've been the end of it.

Best regards,

Chris

You're right when you state that every product goes through some development even after the first final product is released.
I personally think that the problem, in your case, was the extremely bad timing you had when you shut down forum communications. It happened shortly after you upgraded to real turbos.
You have to admit that it wasn't the best combination of events in the world, not that it was your fault though. I understand that the automotive part of the business is possibly done just for fun, given what other fields you're involved in

While i'm still not fond of the pcm choice i'm sure that the new bunch of owners your kit will attract will serve as a better benchmark than the kind of troubled first release you had.
