Thats funny, I plan on getting there for less than half of that... tell me I cant do it, it will just make it that much more of a victory when I do 
Inginuity and know how can save you a lot of money!
With enough money 400whp is attainable, there was a guy down in PuertoRico who was running just over 400whp for about 6 months till he decided he wanted morepower and went for a 20B build. From what Im told, once you cross the 400whp mark youre gunna have to startworrying about the differential, and possibly even the E-Shaft. Not to mention upgrade fuel and ignition, cooling, and one hell of a turbo.
Like everyone says, it can be done if your pockets are deep enough and if youre brave enough. 350whp is a much more reasonable goal which can be made without too much fuss, and if you ask me, its plenty of power for this car. Past that you can start going on a diet to make up for the last 50 horses.

I think it's funny how many people here think 400-rwhp ISN't possible. Of course it is, but it will take a lot of money.
Scott has hit over 370-rwhp, and I have it on a good source that's true. Scott WILL hit 400-rwhp soon. He's obviously not going to go public with it yet until he has the products he's going to offer to back it up.
To the OP: The RX-8 is a still new car with not nearly the aftermarket support of the S2000 or 350Z. Tuners are affraid of the Renesis rotary engine, and it hasn't been since recently we've gotten more people offering new stuff to make power. The ingition system is currently what is holding people back right now to 340-rwhp, and no one makes any viable ingition upgrades (save for a set of $650 Okada "Plasma" coils that haven't proven anything yet and a $500 HKS ingition amplifer that hasn't proven anything yet either). And you can't just dump aftermarket ignition coils in, like MSDs, because of the Renesis' unique crank angle sensor (among others) and uber-bitchy PCM.
But it WILL be figured out soon enough. I remember when people started tuning new FD's, and the power "cap" kept rising every year as people figured more stuff out and the aftermarket helped more. I think it will be the same for this car.
And I know you claimed to build 400-rwhp reliable 350Z's, but anything more than 450 and you might want to replace those paper mache connecting rods and do a whole engine rebuild for a lot of money.
And also, don't underestimate a 350-rwhp RX-8, in a car this light with handling this awesome, it will impress the hell out of you.

I wasn't talking about MazSports 370 number. I was talking in general about a 400 WHP (which I am not even sure they ever claimed publicly) I remember them saying that it is capable of it, but can't recall seeing anywhere that they actually did that.
It just so happened that the previous post came before I posted mine, so it looks like I am questioning Mazsport. By any means, I do not. And I apologize if it came out sounding this way.
Mac,
How the hell the place where I do my mods has to do with anything?

Mazsport does claim it publicly.

it says that the kit is good for up to 400. This means that the components included with the kit have enough capasity in them to provide for 400WHP.
Nowhere it says that RX8 equipped with the kit will put down 400WHP.
Unless someone comes up with an adequate ignition system, this number will not be reached no matter how big a turbo, fuel system and intercooler you may strap on the 8.

The 8 is a great car. If high hp is your goal, give it a few years or have deep pockets. But power is slowly coming up due to the effort of Scott at Mazsport. The z has the parts and fan base but its quite expensive to reach its potential too. S2k has potential to make alot too but it too is expensive and like the 8, is fairly maxed out from the factory. You will be paying for a few hp per mod unless you go with forced induction. Its possible but as with most things, you must pay to play.

Wow didn't think this would turn into an argument, but whatever. Thanks for everyones advise. I'm not wanting to do a motor swap, If the 8 hasn't made 400 yet I know it will. I'm not a rotary expert by any means but have talked with many that are, they are saying it can be done its just not very reliable yet.
Someone said if i want a 4 door get an evo or sti. I have an Evo 9 MR its all great and what not but way to plain. Mitsubishi isn't all that great of a company anyways, I have had nothing but problems with it so i just decided to build it from the ground up. Good to go now, I just want a new project to work on.
I'm not writing a check to anyone to do this for me. It's not hard to build a turbo kit. No reason for me to pay 3000-8000 for a kit when i can build one for half that price. I'm just wondering whats going to go wrong but I got my answers so thanks again for all your advise.

No matter how you cut it, unless you go all EBAY parts, youre gunna spend at least $3k turbocharging this car, even if you do all the work yourself. An INT-X alone is $1500... and youre looking at another $2k worth of parts on top of that at least.
Go for it though, its been done and can be done again!

thanks man for the word. I am far from knowing all about it. Just a fraction, but that is the great thing about this forum, when you ask a well defined question that, good people will always help with the answer. Some answers are great ad to the point, some are useless, but you sort through it, get what you need, ten go and do it and gain a point to your own experience

Yes potentially it can, no without the ignition upgrade it won't.
he problem here is no the turbo system, it is the fact that the stock coils can not provide strong enough pulse to properly ignite the mixture at the levels of around 350ish and above.

Oh Ive been paying attention.
Just not to you
No one has REALLY tried them yet have they? Therefore
But, if you know something why don't you just share it with us instead of hopelessly trying to pick on me. What is your problem anyway?

Turbo Kit, Type 1 - $7995.00
MAZSPORT'S "Type 1" Turbo Kit is designed to produce up to 400rwhp for the 04-07 Mazda RX8.
Which means if I buy the kit I should be able to ask for the 400hp. It was what it was designed to produce. If not change the verbage. It is very misleading. May produce might be better.
To make 400rwhp or not to make 400rwhp that is the ?
