It is your money... But I'm trying to help you see why it will be waste of your money...

That manifold is JUNK!!! Go look at other turbo manifolds... Others have much better design!!

If I were to run the turbo on renesis (I will never do as I think its waste of money) I would get either greddy manifold or mazsport, get a nice small ball bearing turbo, and get that powermod ems or other piggy back that will let you datalog and tune yourself. The whole cold air intake BS with 2-3 90degree bend is BS. Just put a filter or screen on your turbo. IC is important when you get into high boost.. but you are not going to make more than 10lbs with out going into changing your fuel system.

I mean, if I were to go do all this, I would just put a REW with stock twins (99 280s)! Thats what Mazda should of done fromt he beginning. with 280 99 twins, you'll get great response with max turbo potential of about 380RWHP (16-18lbs) and could run it reliably.

Guys,

MazdaManiac here in Phoenix has probably the best kit on the market for making power (Greddy Kit with upgraded turbo). He also is an expert on the Cobb Access port, which is quickly becoming the tool of choice for unlocking the potential of the stock Mazda EMS.

Hope He will get on and describe more about this Cobb Access thing....

Thanks Tim. You are too kind.

No. Amemiya re-badged the GReddy kit for his A/T application. Repriced it accordingly as well!
The GReddy kit fits all RX-8 applications without retrofit, so Im' not sure what the JDM response was to the Amemiya offering.

I'll jump in your thread about that.

Its interesting to me, coming here for the first time, how insulated the markets can get.
Some of the discussion in this thread is straight out of RX-8Club, circa 2005!

You can read about my GReddy upgrade on my site (link is in my SIG - click on Satan's Hairdryer)

As far as output from the various offerings (build quality aside), you can use these graphics for comparison:

Curious as to what your $6200 kit includes. I briefly looked at the website and saw just a garret upgrade kit and the accessport listed. What does the kit you have listed for the dyno stuff at 6200 include.

Also what exactly is the biggest holdback on the engine. I guess I'm more use to the 7's where its almost the sky's the limit (within reason) with turbo size, boost, etc. What exactly is holding the 8 back, is it the exhaust ports, or what. On the 7 its common to see 850cc primarys and 1600cc secondaries yet on the 8 it seems to be 5-600cc injectors. Are we speaking in general terms as a "easy" bolt on without major modifications and thats why leaving the option of new fuel system etc opening alot more doors or is it just the engine itself.

Thanks for chimming in on these posts too, its nice to get some good info for those that are interested.

The upgrade kit is $1800. That price is the upgrade kit plus the GReddy base kit plus the AccessPORT.

Its going to be interesting in making the attempt to bring people up-to-speed here. The last few posts above are almost perfect examples of the kind of thinking I was referring to in my previous post in this thread.
At least its not as bad as 7-Club.

There is a LOT of old thinking out there that simply isn't in step with modern technology.

Really, I'd be happy just to see people stop using the word "boost" all the time when they are talking about FI. Its meaningless.
