The kit is close to perfect. The installers aren't. The drivers even less so. That is the human experience.
That said, you would be hard pressed to actually find a weak spot in the system.
Even the GReddy kit as it ships is extremely good.
The problem is, no one installs it as instructed and just leaves it that way. Everyone wants to turn up the wick before they even turn the key.

How do you figure any of this? Having either system present in the vehicle will fail you on a visual test in any state that has one.
However, with the flash in place in the PCM, no OBD-II test (which is the norm in the vast majority of municipalities) will detect any failing features.
I've been passing emissions tests for years with complete custom turbo systems in place - even in the communist state of Maryland.
You are going to have to rethink that one. It was pretty weak sauce.
Its "taken", BTW.

So when you start your spin, please tell us how "safe" turbo is and how the longevity of the engine is/is not effected.
Mazda aborted power adders on the Renesis because the EPA holds them up to a different standard than you or I.
All power adders come at a price. Air is air and every motor has a limited number of hard puffs in it. Forced induction just gives you those puffs up front.
You might want to do a little actual research before your arguments get any more emotional.

Actually, they did a turbo, also. I have held it in my hands (as have several other members of this forum).
It wasn't "aborted". It wasn't economically or environmentally viable.
Mazda is in the business of making money selling cars. If the unit cost of production were to go up by 20% on a vehicle like the '8 which has exponentially declining sales in a regulatory environment that is already predisposed to the elimination of ultra-low efficiency motors like the rotary, why would they make that move? Because you would enjoy it?

It sure is! Especially since PSI is completely meaningless. There is a rather good article in one of the car mags this month about flow vs. pressure. I'll have to find it and scan it for you. You might like the pretty colors.

It has not, it will not and you are obviously complete inept.

See my facetious remark above this one. It still applies.

Products that, for one reason or another, I sell at a net loss. I guess I was biased all those years I was here before I had anything to offer.

Actually, the BHR/MM kit will be identical to the existing system. We are just cutting GReddy out of the deal. Largely because of the stigma created by ill-informed folks such as yourself.

See my reply above concerning this line of reasoning.

Obviously, I'm desperately hiding the fact that I offer a way for the GReddy folks to get their money's worth out of the kit. I wouldn't want anyone to know that, so I had better start "bashing" the Pettit system.

Oh yeah. I forgot. I was already at it way before now.

So why make such a feeble attempt at insulting it?

Once again - if you look at my record, I've been merciless on the Pettit system since the first day I set my eyes on it. I realized at that moment that it was a horrific kludge of Hillbilly engineering and opportunistic marketing and that was WAY before I had anything to offer.
The fact is, all of the things I've tried to "bring to market" here are just copies of things I built for myself. I saw a place for an improvement, I made the improvement and then I offered some people the opportunity to have the same success.

Sorry for the ad-hominem bits. I concede the argument to you because of them (its only fair). But the experience was quite liberating.
Now I know how the other half lives and its horrible.
I'll retreat to my little lair of deception and allow you to continue your great crusade of blissful ignorance.

I don't mind being called ignorant or making mistakes. I will continue to learn and becoming enlightened.

I will bite my tongue on the emissions part, as a custom turbo kits can pass.

Of course it is always good to have friends or bring extra money to the test. It is just harder to pass with turbo and they are, overall, harder on the cat.

I disagree with your point of comparing kits at different psi is meaningless, to the end result of HP that is displayed and the interpretation of the results.

If 13PSI gets you 330HP and another kit 7PSI gets you 300HP, than you simply don't declare "victory" with the higher HP.

"Power delivery" between the turbo and supercharger are different too. I still argue that which you prefer, is a "depends" that is best left to the customer.

BHR/MM would do well to sell their own kit, so that they can guarantee their customer has the complete list of recommended parts needed for a successful install and that customers do NOT have to buy unneeded parts to assemble a complete kit.

The MazdaManic Greddy Turbo upgrade kit and MM/BHR Turbo kit "perfect"? That remains to be seen. Though, there is no doubt that your turbo kit is very good.

There is also no doubting your passion for excellence.

...The installers aren't. The drivers even less so. That is the human...
Well that aspect, effects all FI kits, including yours and everybody else.

That is completely false. To pass, you simply tune your car correctly and show up. There is no bribe needed. The car is simply compliant. No one (not least of all the emissions testing station) cares whether it is TC or SC. Turbos are no harder on the CAT than SCs. They both create elevated EGTs because you are oxidizing more fuel.

How about the kits that deliver 280 HP at 11 PSI compared to the kits that make 320 HP on 9 PSI? You are still missing the point. Just like the old addage that "horsepower sells cars and torque wins races" (completely misguided as it is) is alluring, you should start chanting your new mantra: "PSI sells kits, but lbs/sec wins races!". Not so sexy, I know. But that is the fact of the matter.

Different is not always better. No matter what argument you might make for "feel", this is the data point: The best power delivery comes from the kit that produces the squarest torque curve and the most perfectly diagonal power curve. Whichever system's dyno looks like a backwards "lambda" (or an italic "h" if you prefer) will "feel" the best and win the race. It should be a resting see-saw in front of a picnic bench. Whatever.

That was the point. Make something idiot-proof and they'll make a better idiot.

MM upgrade Replaces the GReddy Supplied Mistu Turbo with a Garett Turbo where as Mazsport

GReddy Turbo Kit owners can now see an upgrade to their existing Turbo. Once you send us your Turbo, Mazsport will machine the compressor housing and install a larger compressor wheel. Rebuild and balance the rotating assembly. This upgrade will provide more HP through the mid and upper RPM ranges. This upgrade can typically be done by as little as three days turnaround.

Sorry if this is an ignorant question, but are you saying that folks with a turbokit such as your upgraded Greddy kit would be able to pass emissions tests in CARB states by simply reflashing the ECU w/ the AccessPort to a "emissions safe" map?

The racingbeat website has a description of the CARB rules at: http://www.racingbeat.com/emissions.htm

Based on my read of that site, it sounds like a turbo or supercharger doesn't necessarily automatically disqualify you on a visual inspection because it is "exempt".

Am I way off base here?

In states with a visual test, unless the system has a CARB sticker (or whatever exemption your stat may have), it will fail.
For the most part, only Cali has such a restriction.
Even in **** states like Virginia and Maryland, no code = pass.

Not sure. I had one going to a RHD customer, but he has, unfortunately, found himself in need of re-selling it before he even received it.
My other Pacific-Rim customer is LHD, so I don't know for sure.

Looking at pictures, it would seem not to matter, but I can't guaranty it will fit with no issues.

Re-Amemiya, Japanese Pro-Tuner, sells and installs the Greddy kit on RHD JDM cars. You could send them an e-mail- inukai@re-amemiya.co.jp . They could for sure confirm any issues or differences with the Greddy kit.

Interestingly, I think the Re-Amemiya guys would be interested in the MazdaManic upgrade too.

You can also ask Greddy/Trust too- http://www.trust-power.com/overseas/contact.html
