one of my cars will hold 400whp on stock internals 
but yes, as ken so eloquently put it, the longer you run high boost, the greater the chance of parts failure. This is why people have ebc's with multiple settings. you have a daily driving setting, and then a race setting.

Two blown motors isn't speculation. More power = more wear and stress. Will it be enough stress to kill your motor? Maybe, maybe not, Just recognize that the more power you make on a stock motor, the bigger risk you're taking. It might bite you in the ass, and it might not. Time will tell either way.

I have been running 10-12psi since I got the kit. I don't have dynos for the 10-12psi so if you read the sig it just shows the whp for the boost I dyno'd.
And I find it funny that a few tuners that have alot more experience in the 2.0L & 2.3L Duratec and turbos have said that the 2.3L can handle higher boost than the 7psi limit!
It is always someone in every forum to add limits to something they don't have any real word experience with. And always when the limits are passed it is always a factory freak!
Fact is there is no set safe limit...7psi is your opinion. I'll go by others that I feel have alot more experience with the 2.3L duratec and turbos. And I'll go by what I experience!
Not sure if you just want to be one of those people that can't be wrong or even agree to disagree because it is a matter of opinion....But it is simply that...Opinion!
There is more out there that say 7 - 10psi is safe than there is saying that you need to upgrade internals after 7psi.......
Oh wait you are selling internals....I see the light now! (poke)
To sum it up.
It is my opinion that 7-10psi is safe with all things considered!
You can't determine 7psi is the limit with a single blown engine without knowing if tuning was at fault.
And it is a giving that something will break, it is the chance everyone takes modifing a car.

But it is specutlation when other factors are not taking into consideration.
As stated I can blown an engine with 4psi, does that make 3psi safe?
And I agree more power does = more stress. I actually agree with most of your post. As time will tell.
But throwing out speculation that 7psi is the limit and then you need upgrades is more speculation than saying you can boost more as many are doin it!

Just remember that when your engine blows, Ken is also there to help you out

I understand this. But if you read my post then you will see my point.
This is uncharted waters as with ever new model car out there. And you always find someone saying 7psi is it.
Just like MarcyMotorsports stating that rods would let go at 7psi. Well now you have other companies pushing it further than that and saying they don't know why that was stated as they are holdin up find at higher levels.

the reality of the weakness of this engine has nothing to do with how many rods i sell. there is no light to be seen there but i knew once you had exhausted all of your other illogical arguments you would bring that up. to sum it up, as you say; i deal with these engines stock and not stock every day. more real world experience than anything you have thrown out here. tuning was not the fault of these engines blowing, it was the increased wear on the engines and the inherent weaknesses of the engines themselves. you speak volumes about the value of your own real world experience of one car but disregard the real world experience of three or more vehicles who have been under similar conditions. you are one of those people who seemingly believes what they want to believe as long as it fits his own situation and conveniently ignores factual evidence, proven history and practical application of hardware when they don't want to believe that it might possibly contradict thier own 'reality'.
i don't really need to reiterate because others in this thread have done so. if you want to believe what you believe, please feel free. but you can't convince me when here you have one car that runs fine, perhaps for a few months at most now - which i might add you conveniently failed to disclose - whereas i can say i now know of three cars whose engines did not handled it and more cars whose engines have fallen apart from other higher horsepower applications. so yes, i agree to disagree with you, but i also will be more than happy to have these kinds of debates with you when you erroneously try to apply your one time personal experience and perhaps long term luck with this car to other people interested in modifying it. the numbers speak against you, the data speaks against you, plain and simple.

and by the way, don't even attempt to question my credibility or motives when i give intelligent advice. vendor or not, i have been a member here for years longer than you and have enough people who will speak to the fact that my first priority is the well-being of people here, not earning a buck. i run my business to benefit this community first and foremost and i often sell at zero profit or at a loss if it means taking care of a fellow mazda owner. if you are so out of arguments that you need to take a cheap shot like that, then you have obviously picked the wrong facet of me to attack and its an ignorant insult at best lacking in any sense of rational argument.

You have to be kidding me...what can't you understand from my post.
My opinion...your opinion. You have no facts to back-up what you think is real!
What are your facts that these engines were from wear? Mileage, did you tune them, hell were you even in the car when it blew.
I can question your creditiblity all I want as you can't grasp that this is all opinion....keep it coming
It doesn't matter what you sell and who you sell it to.
Doesn't matter your post count or how long you have been a member of this forum.
Your statements on the Duratec engine jeapordize your intelligence and creditibilty!

so let me get this straight..
the other engines blowing is apparantly not fact. my experience turbocharging cars is not fact. my daily work on these vehicles is not fact. the documentation and word of mazda master technicians whose input helped design these engines is not fact. other engines with similar design and decades of forced induction research is not fact. my own disassembly of these motors is not fact. you have a strange definition of the word "fact". apparantly the facts are whatever suit your own case at hand. good for you.
your opinion is based on your own car. my opinion is based on experience and fact from multiple other reputable sources.
you talk about intelligence and yet making a simple sentence or spelling more than one word correctly is a challenge for you. as for understanding a post, you seem to have a problem with that as well - I never said a thing about post count. You are the two dimensional moron who insinuated I was making this argument out of greed. I never claimed that my time here or post count had anything to do with the 2.3 liter engine. I proved my knowledge of that without even bringing that into the equation. You had the idiotic audacity to question my morality and character and thats what my time here was in reference to.

Captain KRM P5 said:
Fact is you can't answer any of the questions that willprove you either wrong or right.
Fact is that you are trying to dress your self to be some great know it all tuner/engine builder/turbo maker
But in my eyes you are avoiding things and making yourself look like a joke that only sells parts!
I think it is funny...what else you got...since you can't answer questions to prove your case or keep this on topic.
(hah)

funny how no one in here is on your side. and for the record you took it off topic first with a personal jab, so heed your own advice in that respect. i and a few others in this thread have given you plenty of credible evidence which you have chosen to casually disregard, countless times. do i need to repeat myself and continue to show you for the narrow minded ignoramus you are? what and i others have said has already been credibly echoed. if you choose to ignore that, then by all means do so. if the practical measures i and others have already stated mean nothing to you because your own opinion does not allow you to see reality in them, then you really are incapable of furthering the argument or seeing a point in anything but your own "logic". avoiding things? you have no answer to anything i have said in this thread! thats what i call avoidance.
