Must remember that dynojets read much higher, due to an adjustable, arbitrary "factor" that the user can adjust as they see fit.
Also, remember that comparing dyno numbers in different cities, with different dyno manufacturers, and different times of the year can vary WIDELY and should not be used for comparison. The proper use of a dyno is a before/after on the same car, preferably in a single day, after some changes have been applied.

EVOs, depending on model, typically run 19psi, tapers to 17/16 -- and make up to 280ish hp, depending on model.
02-05 WRX -- 13.5 PSI (22x hp models)
And there are tons of other examples... stock SRT-4's run about 11ish psi, etc. etc.
But the original comparison isn't fair since we're comparing stock, low-compression motors to aftermarket-managed, NA-level compression motors. It's all in the tuning... factories tune for 100k miles, but your off the shelf turbo kit tunes for best power-per-psi.
Seems like a waste, sure... but if you start turning up the boost, a scion or otherwise NA-converted-turbo would go nuclear FAR before one of these factory turbos would.
In the end, it's apples/oranges.

I still don't understand why. It makes almost as much power as an Evo 9 (and will with some mild exhaust work). It has a limited slip. It comes with nice Potenza's. It puts up great stock numbers.
What's so disappointing about it?

you know somethng? given all the inaccuracies with dynos, maybe we should relegate them to being strictly engine tuning tools and use a more consistent measure of vehicle performance? something like kN of force.
this way, all you really need to know is how quickly your engine can spin up the tire/rim combo to max rpm in a given gear. of course under real world conditions this number would be lower due to traction and vehicle mass issues, but it would certainly be consistent.

But then, how would ricers say their intake is better than the other? How would they bench race 2 cars over 800 miles away? How could they justify pulling imaginary numbers out of their **** and claim their cars make 15 more HP due to the intake?
Such logic destroys the natural order of idiocracy. We can't have it!
Inertia-based dynos are becoming more common, and are much more useful, if trying to accomplish some sort of one-run-estimate... in order to compare vehicles one after another, such as in a dyno day.

Unless your parents can bail you out money wise, with no questions asked I would not do it. I used to race in high school but where I am from something like a tc in any form wouldn't compete. Most of the guys were running around with 500hp v8 mustangs and DSMs. The most valuable thing I learned is to not seriously mod a car you cannot afford to fix when stuff breaks. Especially with college coming up you may want to rethink your plan. All through high school I drained my money on my 1983 Camaro(yes the ones with the mullet mobile stigma). The body was immaculate but the engine left much to be desired. I built a 355, then that wasn't enough I rebuilt it as a 383 with forged internals and AFR heads. Then when 12's wasn't enough I saved up and got a ATI procharger. I was 18 running around with a 600hp Camaro. By the end of the summer before College I had blown up the motor. Everything was done right, but stuff just happens when you abuse your car all the time with big power mods. Well, I was SOL and had to go through my first 2 years of college with no car. Eventually I got scholarships got a $2000 Jeep Cherokee. Then I started doing engineering internships and can finally afford a car that does not break down every 2 weeks. I now have my tc and couldn't be happier at the moment. I still have the Camaro. As you can see it now supports a 350 goodwrench stock crate motor with about 200hp. My dad bought it for me because he was sad to see the car sit in the garage for those years.
I think what I am trying to say is just be careful with what you think you want, because it may not be what you want at all.
P.S. for the price of a turbo kit you can buy an older performance car and make it just as fast without risk to your DD. Those rich kids will feel much worse if they lose to a rusty DSM or something

I personally purchased my turbo kit about a couple months after I turned 19. Great investment for the car, but not a great investment when it comes to personal income. I recommend doing a lot of research before turbo'ing the car. My original budget to turbo the car with the Greddy Bolt On Turbo Kit was $4,000 and I ended up putting $6,000 to get it running how I wanted it.
As bennyboopy mentioned above, the more mods you do, the more expensive it gets, as well as stuff seems to always come up that you have to fix later down the road. So far within the year of my car being turbo'd, I've had to replace my clutch and flywheel, my throwout bearing is bad after 6 months of replacing the clutch, i've had my radiator hose get cut because replacing my crank pully something went wrong when I was driving and hit a massive pothole. Those are just a couple of things I've had to fix. Nothing major at the moment, but I know that I always have to have a backup plan if something does come up, which usually involves money.
Good luck on the journey of making the car faster!!!! It's a lot of fun being able to keep up with some STI's & EVO's.

we have the larger motor
everything the mazda has can be put on the tC for less than the cost of the ms3 itself
only thing it really has going for it is its 1st and 2nd gear boost limiter thingy and its a six speed
all cars can be fast with the right amount of money
but the tC can be faster than the MS3 with less money
