wrench - damn, got confused about the headers 
topher - i have custom cams....i bought the blanks through mitch @ p5online.com and he got them through mazdamotorsports....my specs actually fit on them without having to reduce the base circle
p5owner - as long as the exhaust is mandrel bent and the mufflers/resonators are straight through design, they loose almost nothing over a straight exhaust. if you have a swap pipe for the cat you'll have no worries.
all - it still can be done....just watch me

you can get the engine that is used in the speedworld challenge cars for about 15 grand...
as i realized going n/a is NOT worth it ...
i saw the light and went the turbo route ....
160whp is doable n/a...
headwork ... compression around 12-13:1 compression...
and lots of tuning..
and not to mention you will need to run 100 oct or higher daily to stop detonation...

thats correct...I talked to that people, the MOTEC Tunner was there, talked to him too. They said its very expensive to do that job, plus the engine does not HOLD that kind of ABUSE (driving on high rpms for extended periods of time).
The engine suffers a lot of wear and tear...But is a very fast car.
I have some video clips if anyone want to see how they run, they sound like a fly in an ear.

It is very possible with waht you got listed. You wont be able to without ecu tuning though. With ecu tuning and high comp pistons it is very possible, you will probalyy have to get more agrressive cams though. Also 220 hp to the wheels and flywheel is two different things. 220 to the flywheel most deffinettly in my oppinion but their is going to be alot of trail and area since know one has really pushed even near that yet. You have no guidline what works and what doesnt. Also their have been alot fo dyno charts with catback, headers intkae and thats all making 115 hp and 120 hp, that is a big jump for just so few mods. Do the search and you will fine the post. Our biggest bottle neck in my oppinion is cams and header from factory.

yes the stock cams are way to small for any decent power
Right now I'm looking into getting an FS-ZE intake manifold ported and polished. I'm also coupling a polished corksport throttle body to the mani. Soon as wagner finished his header, that will be on as well. My goal is to hit 170whp. Enough for me. Thus far I have a 2.5" bosal cat-back system with the cat removed, SUN grounding system, AEM-SRI (which I just sold for an INJEN-CAI) NGK Plugs, Sparkco Wires, etc etc..My next step is the having the intake mani polished..That and steal a lot of money for the project.

personally i wouldnt get the fs-ze IM. it's still not a dual runner design. as far as i'm aware it only has slightly larger runners. you'd be better off just porting and flowing the original IM. cheaper and will give the same results. the race protege's use the original IM

why dont u want to get forced induction ? ? ? ?
what about the essential speed custom intake manifold for the P5? here is the link to check it out-http://essentialspeed.com/shop/detail.asp?product_id=EsManifoldsproto50004&&cat=&category=&cat1=15&cat2=

personally i'm going na because this car will be my wife's car and a turbo is pretty much wasted on her, but i still want to play in the mean time. also, na is a lot easier and doesnt require as much constant maintenance
the FS-ZE i'm referring to IS dual-runner.

I think a more feasible target is 150 whp N/A. You aren't going to get over that without some serious mods. A basic turbo kit will put you over that thoe.

it's not a dual runner. it's only slightly different to what you have now.
Yeah, that style I suppose. I wasn't planning on picking it up from those graverobbers though. Although, the do distinctly say its dual runner.

they do, but they also claim it'll raise the power to j-spec range (bs), but it is definately not a true dual runner (ie two runners going from the plenum to the head).
If you want to read a long discussion on it read this thread:

especially from around the middle on. The major difference between the jspec and the uspec is the added resonance chamber. The castings are obviously different, and there maybe some slight differences in the runner length and cross section area, but the runner/VICS design is the same (proven by twilight)
edit: oh damn, didn't mean to be ganging up on you.
