AHHHH! I need more power! Im not quiet ready to turbo, but I have the K&N short ram intake. I also installed OBX headers, on a 2.5 in magnaflow, complete exhaust... No Cats, High flow muffler, Plugs and wires are done... Now What? What else can i shove on there to pull a lil harder....?
More Power!

Better cams, 626 or even better a protege garage manifold that removes vics and vtcs , underdrive pulley, those 3 right there will give you a REAL GOOD horsepower increase as an n/a....after that..just go turbo or management with higher compression pistons

get like jspec cams, high comp pistons, underdrive pulley, EMS ..... with that right there u'll get some nice gains 
-------------------------------
how does the single cast iron intake manifold work on the N/A, i know its good for FI, but havent heard from any1 thats na, just interested if it worth $$$ and what gains????

i would go with an mpi or similar piggyback, or if you can find one, an mp3 ecu would be a cheaper alternative. mpi alone is probably worth an extra 15-20 hp. best bang-for-the-buck imo. you can get an mpi for the same price as cams and a udp, but the latter 2 are probably only good for MAYBE 10hp.

btw, vics is GOOD for n/a. Alot of the probe guys w/ the older fs engine go to alot of effort to add our manifold w/ vics because it gives quite good gains at the top of the powerband. If you're going to modify the intake manifold, i would just do the vtcs removal and port/polish. That only costs a couple bucks and a few hours.

Can anyone recall the guy who had the 197 whp protege? i cant remember his name, but yea, the cams and cam geard helped him alot, and i think he had the EMS for the 197hp run.

actually it restricts power in certain situations and release it depending on the terrain...some of the techs at mazda were explaining it to me, in fact they went in to my old manifold and changed some things so i vtcs would be less used in my car. the only time it will help you is if you live like on the side of a mountain. they were explainin that vics is worse if you race with it because it is restricting your powerband and power. i'm not quite sure of the complicated parts but i trust my mazda techs as they have worked on this for like ever and i have immensely obvious gains from the new manifold. doubt it? come down to oklahoma and take a drive in my n/a. i'd def like to see some info about these probes getting more power with it though, i'd just bring it up with the those same mazda guys and see how they could explain it, and thread links or anything?

some of the cams and udp have produced much more hp with other accompanying mods such as opening up the exhuast and intake. Also i do agree, the mp3 ECU would def be a quick power increase that you can usually get for about 100, most power say there is a 10-15 hp increase

if you aren't wanting to tear into the motor, do the UDP, a flywheel when you replace your clutch and an MP3 ECU.

everyone on the forums gets vtcs and vics confused. vtcs is bad, vics is good.
vtcs are the butterflys that sit half closed at start in oredr to reduce start up emissions... they just get in the the ay and tumble the air...
vics how ever (variable intake charge system) is actually an extra airway in the manifold that opens up at a certain RPM (4k i think) and extra space allows the engine to resonate the intake air better at higher rpms. (think of this varying engine piece as the mazda vtec... ha)
as u should know, thats how one intake or exhaust or header can be better, by having better resonating properties, or the property to make perfectly timed sound waves, esentially pumping air into the cylinder at the exact time that the intake valve is opened...
its like when u lower ur back window on the highway and feel that pumping... same thign essentially.
recap... VTCS (butterflys) bad, VICS good.

No, a short runner works best for low rpm and long runner for high rpm (note this is higly generalized, but that is the reaon for the VICS system).
Little Beavis said:
It's the other way around. Long, smaller-bore runners are better for low rpm because flow velocity is higher at low rpm. At some point in the powerband (I heard it's 5200rpm) there's a bottleneck which VICS overcomes by switching to the short, larger-bore runners.
Not too many cam options for our cars. Most people go with JDM cams, available at SR Motorsports. They call them MazdaSpeed cams, but this is confusing nomenclature since the MazdaSpeed Protege has the same cams as the normally aspirated Proteges.
Sometimes you can get them used on the f/s forum, and I have seen a new JDM intake cam on Ebay, too.
