225hp n/a p5

[stdntDrvr]

is that possible?
that's my goal...here's what i've done and what i plan to do...any other ideas would be GREATLY appreciated.

so far:
injen cai
j-spec cams
ur crank pulley
rm header (be here next week)
MP3 ecu
1.8L Updated Coil/wires
Mazdaspeed P5 axle-back
Iridium plugs

i plan on adding:
AWR Motor Mounts
nology plug wires
UR Flywheel
ACT Street Performance clutch
Braided Clutch Line
FS-ZE intake manifold
FS-ZE 10.4:1 Pistons
Forged Rods
Auto-Exe Rare Earth Grounding Kit
Quaife ATD Ltd Slip Differential
cam gears

i plan on doing the pistons and cam gears at the same time and having the car tuned.

is there anything else or any suggestions for me meeting my goal?

Thanks!

Over 100HP/liter for a NA engine seems very unlikely or even impossible...but I don't know for sure...you're talking about more than doubling the stock HP without a turbo or supercharger...

I'd have to suggest a full cat-back as opposed to the axle -back. Also go with a high flow secondary cat, unless you plan on removing it (obviously!) Since your engine will be ingesting and combusting larger air/fuel quantities, it'll need to expell all that. Don't go with anything to large in diameter as you will lose too much backpressure (and torque), but it definately will need to breathe better, not just inhale better. MHO. But at any rate, that's going to be quite a trick to get 225hp. Good luck.

yeah, once the header gets here i'll be cat-less...i wasn't sure if i should open up the exhaust more or not...so i had planned on sticking with the axle-back...but i SHOULD go with a cat back?
Thanks!

Check out our new Engine management / Tuning forum...you're going to need one! Oh...and head work.

to get 225whp you would need some higher compression pistons 12to1 to 13to1 range and some really big cams.

I would reccommend it, but I'm far from an authority on such things. But think of it this way......If you're running a marathon, you need to breathe good, right? Now, how would you feel if you could inhale great, but when you went to exhale, you could only do it through your nose? Try it. Take a deep breath through your mouth, then exhale through your nose ONLY. Feels restricted, and takes longer to remove the wasted oxygen (exhaust). Therefore, it takes longer to be able to take in fresh new oxygen that has the needed components to get your engine to run. Just a crazy thought.....All I know is that I've noticed increased (slightly) performance on a stock 2.0 with a full cat-back.

 

[stdntDrvr]

right, i didn't want to free it up too much...i guess as long as i don't have a 4" pipe on my cat-back, i'll be fine.

just about every honda motor is doing this.

Topher - with those mods, you don't even have a shot at 200hp, let alone 225.

 

[stdntDrvr]

which is why i'm asking for suggestions.

 

[Kooldino]

Turbo, NOS.

Head work might get you in the general vicinity of 200, but stil not.

 

[stdntDrvr]

n/a...and it can be done...just ask sunbelt racing.

 

[enry]

RSX-S hits 200 hp / 2L and that's with VVT on both intake and exhaust valves. Good luck!!!

better off with turbo, youll spend less money in the long run.

but if you have your mind set, you can throw in water pump/alt pulleys, head work, port polish intake manifold, full engine management, bigger throttle body, more agressive cams than the j-spec.

dont spend the money on the HKS ground wire kit, make your own.

 

[SuperSpud]

arent the tri point proteges putting down something like 200 whp? and their pretty maxed out.. its going to take A LOT of money to get you to anywhere near 200 whp.

port and polish, HIGH comp. pistons, engine managment, catless exhaust, headers, intake, new cams, valves and valvsprings, etc.. LOTS of money man....

 

[jersey_emt]

?
just about every honda motor is doing this.

But there's very few Protege motors doing this. Honda is a completely different game.

 

[Matthew]

well he did say 225hp not 225whp so he may be able to get that.

 

[stdntDrvr]

you people need to have a little faith in the 2.0

 

[thewrench]

Topher, you coming to the meet next weekend. I can go over why 225whp is really out of reach there, but, geez, it's just too much to rehash here.
