First off thx for clearing a few things up for me in that other thread. Like I said I aspire to hit as close to 200hp as I can N/A and have no intentions of any formal league racing at this point.

As for that celica comment I made I got that from comparing spec sheets I got from the manufacturer in AZ and when comparing the onyl specs different were the bore and stroke for the 2 engines. I was aware if it was from boring the same head to two different sizes or like you cleared up for me 2 different heads from the beginning.

Lastly I had a question for you, I saw in another thread a while ago you replied to someone about the most restrictive parts of the system in the new Pro's. Well I have an 03p5 and would greatly apprecuiate it if you could let me know what those were again. I cant find that thread anymore (or Im just blind)

Thx for clearing that ish up man,

Why standalone only though, Pseudo? Is it just by preference? It seems to me if you can make a piggyback work and have it control fuel and timing appropriately, you don't really need the standalone and the headaches associated with tuning it. With the piggyback you can still let the original ECU control housekeeping chores that would be a pain to tune on the standalone.

The stock ECU is not very receptive to piggyback systems. For a N/A setup, your best bet for making 200+hp is a standalone.

Doomer_MP3

Ahh, it may seem that way. However, tell that to the guy that found using a permanent marker to break the $100million CD anti-piracy format destroyed years of work in a single day. Yes. The ECU may not be easy to crack, but perfworks claims to be tuning and almost ready to sell a piggy back with COMPLETE fuel and timing control. I still cannot see why a standalone is necessary if you can completely control the two things you are aiming for.

Motor undersquare? I am not sure what this is,sorry nub here.
The rod ratio can be changed for the better witha forged rod swap? Or do you need more work than just rod replacements?

I am planning on the Jspec intake cam within a month and if I can find an exhaust cam that also.

Intake manifold, being one of the more expensive parts to replce will prob come down the line a ways but is still planned. Any good sites for manifolds for a new p5?

I already have a cat-back ractive system waiting to be installed, do I need to do more than that? (Headers are planned to be one of the next 4 or 5 purchases)

Standalone like the blitz or AEM controller that are usually mounted below the radio? That is also planned but I am not sure how soon, Not sure when it becomes a necessary item along the mod plans, as in after what mods do I really need a unit like that.

Any other info, especially concerning the square engine and rod ratio as I know very little about changing these features.

You know I started out thinkin, alright intake, headers and exhaust and thats it, now I am planning like 2-3grand of mods over the next year, year&ahalf. =P Damn its addictive.

Thx again everyone especially Pseudo, and any more info is appreciated.

I'd advise against the J-spec cams. They're not all that a cam can be and if you're wanting 200 hp, they're not even going to come close. Get some billet blanks from MMS and have them ground to a more aggressive profile. Not really higher lift (unless you want to rework the valves) just more duration, say >220 degrees. That and some head flow/porting will go a long way. And get a good header.

If 200 hp is really your goal, my very best advice would be to save the money you'd ultimately spend on the Protege and trade it in on a Evo VIII. I've talked about that for a while, but I just drove one last weekend and that's some real zoom zoom! I could put another $20k in my Pro and not have what that car is.

p5sunDevil

well with 20k I know I could make the pro to be as good if not better than the evoIII

And saving for a while for the evo isnt really probable right now since I got my 03 p5 for 14,900 and the evo starts at 28 base, thats double what I spent.
I am planning on not going too far with the pro as in about 2-3 yrs I hope to be getting a wrx or starting a project car from an old silvia.

Any input on how much the average is for a good port and polish.

Sell the Pro get an 84-91 rx7 with a blown motor. Then get LS1 motor and tranny. Convert a v8 into it. The car ends up lighter than stock by about 100 lbs. You'll get 30mpg run 12s and make everyone on gods earth jealous because you can get to yoru number 8 spark plug with no problems. Oh yeah you can do this all for under 10 grand including the price of the car.

p5sunDevil

that rx-7 idea and the silvia idea I want to do are both very possible except for the down time the car will be under when doing all of that to the car, even with a cherry picker for the engine. It is more doable as a second car as oopsed to a primary driver car.

Once I have the extra cash I will be starting down that route.

Bruce95fmla

I read in Grassroots motorsports that the mp3/p5/sedan ecu can be fooled with the piggyback but only at partial throttle, once you go full throttle the ecu bypasses the O2 sensors tottally , thereby rendering your piggyback useless.. and you could be in deep @@it
Bruce
p.s. oh yeah I subscribe to grassroots now ...lol

p5sunDevil

thats understandable but I am not looking at a piggyback unit, more of a stand alone engine management system, like the AEM or APEXi AFC and so on.

^CL4RK^

Doesn't undersquare have to do with the stroke or something? Haha. Jw

Doomer_MP3

Yes, with currently available piggybacks, yes. But the piggyback that perfworks is finishing up right now gets by this issue. I don't know how, but hes doing it, and its under $700. Does fuel and timing all the time. You should search the other board and look at some of his work. Quite a knowlegable guy.
