i do agree that the rsx is pretty impressive, but if you say that the rx7 had good times because of the turbo, well that's just making excuses... lets put it this way, how about if you took out the vtech in the rsx?? heh, go figure...

rx7henry

I was talking about 6 port non turbo rotary engines ofcorse. Regular 13b na's, like on the fc's and gsl-se.

The "vtec" is like having a 6 port manifold on a non turbo rotary, where you get a nice pull from 4k and up with more air/fuel, and secondaries. I would say turbo the rsx, and that would be more fair. na-->na, boost-->boost sounds about correct?

Dude, the RSX is a fantastic car out of the box. Good performance, reliability, and fuel ecomomy. On a good day with a good driver it may be able to keep up with an FD on it's bad day with a bad driver. But all things equal the FD would take it easily. My FD is stock touring and I can assure you it does.

come to think of it, you're right, na vs. na, and boost vs. boost sound right, but a 2.0l vs. a 1.3l does not sound fair... everytime, i am impressed on how a little 1.3l engine can be compared to anything more than what it is, especially those 5.7l ls1's... now a N/A 2.0l rotary engine sounds fair to me, in which is a different story and totally off topic, yea i know... but if you are comparing n/a and turbo, then might as well compare the engine sizes as well...

I know I know. When it comes to smallest displacement and maximum power output the cake goes to the rotary engine. Just looking at production engines and fuel economy, Honda seems to do a hell of a job without forced induction. I know a lot of members hate them, but they are still using sub 2.2 or 2.5 displacement to make the power they do. I'm not trying to market the Honda name around here, but I hope this info will give the original poster a sense of what he's racing, as its not your garbage economy civic that you're competing against, so there isn't much to be ashamed of. I have a twin turbo 300zx and my friend with a fully bolted on rsx-s beat me (he was running a 13.7 & I was completely stock; I admit loss as my car isn't the lightest [stock13.9]), but once I did the basic power upgrades along with a good ecu reflash I choke him worse than Homer does Bart (leaving him literally buslengths behind [my car breaks 12's btw with about three or four hundred dollars in mods]).

Ok, I have installed PFC, DP, and Highflow cat. My boost is reading 11.3 PSI with the PFC, so i guess i dont have a boost prob. I raced my cousin now, and completley demolished him 4+ cars 2nd to 3rd gear run. Im going to say unless my cats were clogged, (highly doubt do to low mielage and condition of cats) a 05+ RSX (which are quite a bit quicker than the older ones) can hang with a Rx7. I was in my cousins car when he beat a 2004mustang GT stick, with exhaust. Im sorry to say it. but i believe it.

BTW- WOW my car feels better with PFC, DP, HFC. It is AMAZING. Smoother and the high end just is great. Again i completly raped my cousin this time, amazing him. Power difference is huge. The noise too is just emaculate. Waiting for m2 catback to come.

ill beat a type s with my 91 fc na

Good kill.

Hahahaha, dream on... turbo fc's have a hell of a time beating them.

So...you replaced both of your cats with aftermarket parts...and you got a huge power gain, and you're still not convinced that your cats were clogged?

I'm sorry man, the RSX is a nice FF luxury sport coupe, but it just simply can not hang with a car that makes 45hp more stock. The RSX only weighs 50lbs less than an FD, and you just lost that weight with your mods. But 50lbs is not going to compensate for 45hp and 75 lb-ft. It's just not going to happen. I'm glad you guys like and respect the RSX, but realistically speaking, there was something wrong with your car before and it was that the cats were clogged.

it was your cats... There is no way in hell that you went from losing to your cousin to beating him by +4 cars because you added the PFC. The ECU does not give you more power (unless you are at a dangerous lean threshold) the ECU allows you to run MORE boost which equals more HP

is your PFC tuned or are you runing on base maps? just wondering because IIRC the stock ECU runs richer than the PFC base maps.


don't be surprised if you begin to spike or creep after adding the CB. You should get a boost controller to help with the spikes. For the creep either you can tune for it or port the wastegate.

ArmenMAxx

iTrader: (21)

Its on base map. I didnt just add PFC, i added DP, HFC. And i doubt its going to spike because the PFC controlls boost. Also, porting the wastegates is necessary for a midpipe, not highflow cat. Is my car supossed to boost more than 10psi with PFC? is it safe to go higher on basemap?

SLOASFK

iTrader: (5)

I wouldnt suggest going higher on the base map. The PowerFC doesn't compensate for boost fluctuations like the stock ECU does. The Stock ECU runs rich and compensates for overboosting, to an extent. At this point, you'd actually be better with the stock ECU and not the Power FC, unless you're going to tune it for the added boost.

Porting the wastegate is nessecary for a turbo-back exhaust, period. even with a high flow cat, as soon as you put a cat-back on your car, you'll start over boosting, and your Power FC will no longer be able to control the boost.

ArmenMAxx

iTrader: (21)

WTF!! people told me putting on DP, HFC and CB, ill need ECU upgrade. NOw you guys are saying that i need to put the stock ECU back on?>??? THe PFC basemap is made for DP, HFC, CB, Intake, and IC. So why would you say i need to put the stock ECU back on? and im pretty sure PFC is richer than stock ecu. DOnt know if you guys know wats going on. 1/3 of the people of this forums that ive read about have similar mods as me with base map. COME ON!

SLOASFK

iTrader: (5)

no, sorry if I implied that you should go back to a stocker. What I meant to say was that you should get your PowerFC tuned because it's not going to compensate for your mods, like the stocker will. Once you get a cat-back then you'll really start to see boost spikes and creep too. Check out the PowerFC subforum and look around. There's a sticky in there with downloadable maps for your specific mods. I'd sugget putting one of them on your PowerFC.

My suggestion would be to get a premade map on there and port your wastegate. with or without the PFC, if you don't port your wastegate, you're going to have issues down the road.

this thread made me disgruntled initially...

half the time i wouldnt even get a chance to race an rsx- s because i guess they just figured id win (logically) but on a number of occasions i had my fill of fried rice and i never had a problem walking on an rsx - s , even before i had my downpipe.

p.s.- basemodel 5speed 7 weighs thirty pounds less than a 6speed rsx-s '06
My boost batter before the downpipe installation with just the cat back ('95) ran 12-10-12 pattern and i never ran lean, not even after the downpipe, nor did i get boost spikes, but i had the stock cat still so i supose that controlled it. But idk why i was still catching 12psi max boost when it seems most of your guys are getting only 10-8-10 patterns


im glad you fixed your car, cheers to burning the rice instead of the rice burning you, not that i have a problem with honda's...haha

You missed what I said. I said that the PFC did not give that extra HP. the DP and Hiflow cat did. Hence one of your cats was certainly bad.

I take it you bought the boost control kit... If you didn't than you are not controlling ****.

Are you 100% sure on that?

Adding a mippipe will most certainly will result in boost creep. *but* some people have experienced creep with a DP, HI-flow cat and an exhaust. Every set up is different that's why I said:
If don't get creep then great if do, don't be surprised because it just means that your setup is very efficient.

not unless you bought the boost control feature and actuall set it up. The PFC primary fuction is to p[rovide fuel for a given boost.


**** no. The stock ECU runs richer than the PFC base map. So you are actually safer with the stock ECU.

The PFC NEEDS TO BE TUNED! that's the whole point of getting a stand alone ECU. At this point in time you took a step back in your mods.

Montego

3 mods rule... erroneus misguided antiquated rule. What I'm saying is that you need to get your ECU tuned.

well if you are pretty sure...

read post #30.

did you know that with the stock ECU you can run a:

MILD STREETPORT, CAI, UPGRADED IC, DP, MP, CB and still be safe? it has been proven with actuall data. Not hearsay hence throws out the 3 mod rule out the window.


How many of those people come back and say "I blew my engine?" Those are people that give the FD a bad rap. Most of them are college kids who withing a year's time mod their car without thinking, blow it up, and then sell it while telling people how bad of an experience they had with the FD.

I will say it again the whole point of getting a stand alone ECU is to tune it. That is how you get your gains. Setting the timing, and adjusting your fuel curve for a given boost. If you bought a PFC with the intention of just running base maps then you have wasted yout $$. Should have gone with a pettit or M2 ECU instead.

The same day I installed my PFC i got it tuned.

I actually take offense to that....You need to stop and analyze what is going here because it it obvious that you are not.

1) Even though we all told you that your car was not runiung right you didn't accept at first. You just gave props to the rsx.
2) the 3 mod rule is an old way of thinking
3) You don't believe that the PFC base maps are leaner
4) You are not utilizing the PFC's potential
5) You thought that the PFC automatically sets your boost
6) You believe that the base map of the PFC gave your HP gain
7) Just because a bunch of people are doing it you think it's ok

apparently I do not know what I am talking about (remember I'm the one that told you about the cats...) I've only had this car for nine years but what do I know? BTW Those were my mods for about two years (+30K miles) on a STOCK ECU and I WOT'ed all the time. Never blew my engine... that is until I accidentally hit 23 psi because my wastegate line came off (i had a tuned PFC at the time). I had 52K miles on that engine and it ran just as hard as the day I got it rebuilt.


This is how you should treat the forum:

don't just go by what people say. Listen to those that have actual data that backs up their reasoning. Then mod your car and monitor and conclude for YOURSELF what is safe and what is not.

sorry 1# is untrue... I take that back. You did go and search for possible culprits that would lead you to be down in power. You just didn't believe that it was your cats.

but if you read his post from the re-race, he still didn't believe it was his cats. He simply thought that he gained 80hp from installing a dp and hf cat.

13b type rs

i do think it is right, i raced my 97 type rs with a JDM type r before, i never loose even when i was totally standard. before u modify your car, i suggest u check ur motor, maybe your secondary turbo is out of function(caused by bypass pipes leaks etc, it is quite a complex system ), so u still can feel pulling from the primary turbo, but not from the secondary turbo. the point is that at higher speed, u r more rely on the secondary turbo, so if ur secondary turbo fucked, then it may cause u the problem u mentioned. other point is the compression test, if u r lossing power by low compression, then u need to looking at rebuild the motor, mate

Do you have any posts to back that up? I've yet to see anything contrary to the 3 mod rule.

it's all over the place... The 3 mod rule got proven wrong five years ago.

Wade performed the lambda tests with a wideband O2 sensor himself. I had posted this already but here it is again.

Wades own reply:


Most importantly I go by my own personal experience. Those were my mods that I listed (MILD STREETPORT, CAI, UPGRADED IC, DP, MP, CB ). I ran for almost 2 years on a stock ECU . Then I got a PFC because I wanted to go with higher boost levels.

no dream it has happened already, i cant beat them type r integras tho always about one car ahead of me
