RS performance

[murph22287]

i have a stock rs engine. i wish to put some aftermarket performace parts on and i was just wondering if anyone can tell me what the greatest difference i will see in a certain partor parts.

 

[Four20A T]

Start w/ Aem's ver. 1 CAI......then move to headers and 2 1/4 - 2 1/2 inch exaust, and if your ballsie enough hollow out the cat(big difference in top end speed)......anyways that what i started w/ and my fastest time all motor was 15.6 @86 mph.....i have since gone turbo'd.......have fun w/ ur car.....

headers doesnt seem to be a very popular thing here on this forum. i dont blame them, a lot of cash and barely any results. think about it first

 

[pr0]

Get an Injen RD, does the job rather fine. I noticed a good difference in torque, increases the kick a bit.

 

[Evolver]

the most bang for th buck on our cars is the under drive pulley afx or obx

 

[kaoticdeath]

well i just have to say i dont see the point in spending all that money for an aem or injen intake buy a cheap 1 from ebay dump the filter they give you and go to auto zone and get a k&n cone filter for it you will notice a differenc in power with just that next get a header high flow cat and high flow muffler that will bump up your top end power after that you can get an underdrive pully then the only easy bolt on left is a bored throttle body witch does help alot after that you cold get your intake ported or get cams but then your talkin big money after that

If youre going deep into all-motor the header will help get those nasty exhaust gases out a little faster though little gains youre car will breath alot easier and you can do what i did have youre head ported and header port matched for a nice combonation.

But if you plan on slapping an intake and exhaust and calling it a day "like most n/a"then I wouldnt worry about it.

ok yeah dats obvious, once you already have mods for your 420a its not a bad idea to change your headers. but they wont provide an amazin amount of power as your first mod. as a matter of fact, once u already have mods and then you put in the headers... the amount of hp gains wont be that great either, the most you will have is a LIL bit of improved acceleration. i still think headers are not worth it unless its the last thing on your list.

 

[adgators99]

there is some misinformation on this thread. Headers will help with no doubt. some of the above statements are correct though. the first thing you need to do is get the air in via a cold air intake - any will work fine even the cheaper ebay ones, they pretty much do the same thing. you then after getting the air in need to get the waste out of the engine better. first exit is the header. you will not experience gains from the header right away though, you need to then get a catback exhaust system 2.5 with a high flow muffler. if you live in a non-emission area you can get rid of the stock cat also which will also help. once the exhaust is on there then the header will function better, but people generally forget that if the header is on first after you put the exhaust on some of the gains are from the header. so no first mod should not be header, but it should be done at the time you do the exhaust system

hope that helps clarify things for you

I have an AEM cold air intake, platinum spark plugs, high flow muffler, and I'm ordering an Af/X underdrive pulley in a couple days. Anybody know what roughly my 1/4 mile time will be? Also, do high-flow cat's really do anything, or is gutting your stock one better. By the way, I love the hood graphic adgators99.

 

[adgators99]

Thanks for the compliment on the hood graphic. I put that on before I was even a member here, but i did see that someone with a black car had a silver or white one on there hood here, so what I thought was original, someone else thought of too - still cool though (great minds think alike) just vinyl cut into the diamond shape - bought the vinyl on ebay for $6 I think

1/4 mile times are very hard to determine, every car reacts different to mods, even a rough estimate is sometimes tough.

as for cat - there are some common things , some people dump them and straight pipe it, some people get products such as megan racing high flow cat - which I heard really is just like a glasspack, never heard anyone gut the cat though. maybe someone else can give you more info on that

i see headers as pointless, there expensive with minimal gains. yes they do let it breath better, but if it made that much of a differences, the dyno would show it. thats my .02 about it. but if your strapped for cash at the moment, simply removing the air box and putting a cheap autozone filter will give you some gains. thats what i did untill i got my AEM CAI. if you have money definatly get a CAI and cat back exaust, and get the AF/X UDP like i did. pretty cheap. $140 at howell. then you can bore out your TB, high flow cat, and port out your intake mani if you got the tools. ive got a long plan for next year auto class

 

[AEMEclipse140]

If youre going all out like me and dumping over $5K in the motor alone for an all-motor setup then you should get a header i know from experience.

well ya, but i think its pointless to have as one of the first mods. plus, if you have any plans for a turbo its really pointless since you will have to loose it anyway.

how much hp did u gain after all that?

 

[GSGoinFast]

how much hp did u gain after all that?

i dunno if you misread it and thought i had the bored out TB, high flow cat, and ported intake mani, which i dont have yet, or your just wondering what i got from my CAI, Catback, and UDP? either way i dont know, i never dynoed it. my guess according to 2gnt is between 15-20? just a guess tho, no real proof.

no, no, did not misread, how much would u say u gained after the cai, catback... blah blah blah. doesnt matter about dyno, give me an estimate.

 

[realitytb]

you guys might enjoy this story

I know a guy who wants to buy an Acura Integra. he then told me he is gonna get headers that gives him 45hp. he was DEAD SERIOUS. i told him he was a god damn idiot. he then told me he was gonna turbo it out. once again, i was stunned. how dumb could this guy be? i finally told him that headers dont give you 45hp... MAYBE 4.5.... then i said if your gonna turbo, dont waste your money on headers, becuase you cant use them if you get a turbo anyway. he told me i was wrong, then cussed a bit at me, and i just laughed.

there are WAY to many idiots in this world i decided.

theres my guess

 

[EclpzLvr97]

if/when you get headers, do the 4-1....not 4-2-1....better low-end w/the 4-1.

You got that backwards there son.

 

[EclpzLvr97]

Do I? My bad....have a link handy to show me?

 

[eclipse13]

i cant find a link with the info but i do know that the less amount of backpressure, the less torque you will have, so the 4-2-1 will have more torque than the 4-1

 

[adgators99]

that is correct, 4-2-1 would be better fur us for more low end - mid range power, pacesetter makes a 4-2-1, see my new thread - asking about other manufacturers of 4-2-1 headers
