intakes CAN make power. as do exhausts. it might not be much, but it does.

To everyone who has positively participated in this thread, thank you. It is greatly appreciated. This was a thread generated for the basic rx8 noobs who just want to get a basic idea on what modifcations could be helpful on their path to building a ballin' car. ( I will gladly admit I am a noob when it comes to the whole rotary scene, I've only had the car for 6 months...)

To those of you who mocked me thanks... you are a real fellow for taking the time out of your day to TRY and make someone try to feel like an idiot, when in all reality you just looked like a **** poor excuse of a civilized human being. lol I'll be sure to get the flame stickers ;P


And for the CAI, the AEM website CLAIMS (as I had mentioned in my first post) to have added an extra 8 hp, which I know is probably from the best dyno test results they got... Unfortunately, I have not ran my car on a dyno when I first bought it stock, and I won't bother wasting my money on dyno time for just a CAI. I'd rather wait until I build my car up a bit more... My experience with the AEM CAI just seemed to allow my car to breath much better, and add a tiny kick to how much faster the car responded...

I certainly will look into buying a midpipe, hopefully at a reasonable price, and suspension mods would probably rock considering the cars handling stock is already pretty decent.


With the AFE short shifter besides the way it feels when shifting, would that decrease shift time resulting in quicker times?

My humble opinion - forget turbos - forget exhausts - forget drops and shock. Go buy some clear corners. It is the single best enhancement to the car I've seen, and it's $75 (throw some white LEDs in there). I never thought it'd could be a big difference until I bought my own set about a month ago and popped them on. It's like night and day.

Ironic that the guy above you has 'amber corners ftw' in his sig lol.

I beleive the shor shifter gets you slightly quicker acceleration that you can feel. i imagine that translates to quicker times, though i wouldn't be caught dead on a drag strip. boring,.

It's not slow as ****, you just need to learn how to drive it properly...

^ slow as **** on straights i would agree. Even if you drove perfectly 100% , its still slow , if a camry beats you , its slow

nadaxsurf720

well i certainly wouldnt go as far as saying a camry has ever beaten me.. with the intake after a ton of runs with a 2007 chevy cobalt ss only pulls by a few inches. I couldnt imagine a camry being able to come close to competing with a cobalt. but **** i suppose it could work haha clear corners sound nice. and on the straights the rx8 doesnt perform as quick as id like it to... autox is where it definitely seems to be for these cars.

Nice, more childish comments. How do you know how I drive (topgear8)? How about NASA participation for the past 9 years. Racing in Miata spec, HPDE classes, a racing license, over 25 cars and a few years on my belt. 2 3rd gen RX7's, one with a 383 LT1 (hence I feel the RX8 is a DOG.....), an Evo, a mazdaspeed6, hell a GTI that was faster than the 8, 9 mustangs, a 924, 2 1st gen RX7s, an integra, and some more cars...... get yourself a new set of references. I am merely upset that someone is trying to get valuable information to save time and money and is asking for help yet a bunch of baffoons answer with corner light suggestions. Simple request, what mods help? By how much? your impressions?
Those would be useful replies..

Oh and please do come by Denver so we can see how you can drive. I'm available. I"ll even drive my wife's Honda pilot just to give you a head start....

Calm down here...based on your track record, yes, the Rx8 is a Dog on a straight line.

Its basically a big Miata with hard top...or S2k without the VTEC :P

It drives beautifully tho. And on a track with not a lot of long straights, it can hold itself against much more expensive cars.

Anyway, back to your question.
A)Replacing your cat with a high-flow one / run catless race pipe will give you the most significant gain on a N/A Rx8. Problem is that its definitely illegal and it STINKS.

Verified hp: 8+hp AT LEAST

B)The catback exhaust will give you the second most gain by
1)reducing weight if you got mazdaspeed/other lightweight ones
2)better flowing exhaust and getting the distinct rotary sound back

For this two reasons alone, you should get this first even without a cat you will gain more horsepower.

Verified hp: 5+hp AT MOST

C)AccessPort tuned by experienced vendors
This will give you a full control of the PCM. If you dare to learn the programming, you can even change the A/F ratio, pump rate, etc at will. HOWEVER, it cost a lot and if you don't tune it yourself, you have have difficulties getting updates from our famous MazdaManic guy, who is the best here on tuning these - he don't have much time.

Verrified hp: Depends on application. On my rx8, it goes up freakin 2hp at higher rpm. DYNO Verified.

D)AEM / Mazdaspeed CAI; Racing Beat Revi intake and duct; KN Filter with removed screens.
This will give you a cool intake sound, but frankly not much else. Racing Beat's setup is widely acknowledged as the most hp gain.

Verified hp: Check Racing Beat website...I think at least 2.5hp+?

E)Pullies, flywheel etc...
Well these dont increase your hp but reduced load/weight and make your engine rev faster and more responsive. I assume you definitely knows about these...

You can do a search on these topics and see detailed analysis. Good luck.

nadaxsurf720

really??!!? accessport only gives you an extra 2.5 hp?? is that even worth it? the system itself is like 600 bucks... is that just with the pre programmed settings?


and can u smell the exhaust fumes from inside the car if you run a highflow catless race pipe? I want a loud *** exhaust, but not if its going to annoy me by the smell while driving it lol

excellent info kafka much appriciated!

ya for those of you who keep saying "all the guy is asking for is help" blah blah blah

There are THOUSANDS of noobs on this website everyday asking the same questions. We actually got smart and made a sticky thread and lots of other threads that already discuss the EXACT topic. Also there is a search button on the top for those who have not familiarized themselves with the site layout. Try it one day.

I think registration to the site should have a introduction waiver explaining this. Just my 2 cents..

I honestly think that saving the money from a lot of the "cheaper" mods and investing in a decent suspension is the way to go. It will do more for you than most of the other mods combined....well, as long as you're not dragging. The long and short of it is, you usually get what you pay for. So, if it's the twisties you're interested in, lay it down on the suspension and use what you have left over for a few small "power" mods or better yet, a light-weight flywheel.

Don't you miss turbos? Gaining 20+ hp off of a catback.........................

636

^ yeah or a bigger displacement engine . But of course that is taboo around here XD....or so it seems. Imo accessport free's up some horsepower and makes the car run better with the mods you have. Also its required once you go FI , so i find it a good buy when N/A also. Really depends on your goals for the car...

nadaxsurf720

thank you very much for all of your help. With the info I have now gotten I will start to search on google and stop asking u guys now that i know what to look for. once again everyone, thank you.

OBX exhaust $300-bought becuase not too many ppl had it and liked the sound not too loud
Wheels$900 first set $700 second set..first set damaged and don't make anymore so got different ones.

HID conversion-like 90 bucks better visibility
sound system-550 or so don't quite remember

Once again this thread is a perfect reason why the "post new thread" button should only appear on the search results page.
