Basically, when there is no boost involved and the car is tuned to its streetable limits -- S2000 -- there isn't much to be gained. Honda really did it's homework with the S2k.

Dollar per HP, S2k mods have to be about the priciest out there...

Well, the only HP mods that actually work on the S2K are FI. Everything else reduces power, or isn't measurable.
(Some people claim 2-3hp from CAI or exhaust, but I personally think thats just variances in the dyno run/heat soak/etc...)

Average cost for FI is ~$4k + VAFC (fuel management) + Tuning ($??)... I believe your out the door for about $6k, of course. The RWHP goes from an average of ~198-204RWHP to ~285-330 (depending on Turbo/SC/intercooled, and PSI/Pully size).

I suspect going FI on the RX-8 is going to be similar in cost, but I'd love to see a $1500 setup...doubtful however.

A good friend of mine has a 2000 s2k, we spent last weekend polishing and waxing our cars, comparing them and taking turns driving each others rides.

Ideal setup we agreed we be to have one of each in the garage. They really are different cars for different days.

What impresses me about the 8 is that I think it will give an s2000 a good run for it's money in an autocross. The initial grunt of the 8 being noticeably stronger (5-20 Mph) (though something may have to be done with the wheel hop issue first) and helping to compensate for it's size and weight. The 8 has flat out amazing handling for its size (you truly don't notice it's size as much when your plowing through corners.)

I can't imagine having *as* much fun in autocrossing as I had with my miata or I would in a s2000 (these cars act the part, look the part and play it well). But it's fun knowing the 8 can go to town with the best of em on an autocross course, and offer a level of sophistication that is not present in the miata or s2k (I use the word sophistication, your adjectives may vary).:: The whole package of the 8 really works well.

But ideally I'd love to have an s2k in my garage with the 8 (well honestly a turbo miata is my fantasy ;P )

Back to the main topic, i dont know what some of you guys are smoking but since I work at the dealership, and since Ive drove every damn car including the Rx8 (which i own..) and the S2k ..

I dont see how its comparable

The s2k by far has more power and will beat the rx8. If you bought the rx8 for speed, then you must be reading too far into the brochure..

Everyone knows the Rx8 is meant for the enjoyment of driving, and the stability is provides compared to other high hp/torque cars..

Though I have to say the s2k is a great fun kick *** car to drive, personally I dont like it cuz its too small and it feels like ure stuck inside.

But hey, you dont have to agree with me.. come on down and I'll let you drive them both to see for yourself

So a bit of running catless won't add too much ((
I've been lurking quite a bit but I thought I'd comment because I don't want my fellow countryman to beleive they are the cause of the worlds ills.

The above statement is untrue. The U.S. isn't foolish enough to sign a treaty that exempts 3rd world nations that are most polluting in the world. In other words they want the U.S. to be so restrictive to its own industries while at the same time they get to be exempt because they don't have the technology or the means to clean their environment. That means while those other countries that sign the "Kyoto" treaty can get away with not abiding by standards the U.S. will not. Talk about unfair.

Why on earth would the U.S. sign something that is economically harmfull while at the same time doing nothing to make these other nations clean anything. As far as polluting some of the other nations wish they had it so good.

As to the original topic. When you are talking about 1/4 mile times between the two its very close. The biggest factor is driver error and weight. On paper they are very close. If you want your RX-8 to comptete well with the S2000 in a straight line do everything you can to drop weight. You may want to find a way to lower the gear ratio also. Remove the rear seats, buy lighter parts et cetera.

I really like the RX-8

bar far has more power??? what year are you talking about. The s2k has almost identical 5-60 times as the 8?
it might have a bit of an edge, but I have driven a 2000-2002 and they don't start to move until the v-tec kicks in.
I know they improved the 2004 with lower the rpm's where the max torque kicks in, but still, the difference in power is not that huge.

I think, perfect launch to perfect launch, the S2k is 0.5 better than the 8 to 60 and the 1/4, at least comparing Car and Driver numbers on the 2 cars.

Street start is 6.9 for S2k, 7.5 for the 8.

Broker,

You are welcomed to come down here and launch the S2k and Rx8, assuming you have insurance

Our GM , John Hansen is a professional driver and great friends with Al Unser Jr. He drives every damn car we ever get in our lot.

He also agrees with what I pointed out. We also have a ex-professional S2k race driver, this guy drifts the s2k between our lots daily for fun. Both these guys have test driven for C/D/ RT/T, automobile.. Either way, dont take my word.. take theres..

Perhaps the words, "by far" is a bit exxagerated but lets not forget the notion that the S2k is faster than the Rx8. There is no debate in that, unless you have numbers to prove otherwise which i know you dont.

Again, dont take personal offense but lets be real here, the Rx8 is the lowest in the class with torque, displacement and hp. What are we arguing at ?

This thread is S2k vs Rx8, the s2k will beat the rx8 given fair factors, same driver, same weather conditions, same slicks, same track etc...

Like Ive stated many times to my customers, you dont buy the Rx8 for speed, you buy it for the handling and the smoothness is provides. The rx8 is a kick *** fun driving car, not a rocket launcher..

Of course, this is my opinion .. though I dont think its slow, but compared to a Z and so forth, there is no denying straightline, the rotary is not up to par..

Arguing that the S2K doesn't really perform until you hit VTEC is kinda silly... we launch at ~6.5-7.2k, were in VTEC, from the launch. We let the wheels slip (not the clutch, its basically a left-footed clutch drop) and stay in VTEC for the entire run. There really isn't any "ramping" up into VTEC.

I'd assume you do something similar (albiet at a lower RPM since max torque is achieved sooner on the RX-8) in the RX-8. However, wheel hop is going to be a major problem.

FWIW-- the S2K has ZERO wheel hop. They will spin (of course), but there is no bouncy-bounce. You tend to torque out to the side a little but it straightens up pretty quick.

-- Aaron
p.s. Who bought either car to race in a striaght line anyway?? If I wanted to do that I would have bought a used Vette.

Great point! and you dont get 4 doors and seating for 4 with the S2k and 350Z. A lot of S2k owners that want more room like the 8 because of the similarities. you are correct weight is the only difference between the 2 and you get to have just as much fun, besides for straight line performance you can always add more power!

Out of topic, I just test driven a 2004 NSX..

i have to say, I was close to stealing it from my company..

Great car, try it if you ever get the chance.

I have a new found respect for the RX-8. I thought it would have lossed pretty bad the other night. My friend raced an RX-8, and a 350Z down the highway. The traffic was very minimal, and they lined up and took off from about 60. From 60 to 120 they were very even. The 350Z was ahead of my friend by about three feet (literally it's front tire was about at my friend front bumper), and my friend was ahead of the RX-8 by about 5 feet. (RX-8 front wheel at about my friends back tire) They stayed almost side by side most the way. It was a cool little race. BTW I failed to mention what my friend drived until the end because I'm sure you all will say it's a lie, but he drives a new Accord coupe 6spd, and his S2000 that he traded in for the accord was faster...stock.
I think the RX-8 (like said before) isn't a dragster. It's a fun car that handles really well. I'd definitely pick it over a 350Z any day. Quite possibly over the S2K. Enjoy your cars, I wish I had one.

Nothing surprising, Accords hold a really big punch...not to be underestimated. Oh, BTW...this might fit the 'street racing' description....um...

I know...I was reading where they compared the new TL to the Accord, and they had a 5hp difference between them. Apparently it's getting a little unrated right now on the HP number. I didn't mean to sound pessimistic. It's just after being on car forums for so long, if you not praising the car that's built around the forum your always wrong. But I stand corrected.

Interesting video. As you can see, once the cars get to the straight the S2k leaves the RX8 pretty easily. The poor 8 actually gets thrashed pretty badly around the road course in that video, just to fowarn you. Not really a pretty sight

Ouch..that was almost evil..

S2000 #1, RX-8 5th place (I'm surprised it didn't come in last)... talk about a dog around the corners... I can't believe the miata didn't do better-- I suspect because that was a wide / higher-speed course... in the auto crosses I goto, Miatas do quite well.

It does go to show how well the S2K actually handles a road-course... Even the Integra out handled the RX-8. Sad indeed.

Its worth mentioning all those vehicles are 13.7-15.5 second cars (well.. except the miata, which might have been in the 16-17.5 second range).

... What funny, is that it wasn't just the S2K leaving the RX-8 behind...but EVERY car but the miata... they were laughing and waving at him as they went by.

The video is definately worth watching.

(I can laugh at this, I own both the RX-8 and S2K, so why not!). I didn't buy the rx-8 to auto-cross.. Today was snowing/raining/sleeting... which car do you think I drove?

Hehe..my 4-door sport-sedan of course!! Plus it has lots of airbags, and tractiong control thingies..and dynamic stabilitiy widigity widgets... I feel safe :-)... slow, but safe!

(Okay..its not THAT slow.. it don't compare it to the S2K....phaalease.) Stop with the "On paper it looks like" >CRAP<.

On paper I had a lot of money in world-com stock... in reality, I'm fookin' pissed!

Question

Here's another video (sorry if this one's been posted before). Here the A spec rx8 wins against the s2k. Anyone know what goes into an "A-spec" rx8?? Is it the mazdaspeed version?

Revenge battle

I found something, but I am too lazy to make sense out of it:

Extracted from: http://car.nifty.com/as/column/car_3...06024742_4.htm - Translated using http://babelfish.altavista.com/

The new concept where it loads the only rotary engine in the world, of 4 door sports was put out, tuning only of Matsuda speed was administered to, RX-8 "" "RX-8 A-spec".

As for the styling, the design which individual the chief designer of RX-8 supervised. RX-8 is the sport car which proposes the value whose "New 4door Sports for 4Adults" is new.

Cooling efficiency, CD (aerodynamic drag) with CL (lift) balance it improves well, "the front nose (12 ten thousand 9000 Yen)" it expands the air intake, guaranteeing the derived airflow to cooling type. Zero lifts (lift zero) it actualizes with the chin spoiler form which projects on left and right. "The side skirt (9 ten thousand Yen)" the body side the fact that the air which flows flows into to the underside is prevented, the function which holds down the lift change the rear is borne. "The GT type spoiler (11 ten thousand 1000 Yen)" of the angular adjustment mechanism attaching, "the rear under spoiler (9 ten thousand Yen)" of the form which sucks out the undersides style air with the multiplier effect the negative lift (down fourth) occurs on the rear. In the high-speed limits this down fourth, probably is to convey engine power to the road surface securely. Zero lifts the front and the negative lift the rear are the efficiency which is actualized for the first time with these 4 point sets, whichever becomes insufficient and may come to the point of lacking balance.

As attenuation power was strengthened "the shock absorber - (6 ten thousand 4000 Yen)" with, approximately - to 20mm ローダウン converts height, raised spring rate "sport spring set (3 ten thousand 4000 Yen)" to be compatible the handiness on the general road and the handling efficiency where the flat impression in the high-speed territory is high, also the behavior such as straddling impression and nose-dive and スクアット which when accelerating and decelerating have the stickiness was securely held down. Together, in order to raise body rigidity, "the strut bar (front 4 ten thousand 4000 Yen rear 1 ten thousand 5000 Yen)" the front and the rear with reinforces the body underside "the performance bar (6 ten thousand Yen)" and so on, チ�… - it probably becomes ideal in total to install the chassis part which ニング is done simultaneously.

Forging 1 piece structure being lightweight, 18 inch ×8.0jj of high synthesis + 40 "aluminum wheel MS-01S (26 ten thousand 4000 Yen/4 these sets)" tread enlargement of one side 10mm and total 20mm and reduction of unsprung weight are assured with the offset.

チ�…ーン of A-spec which is administered to RX-8 which has sufficiently high efficiency before the exterior exciting forum rides from, can add the expectation. Also the exhaust sound which Φ of the dual tail pipe 76.3 "the sport sound muffler (all stainless steel 8 ten thousand 2000 Yen)" the rotary engine it plays and dries being light, low smoothly from revolution turning to high revolution, feeling was good.

In addition, it has the function which the engine condition oneself is diagnosed, "the sport meter link system (price undecided)", additional meter of oil pressure, oil temperature and water temperature is set.


As for one for アテンザ "touring kit A- specifications", スポーティ it is the tuning item which assures the further potential rise of アテンザ where it can give high drivability with loading the aluminum make serial 4 cylinder engines < of the styling and new development MZR >. Being dynamic was developed up-to-date aerodynamic theory by the wind tunnel experiment which occurs repeatedly compared to it makes the good quality of the response of the aero package and the new model MZR engine be prominent which raise sport mind, the muffler which actualizes the sport sound whose being cut off is good and securely the chassis part etc. which furthermore specializes the impression of being quality of the underside of アテンザ are set. The new generation sport package, the styling of アテンザ character of running furthermore is upgraded these "touring kits A - by installing the specifications".

Was verified "the front bumper face kit (フォグランプベゼル equipped 9 ten thousand 5000 Yen)" as for design improvement of cooling efficiency is assured with wind tunnel experiment it improves aerodynamic efficiency not only, by the enlargement of the air intake. "The side skirt (5 ten thousand 6000 Yen)" the body side the air current which flows is rectified, the effect which low is shown to the design which is the sense of security has. Furthermore, the standard ria it was installed jauntily under Ra "the rear additional spoiler (carbon make 4 ten thousand Yen)", to rectify the wind which the ria jauntily passes by Ra lower part, decrease of lift and drag is assured.

Φ Of the dual tail pipe 76.3 "the sport sound muffler (9 ten thousand 8000 Yen)", good quality of the response of the new model MZR engine is made to emphasize.

As attenuation it was converted "the shock absorber - (7 ten thousand 6000 Yen)", approximately - to 20mm ローダウン it converts height strongly, raised spring rate "progressive spring set (3 ten thousand 7000 Yen)", low attenuation power when inputting which it has an influence on riding comfort that way, being cut off to be good has become the steering wheel response which has the sense of security. Connects the strut section left and right rigidly "the front strut bar (2 ten thousand 9000 Yen)" with rise to be assured body frontal rigidity, direct it can feel steering wheel feeling.

As the sense of relief at the time of sport driving can be given, comfort and キビキビ which do not impair riding comfort it was finished in the car with respect to 1 class which is compatible the travelling efficiency which can enjoy also the running which is done in the higher-order origin.

Here's what I've gathered on the mazdaspeed version so far (mostly from march issue of R/T).

-Lighter flywheel
- intake and exhasut modification
-fatter anti-roll bars
-firmer tub shocks (drops the rx8 about 3/4 inch)
-strut tower braces front/rear
-crossmember braces beneath the car
-10bhp boost in horsepower
-improvements in midrange torque

Rumors in the magazine of a hydraulic turbo version down the road and a hydrogen version by early 2007 (hybrid, flip a switch for hydrogen or back to gas guzzling mode).

Sounds like fun stuff on the horizon

it would be damn close, but i would have to go with s2000.

the rx8 isn't meant for drag racing. good question though.
