Can you tell me what the most power ever put down on a STOCK BLOCK f22 or f20c has been?
Stoopid Fast racing has put down over 700 on stock k20 and k24 blocks...
And except for cams is correct...but this makes a HUGE difference!

Lets compare the number of all motor s2k's running 12's to all motor rsx's running 12's....RSX by far, mods are cheaper, and its more mod friendly.

I love my s2k, but i just have some issues with it . I havent had a problem with any RSX's in a race before either...but their are more fast RSX's than their are S2000s for sure.

 

It still shocks and upsets me that the S2k is such a heavy pig for what it is. The Miata has gone the bloated route, too, these days.

Is it really that difficult to build a sub-2,500lb. roadster?

 

I went from a 2005 RSX Type S to an AP2 S2000.

To answer your questions...

To me, the driveability is better in the S. Of course you are going to have road noise, it's a convertible... but this is an enthusiast's car and is meant to have fun, not to reduce road noise and look fancy.

The torque on the AP2s will be a noticeable difference from the Type S... figure you are going from around 140 to about 162. The gearing though is what really makes up the difference. Finally, if you think the Type S screams in Vtec, the S2000 will be a loud car for you. Stock they are about as loud as a Type S with an intake. The S2000 is in another league, and if you get one, you will soon find out why.

 

Jason (St00pid) tuned my old car (RSX) and does have a lot of experience tuning the K series and F series. Yes, he has extracted that much power from the K series engine, but how long do they last? If you want to play that game, let's compare the number of turbo failures on the K series and the number of failures on the F series. The K series with a turbo in a lot of cases is a bomb waiting to explode. Phil, a guy here who has the highest output supercharged S2000 has been making over 500 rwhp for several years without one problem.

The K series does respond well to mods, but so does the F series... it just has to be done the right way. If you slap on another duel exhaust, you are not going to gain much. If you go single, it has just as good gains, if not better than a Type S cat back upgrade. In fact, K series with I/RH/E and Kpro dyno tuned is good for between 200 and 210 whp. F Series with I/H/E and simple VAFC is good for 220-230 rwhp.

My point is there is a lot of ignorance out there regarding the F series. I am not saying you are one of them, because you sound like you know what you are talking about. I just get tired of going to clubrsx and reading about how an RSX with just a CAI put car lengths on an S2000.

The K series is an amazing engine... but so is the F series.

 

If you want to build something that isn't pint sized, has an extremely high level of structural rigidity, and impeccable safety specs..then yes, it is hard to build a sub-2500 pound roadster.

If they could, they would. It would probably be a lot more expensive too, due to extensive use of aluminum.

The S2K is a lightweight relative to most cars on the road these days.

 

 

Very true...in fact, your post was so inspirational it makes me wanna keep my car and NOT get a RSX haha, because i know the mentality on CRSX...

I think my main problem is just getting burnt out on driving the S everyday...i have my evo too, but thats not much better haha. i mean it has way more room, but the suspension will chatter your teeth away.

To the OT, its a tough choice, but aint nothing like having the top down on a nice sunday drive.

 

It's really something you'll have to get used to, but plenty of people here daily drive their S's with no problem. I'd say the torque is noticeable, yes. Also, vtec > vtech

You'll be pleased with the radius, though the RSX's wasn't all that bad was it?

With the soft top, driving on highways, the noise can get to you. You'll definitely have to raise your voice a tad when talking to your passenger. Top down, this problem goes way up. But who cares? I have too much damn fun driving to engage in conversation with my passengers anyway...

As far as the transmission, I always read and heard about how great the RSX's tranny was. It is my opinion that compared to the S, the RSX feels like crap; like shiftin gwith a wooden spoon in a bucket of cold oatmeal (I'm exaggerating here, but really, the S2k's transmission is top notch)

 

to the original poster. its very simple. the s2000 is faster, more fun, harsher, louder, less practical.
i've driven many rsx-s. it is a good lil car for its segment. its very practical and reliable. the s2000 is a diff animal. it is a specialty vehicle that can be treated as daily driver if it needs to be.
imo, stop worrying about the differences. once u get in the car, u will know if it is for you or not. i would say within 15 min test drive, u'd know. it's a love it or hate it car. if you r too big, if u need practicality, u wont love it.
the mod question that most of the internet folks argue about doesn't come into play for 80% of the people out there. u can always out mod someone, on any 2 cars so there's no pt in arguing.
its good to prepare while u r reading on the internet. but with the s2k, there's no substitute for a test drive. even if u r a passenger, u wont really know what a s2000 is like.
after first 2 times of driving the ap1 s2k, i couldnt stop thinkin about it. i drove a $50k lexus coupe at the time and all i could think about was this honda roadster. i'd come on this board & read other ppl's experiences just to reminisce about my limited experience. 3 years later, when i got rid of the lexus, there was just 1 car for me and i went out and got it
