im so confused. if the S did have ivtec, what would it feel like? would it be different than if you had a vtec controller and lowered the vtec engagement point?

 

you guys may be missing the point.




S2000 = 9,000 RPM rev-happy car which is fun to redline every gear and is easy to hold high-RPMs in track turns.

i-VTEC engines = ability to adjust where most power is made based upon driving style. i.e., if you don't rev high, more power is available down low, if you rev high, more power available up high.



S2000 engine was designed to rev high. Therefore, no intent to create gobs of power down low. When was the last time an F1 car was designed to have great "mid-range"? You beat this car everytime to redline and that's it. The way Honda designed the S2000, i-VTEC (if it had it), would stay up high at all times.

 

Who cares if you can "easily mod" an RSXS to 200 whp? I mean, really guys... You're all upset because you can magically add 30 whp with the i/rh/e/hondata combo? With the RSXS, you have to add all that just to make it comparable to the F20C STOCK. A 70mm single outlet, CAI, and VAFC should net you 15-20 wheel horsepower. If you're concerned about those RSXS drivers out there, add this combo to your S2K and you're back in the game. I think people say the S isn't modded easily is because they're spending 7-800 dollars on a dual exhaust system and upset because they're only netting 3hp over stock. It's these "tuners" that are adding carbon fiber hoods and trunks, dual exhausts, and an intake and are upset about the car's lack of tunability. Well, SPEND YOUR MONEY WHERE IT COUNTS THEN. Stop complaining about how you like the 'look' of a dual exhaust yet are upset about no extra power. Does the RSXS have dual exhaust? NO.

You're all pissed off because you can 'mod' a car to be comparable to another stock. What a crock of sh|t. This is how it is with every car company.

Remember, BOTH engines are 2.0 litre. The F20C is still making tons more power, and the RSX drivers are having to spend some money just to make up the power. If you're upset about this, do some SMART mods, like the combo I just mentioned, or a new gearset, or sell your car and get a "SUPER MONSTER 10K RSX" (I think hondata makes it 8600 anyway) and I can then laugh at you because you're still FWD and I'm still faster.

That is all.

 

and BTW. the record for a s2000 is 11.1.....check the FI forum, there is a video of that run too.

 

I'm not really complaining about the S2000 engine, but it seems to me that K-series engine could have made more hp stock, but Honda de-tuned it so as not to compete with S2000. The JDM Integra Type-R makes 220hp at the crank. I think if honda let it breathe better it could make 240hp. But then japanese buyers would have a tougher time deciding between the two...although very different cars, a lot of people just want to be "fast".

Not really knowing anything about engine design, can someone explain to me why the F20c is that much better than a K20A1? I/H/E/Toda Kit makes 230whp...I'm not sure if I've heard of a S2000 making close to that NA (at 2.0L). Yes, I could give a crap what tuner's do, but isn't that a somewhat accurate depiction of potential? Yes, there is drivetrain loss in the S2000, but 230 whp in a FWD would translate to more than 240 at the crank.

Again, in no way am I saying that the RSX is a better car or that the K20 is definitively a better engine. I'm just wondering if the K20 is a better design since a) it can make more power and b) it came out 2 years after the F20 did.

 

Maybe I missed it as I scanned through the posts.. but the ITR K motor has 220 hp stock.. and I'm pretty sure on the FF platform they are making about the same whp as an S2K. Who cares though.. they are both great motors in two great cars. This whole debate seems pretty ridiculous to me.

 

So, what does it take to make over 250whp on the S2000? Probably would need engine management, some type of valvetrain upgrades, custom grind cams to take advantage of the more revs, individual throttle bodies...right? Is there much to be gained with headwork? From what I've heard the S2000 head is great stock, but is there room for improvement? Probably would also be necessary to go with higher compression to keep those radical cams happy...

 

For all you bitching about K-Series vs F-Series, just go stick the K-Series in your Ariel Atom.


Then you have a faster car yada-yada. In the meantime find an S2000 and appreciate it as much as you can.

 

I think I agree with afwfjustin here. You have to remember that the S (properly driven) is a whole second faster stock in a straight line. That is a big differance.

Yes you can mod the RSX-S (meaning the k20) to run that time without a huge amount of mods, but that is why it is called modding.

Like many others have said, the RSX (without forced induction) pretty much hits a wall at that point. It's harder to keep squeezing out more all-motor power.

So what you have now is the S2000 and a modded RSX-S hitting a wall at somewhere near each other.

I'd imagine the RSX-S all motor with the normal easy mods (nothing elaborate here like a 10k redline) with I/H/E/Hondata should hit about a stock s2000 time. Then if you squeeze a little more power out of it you might get into the lower 13's. You can do the same thing with the s2000. At that point they both just about hit a wall and can't go further without F/I.

So you can't really complain if RSX-S can be made to run similiar to the S2000 with lots of mods. I think the complaint would be that you can't make the s2000 much faster once the RSX-S reaches it. What you have to realize is the all-motoring tuning of a 4 cylinder is only going to go so far without forced induction (turbo, s/c, nitrious, etc).

I think low 13's out of either of the cars is pretty amazing for an n/a 2.0L 4 banger. If you really want more power after that your next mod (if staying all motor) should be 2 more cylinders (or 1 if you buy a volvo, lol).

 

Good grief.. quit using the RSX-S as the comparison... if your going to use the K motor use the best version of it. You people kill me...
