I very seriously hope not. This would ruin the S2k.

Didn't we JUST have the AP1 vs. AP2 argument yesterday?

The fact of the matter is, the AP2 puts down between 5-9whp more than the AP1... eleventybillion dyno days with S2K groups have proven this time and time again. And they are dead even as far as speed/acceleration is concerned.
there ya go... let's end it at that....

I watched the interview with Bill from www.vtec.net and the Project Manager of the RDX prototype project and he asked him about the block used in the RDX and it is not anything Honda is currently using. He specifically asked if it was a K20 variation, and it is not. He stated they designed a new block because the others did not have the long term durability they wanted. This does not mean you can not turbo a K, B or F block Honda motor, just what they did in the design process.

If you visit the article written in Road and Track back in March 2005, the AP2 S2000 did very well against and came in 5th in front of the SLK350 (newer body style), the 350Z, the Z4 3.0i and the Dodge Viper. They went as far as to say the S2000 had the best shifter of any production car made today. It would have also beaten the Lotus Elise if it were not for the fact the Elise is a nicer all out sports car in there sports car tests. The Top Gear customer survey has seen it in 1st place 2 of the last 3 years, out of 120+ cars and 50,000+ surveys. They were even so good, the SCCA bumped them from B Stock to A stock because they were wining so much (the AP1s), and they are still dominating the A stock class in nationals. HP is not everything, the Mazda RX8 cleaned up the B stock class this year, which included 350Zs and G35s.

I am perfectly happy with my S2000. I have wanted one since they came out and now have one.

What is wrong with just turbocharging the engine we have?

I see your points, very good one's at that... But I wouldnt take shawn church finding worth a dime... THis is the same guy who has people believing that a stock ap2 s2k can dyn in at 235 rwhp when the car only makes 240 crank power.
Well Shawn Church doesn't make things up. He never has in the 4 years I have known him, and he has no reason to.

He has probably tuned more S2000's that you will have an opportunity to drive in your lifetime. Among the most elite and reputable S2000 tuners in the US if not the world.
It's a 900 mile round trip from the bay area and several of us go to him exclusively.

Honda under-rated the crank hp on the F22.

My '02 F20C did 218 rwhp NA on his dyno. So about 10% drivetrain loss.
Which car made 235 rwhp? What mods and redline?

Dynos don't lie, manufacturers do.

Hey... sorry I forgot to get back to you on the valve adjustment, just busy. Any ways, look a few pages back. The one on the 06 dyno, think it got locked... I didn't say he was a bad tuner, just some of his number's are bs... Liek a stock 06 comin in at 235 rwhp, and church being quoted on that being average for an f22....

At our dyno day a few months ago not on ap2 broke 206 I believe....

I'm not sure about the 235whp, but I do believe that the 2.2L motors are putting down more power than published by Honda marketing.
Which explains why in three years we have not seen one run a faster times than the AP1?

Actually now to think about it, maybe it is possible for the F22 to put 230+ to the ground. Let's just suggest that at the crank the motor is really putting out 260 at peak (not too much of a stretch to believe, right?).
Are you ****ing kidding? Don't you think that if this was the case -- maybe one or two would be running faster 1/4 miles than the AP1's ....

The fact of the matter is, the AP2 puts down between 5-9whp more than the AP1
The fact of the matter is -- that dyno days with cars from various years on the same dyno under the same conditions disprove that myth. I know you AP2 guys want to believe that you gained something for the lowered redline -- but the numbers and the 1/4 times prove you didn't.

My '02 F20C did 218 rwhp NA on his dyno. So about 10% drivetrain loss.

Once again the Shawn Church vtec.net bullshit machine in action. The simple fact that people do not understand the various types of dynos and how corrections are applied to make numbers larger simply ****ing amazes me. Church's dyno is known to read high -- they are generally referred to as crank dynos ... you can figure out why ...

Dynos don't lie, manufacturers do.
No but idiots who misinterpret dyno numbers do -- to themselves.
