Yes, BY TODAY"S STANDARD the NA's are not fast. They are after all mid 90's technology. But when they made their debut in 2003, (even though they were using a 7 year old platform) they performed pretty well when compared to the competion.
As we all know, the performance never changed in the 5 production years it was built, so yes it is and was sort of "frozen in time " so to speak.
For the record: Per Road & Track Road Tests.

04, Crossfire 6sd. 14.7 sec.
04, Audi TT 3.2 Quattro,14.7 sec.
04, Mazda RX8, 14.6 sec.
03, Porsche Boxter, 14.6 sec.
05, Nissan 350 Z, 14.1 sec.
05, BMW Z4 3.0i, 14.1 sec.
05, Honda, S2K, 13.9 sec.
04, Honda Accord EX-V6 Coupe, 14.8 sec.

By the way, one thing that should be pointed out, ALL the above mentioned cars had a final drive ratio of 3.44:1 or better. The RX8 had a 4.44:1, the Audi a 4.20:1. and the S2K with a 4.10:1.
Compared to the 3.27:1 Autobahn Crusing Gear the Crossfire was stuck with, personally I think it performed admirably.
I don't think I'd be going too far out on a limb if I said that a set of 4.10 gears in the back of a Crossfire would easily cut a 1/2 sec off its 1/4 mile times, and quite possibly break into the 13's as well.
As for the modded SRT6's, which are now in the mid 11's, 10's would surely be a possibility using 4.10 gears.
Hondas are fantastic cars. I've owned over15 different models in the last 30 years. Mostly all Civics, one Accord, and a 3 CRX's. If the S2K had come out with a coupe, and a little better looking body, I may very well have purchased one, that is if I could have fit in it. I tried on a roadster in the showroom once, and it was a no go.
