enzolat: If you're really disappointed in the throttle response and it is not resolved by re-setting the PCM as I mentioned before, you're probably just feeling the effects of a 3,000 lb 218 hp car. For less than $1,500 dollars you can turn it into something that will let you experience the pull that your S2000 had and give you 237 hp at the crank.

Get the 3" dual intakes, I spoke about from forum member SASKINS. Find a good performance muffler shop and have them cut the resonator out and give you a dual straight thru Magnaflow exhaust. Then have a custom chip tuning done for your ECU (Upsolute or PowerChip). Fill the tank with 4 gallons of 100 octane fuel, 1 gallon of Klotz COXOC, then go find an S2000 to race... You'll blow his doors off... This is the best way (cheapest) to get the ponies you're looking for... Good luck on your mods... And take it to the track when you race!!!
