I have drivin' a Stock Type S before. They are nice, but the thing that Honda did when building them, was building them for the aftermarket. They built them so that with minimal mods the car would peform a 100 percent better. With onyl an Intake you can hear and feel a difference. The biggest mod to an RSX type S is the K Pro, I have seen gains upwards of 30 HP, with the right mods attatched to it. Like I said you can spend 15,000 for an RSX type S and put on intake, exhaust, race header, and K Pro, Kpro being the best mod for it. All STOCK cars feel kind of sluggish, with the eception of the STI or EVO 8. But when they built the car they built it for the aftermarket. Not for the grandma down the street. Also when they tuned the ECU for the car they did not max it out, as they wanted good fuel economy too. So jsut a simple ECU Reflash will give nice gains that you can feel. I don't do reflash, If it was me it would be K Pro or bust. II would have to drive that car to see if it was a LEMON. But then agian it very well could be. I have seen to BONE STOCK RSX type S's run a 1/4 mile, the driver switch to each car so it was accurate and one rsx was faster than the other. I like to cal those cars ON CRACK, because there is no reason one car should perform better than the other, but they do and I have seen it.
Kinda of off topic here, but My friend had a 350Z with Intake and Apexi SAFC, and he ran a 13.0 1/4. His car was on crack. U get my drift tho.
