A great place to start would be rsx-performance.com these guys know there stuff. They can probably point you in the right direction.

Good Luck

With these upgrades AEM2 and exhaust with the ecu you should expect at least 190+ at the tires. The baseline numbers on the rsx-s are different some people get 160hp some get as much as 173. I got 170.4 to the tires bone stock on a 248c dynojet with 19k miles on the car.
