If all of your mods are installed, it sounds to me lik3 you should have him.
I read in a few magazines (reminder most magazines over doo there stats) that a Cold air kit alone on the RSX-S netted anywhere between 7 and 15 hp to the wheels, depending on the brand....a rsx with exahust too....i don;t know how much more it would be....i do remember though that the Cold Air only netted at most 7lb of torque.
These cars are no slouches by any means....yes they don;t have as much torque that the duratec makes, but they make up with it by being a little lighter.
what i do know is that at SAC raceway, i lost to an RSX.
I had (my 2.5 liter) intake, heatshield, exahust, quaife, Spec 2 clutch...all he had was intake and exahust.
my car compared to his was a drivers race...and he obviously was a better driver.
Id say race him, and see what happens, and let usknow the outcome.
