Everything Joe said is correct, but I think that Sleepy is talking about putting a SC on his RSX.

I don't know anything about the RSX kits, if there are any. Just do the research to see what the RSX kit comes with. Supercharging a car is considered to be one of the safer ways to mod a car. At least one dealership in Houston installs SCs on brand new Civics and sells them that way, full warranty. Just ask around, see what you turn up.

As for the AEM, it's pretty easy to sell a used CAI. I did the same thing, I sold my CAI one I did the SC. The few hundred $$ that I lost was nothing compared to the benefit I had with the CAI.
