Hi im new here and want to try asking what stuff can i put in my car to go faster, i got a 2007 pontiac grand prix base NA(this is short for Naturally Aspirated right?). when i was in yahoo they told me different things but some made no sense and there is not much parts for my car. the things i cant put in becuase of how much it costs is a supercharger and a CAMSHAFT, since the cam is like 1k to install or so i have heard. people have told me to do the basic mod of a Cold Air Intake but people argue back and forth "yes i should get" "it no i should not it wont add HP and i have a fine air box" "yes but more air is always better" i am should i get it or no and is it worth the $299? other things my buddy told me is from this site i saw which is cool ZZPerformance.com is that i should get a throttle body (or bottle someone told me) a Thermostat thing, a Downpipe and this HV3 High velocity insert. how much faster can my car go with that stuff and should i get those or something different?
To save money i want to try installing em myself that way i can figure it out and never have to take it to a mechanic or something and pay more $$$$. i was just thinking about putting in stuff that will help my car breath better like installing mufflers and a Cold Air Intake and whatever else i can do. thanks for having me here on this site i think its cool to have a place with grand prixs
