^^^ ok, it's obvious that you really have no idea about modding cars so I'll help you out here.. Yes, forced induction (supercharging or turbo) costs a lot of money, you need a lot of supporting parts to make it run safely... for 1K in mods, I would do an intake (kn slip in as no other options exist as of now) exhaust, strut bar.. that's it, that's all that 1K buys you.. and the hp will be around 15.. that's it..
and no, that ebay link of that intake is absolute garbage... there's no magic chip that gives 50 hp or some tornado intake that adds 15+ hp, or liquid additive..
I suggest you go to the 2nd gen mods section of the forum and look around, yes read some threads.. you will actually learn a lot as a lot has been discussed already..
