it's not very easy to be honest.
High Flow Cat / midpipe might get you a few horses. (6-8)
Intake / exhaust might get you another 2-5

cheapest way to get a real 10 to 15 would be NoS. You'll get a lot more then 10 or 15, but it's the cheapest way.

Exhaust, intake, pullies, cat... all together they might get you 15. total cost will easily be twice what you'd pay for NoS.

Lose weight in the car - THAT would be the cheapest.

Gain power or lose weight = same thing.

JK, take things out of your car - this will lighten it; like the backseat if you're hard core.

Lighter wheels - 2 piece rotors are winners too.

There's also a handling benefit to reducing unsprung weight

The law is kinda funky here in IA... Its totally legal to have nitrous in your car... its only illegal if the nitrous is hooked up ... so if you disconnect the line from the bottle... legal... connect it to the bottle... illegal. Who thinks this **** up?

You can have a gun in your car too. As long as it's in the glove compartment or the truck.

That way they know you can't use it.

Same principle. Freedom to have it, just can't use it.

but you can not have the gun and the bullets both in the glove box... so why the tank and the line both in the trunk where it can be connected .... not that i am complaining any, its jsut obvious that yoru using it and more then likely on the street... i know the excuse woudl be that its only used at the track, but usually in most cars the bottle is always connected anyway

A lower rear gear won't give you more power, but it will improve your acceleration somewhat and make the car more responsive, at the expense of top speed. And highway mpg. But I don't think I'd call it cheap. Probably cost you 700 for the FEED gear, 500 to have Mazmart do a rebuilt diff for you (plus core deposit), and then installation if you aren't comfortable doing it yourself. If you have a buddy who is a mechanic you might be able to get it done reasonable. Not sure what a differential swap would be at standard shop rates.

here in CA, if u have a remote bottle opener, when u turn it off, and ur bottle isn't open, they will let u go cus the nitrous is not technically "useable" unless the bottle is open
