idea's for cheap and easy modifications

i just got my 96 firebird a few months ago and i don't have a lot of cash so i wanted to know if anyone had any suggestions for cheap and easy ways to upgrade my 3.8l V6 with a little more power until i can save up for some bigger modifications, thanks for any suggestions. :1zhelp:

normal bolt ons: cold air, cat back, headers, gears, underdrive pulleys,

K&N air filter. all these bolt ons wont add a ton. but you should feel a difference.

yah well most bolt ons add from 5-15hp but the headers and cat back will add about 30hp together then the cold air another 10-15, underdrive pulleys another 5-10 and then gears are just more accelaration
