Adding hp to a 1995 Firebird

I just bought a base 1995 firebird. I would like to know what aftermarket products i should buy in order to up the Horsepower. Also i would like to know how much gain in horsepower i should expect for certain aftermarket products; ie. Intake, exhaust. Last i would like to know which products provide the best performance for the price. Thanks

Torque is more important then HP.

A Base 95 Firebird is a V6 right, well how about an engine swap? If that is out of the question I'm sure cam/headers + true dual exhaust will help a bit.

I'm assuming its the V6. Its somewhat pointless to build a V6 because by the time you get as quick as an LT1, you could've just bought an LT1 in the first place.
