what would i expect to spend

it just depends on what you want to do, and what products you want to go with.
for example, my 3.73 gears, with all the new fluids and hardware plus lifetime warranty on the work was $550 dollars. My BBK Plenum, BBK Throttle Body, and BBK cold air intake was about $500 dollars total and i installed them myself, and its pretty easy if u take a look at it. its really not that hard. you can also do underdrive pullies which will run you about 150 for parts and labor. and as far as exhaust, you already have exhaust, and my predator tuner with a custom tune was about $500 dollars, $370 for the tuner, and $130 to put her on the dyno. I also have a cobra brake upgrade which was 1k total with installation and warranty. as far as nos or a supercharger goes, ur looking at big bucks. not so much for nos, you can get that in your car with a tune for about 1k, and for a supercharger, with a tune, id say your looking at about 4k out the door. Other than the regular bolt ons, if that doesnt tickle your fancy, build the motor......
