just an estimate how much would it cost to install

pulleys
intake
front rear sway bars
lowering springs
exhaust

and

NOS

Well even if your not handy the intake,exhaust and sway bars you can do yourself they are pretty straight forward. Aslo so if you are getting lowering springs also get better shocks

well, if I was around a case of beer and dinner....

the intake, you can do yourself. it is really easy and im sure it comes with instuctions..
