Best performance

I agree with the post above me..If i was you i would get into the ignition, Msd 6AL controll box, Msd Wires, NGK plugs and there is a coil out there by Screamin demon that is pretty good, But what i would do first is get a Performance throtle body from BBK and get a throtle body spacer then after that get Mass Air meter by Vortec and then get a Supercharger or a Turbo..Good Luck!
 
$3500 out the door, basic single turbo stup. for twin turbo, add price of a second turbo and piping. maybe $4500 max.

go turbo over supercharger every time.. only $100 more expensive than supercharger listed above, they last longer, cheaper/easier to upgrade, more torque, more power, no need for fuel upgrades unless you want more boost. plus you can install it yourself in the garage in a weekend or less
