nitrous is probably the most bang for your buck if you wanna take that route

Nitrous is the biggest bang for the buck.

I have almost the same mods as you have....Although I have a 75mm TB, And a Trick Flow U.P...and an intake spacer....But I would say go with Nitrous if your really looking for a noticable difference in your ride....Just do it right and be safe with it

if you have the stock intake manifold i would not do nitrous. go LTs or an intake

Nitrous is a good mod for the money, however a new manifold with t/b+plenum will get you some nice power gains, not what nitrous will but still good gains
