I've got an 02 Vette. No mods other than a cold air intake and a tune.

Is their any HP to be gained by replacing the Intake Manifold and/or Throttle body, IF no other mods are planned. I'm guessing it would pay off with heads and a cam and/or headers,but with an otherwise stock engine, does a FAST intake or similar free up any additonal ponies?

Start with basic bolt ons like headers and cat back exhaust.

A FAST intake will gain over LS6, how much depends on what else is done to the car.

With a stock engine i'd stay with the ls6.

The manifold shootout atricle I saw, looked like no big benefit
on a stock motor (LS6 vs FAST) but the big manifold pulled
away from the rest once heads / cam were in the picture.

If you're doing it sequentially on a budget I'd do the exhaust
first, then heads / cam, then intake.

the fast wont help you much with basic minor bolt-ons . . . but with heads cam it will, so will the new weiand

Stick with the LS6 and add some headers/catback. Look on the corvette forum for some used headers and catback because they're EXPENSIVE
