2002 GT - headers, UD pulley, 75mm throttle body and plenum

[dumbmick]

Hi,
I'm considering instaling the above 4 mods to my 02 GT. I know I'll have to get a custom tune, but I was wondering in general if folks think the above mods are worth the investment from a cost/benefit analysis. Benefit in this case is obviously RWHP. I don't have the time/money to go either super-charged or turbo.
Thanks,
Tom

Thats a pretty good combo, should wake that 2V up nicely.

Hey Guys,
I just ran into a what I think is a steal for brand-new, in the box parts consisting of
bbk mid size headers, 75mm tb & plenum for $500 total. I honestly haven't researched
this enough to know whether this is just stupid low pricing or just so so. Advice?
