Ok I've searched around a bit. I think I am going to order the corsa 3" catback exhaust system, and the 70mm billet throttlebody set. Also which filters are better the green performance filters or K&N filters? I can't decide which. What kind of numbers would this get me? Is this a good start to modding? Thats just about my budget right now, any help would be great. Thanks

 

I think that you could just jump to a Super Charger and Turbo's, it is only 5 to 10K. NOS is another nice idea.
