Based on the minimal mods I have in my sig, what would be a good power adder to go with next? I am still in college and am on a budget. I want something that is fairly inexpensive and will get me some performance gains. I want to keep it naturally aspirated as well. Turbos, SCs, and Nitrous are out of the question. Any ideas??

 

H/C/I

 

Gears, 500 bucks or less for parts and install.

 

I would say gears too .I put 3.73 ford gears in mine with new seals and gear oil it cost me around $800.Thats not added hp but it will sure feel like 50 more hp You'll be alot faster in a quarter mile or so.....
