I was wondering if anyone knew about how much it would cost to take a stock 03/04 cobra to be putting out 500-550 horsepower and torque. Going to be buying one in about 6 months and wanted to know how much ill be looking to spend. Ill be taking it to modular power house in Atlanta to get it done cause I dont trust myself to do most of it. If anyone here has done this either with the same place or any performance shop and is around 500 to 550 or more power let me know about how much everything cost with labor. Thanks everyone
