Ok the drag 3 kit and revhard stage 2 kit are almost identical. The rev hard has painted steel piping where as the drag has chrome. RH uses a msd fuel pump whereas drag uses an airtex. RH has a vortech bov and drag uses a hks ssq. The revhard has an oversized FMIC vs drag's large one. Both use their respective manifolds and both use a t3/t04e turbo. Also drag's kit comes with an intake pipe and filter whereas RH uses a mess screen which will damage the fins on your turbo over time. Now tell me what makes RH's turbo kit so good and what would cause it to make anywhere near twice as much hp as drag's kit. Both kits cost relatively the same. The stage 3 isnt even a complete kit. Its meant to run with a fuel management system that is not included and still needs injectors. Keep your mouth shut and stop spewing out misinformation.
