I would just get your gen 3 ported. I have a N* on mine, but it has been a lot of hassle to get it working properly. if I was going to do it again I would get the supercharger case inlet ported to 72 mm and put a zzp HVTB on it. speed daddy headers are a good way to go, but it is a good idea to cut out the interlock flex section and weld in a shorter one. the speed daddy headers downpipe drops down a bit too low for me to be comfortable with.
