first off hahn kit is just a waste of money. the fpr that comes with it is total crap so you will end up spending somewhere around $200 for a vortech sfmu. also comes with rubber fuel lines which u will change to ss. turbo you will eventually change if you plan on boosting more, however their manifolds are one of the best. intercooler and piping is very good too.. honestly with the $3500 ur gona spend on a hahn kit you can put together a much much better kit with all the best brand name parts and alot of extras . unless ofcourse u dont feel like doing as much research and just want to buy a kit and have your mechanic install, i'd go with the star. but your gona have to find someone who already has one for sale because star stopped making those kits a long time ago i think. or you could always offer someone on this website $3500 to put together a kit for you, im sure no one would turn down an offer like that :)
if you plan on doing some research use the search button and if you can't find what your looking for, change the "search which fields" to subject only. <-- trust me this is very useful and will save you alot of time.
