So all that stuff I have been reading about how reliable the stillen SC is bs? I get that if you go to their website they just want to sell their stuff (just like everybody else), but out of all the kits that I have looked into they seem to be the mildest and more reliable. The only thing that I read about their kit not being reliable might be the pulleys because they use plastic ones. So does anybody out there have a 13' 370z with around 500hp without going the Turbo way? And if so, how heavy are the mods? I mean 332hp is stock. Is it really that hard to get about 180hp more with a stillen kit, exhaust and a tune?. The tune that stillen offers is around 40hp. There are quite a few exhausts for our platform that will give you around 15hp maybe 18hp. That's 55 to 60hp right there. The stillen kit will not give you 120hp more? I'm I totally wrong about this numbers? I have been reading numerous threads and reports and product reviews and those numbers do not sound crazy to me. Please feel free to chime in. As always, happy motoring
