So $7k for a kit that they say is good up to 560whp. Honda destroys are cars when comparing potential between them. Isn't even remotely close.
One of the best quality kits there is. At times I wish I would have gone turbo. The power those cars make is ridiculous. At the same time I'm relieved, as I know would have spend much more money by now.
k04 on a TSI motor = $3500-4000 depending on what parts you get when you include exhaust/intake/intercooler. base k04 kit itself is 2500 from apr, which you can technically run without any other mods, but i don't think you'll see over like 260 whp without supporting mods.
Same goes for the JRSC. You can slap it on with no other mods but you won't see more than 250-260 whp. That isn't too expensive though. Is a clutch upgrade required?
