Hello I was just fiddling around on Fit freak and noticed how you would like the HKS turbo kit.... I would say no go dude, I did not see any significant gains with it. Check out Car and Driver they did a side by side FIT comparison. Took a 2007 from HKS with the turbo, suspension and all (27,000 dollar car in all now) and my 2009 is just as fast. Secondly when buying my 2009 I saw a used 2007 at the used car lot for 16,000+ and I got my 2009 for $1000 more a whole lot cheaper than the turbo package plus a new car! Honestly I am very dissapointed from HKS for not delivering more! check it out for yourself here.
