I have owned both NA and TT I have had plenty of fun in both... if you push an NA hard in an autocross or track session it can be real fun.... TT's are more fun for power and straighline purposes obviously... but rather than always saying "sell your NA get a TT" like EVERYONE ALWAYS SAYS be original and say do something else with your NA that doesn't require tons of power.... maybe drive to the supermarket in a drifting fashion I don't know (note I do not condone street craziness) but this is my tangent on why I am tired of hearing the same response to any NAer's questions... NA's are Z's too... there is my speal... but I am still making my car a TT :)
